Non Technical Summary
The project described here, "Sustainable Processes and Practices for Food, Fuel and Human Health", will provide the means to address emerging challenges to Iowa's agricultural productivity from economically, environmentally and socially sustainable perspectives. The project is aligned with the Department of Food Science and Human Nutrition's Strategic Plan and involves work across three of our five Departmental Signature Areas: 1) Green Technologies for Food and Fuel, 2) Bioactive Compounds for Health and Wellness and 3) Safety and Quality of Foods. Impacts of this project will include new means for ensuring economic, environmental and social sustainability through: diversion of low-value or waste products from agricultural production streams toward valuable end uses; exploration of new crops and modification of organisms or materials derived from them for enhanced yield, recovery or functionality; and development of new technologies or processes for improving the safety, functionality, consumer acceptance or nutritional quality of foods, fuels, and/or biomaterials. Common to these diverse goals will be a focus on dissemination of results, processes and capabilities to end users in Iowa and beyond. These technology transfer, extension and outreach activities will maximize the value of our research activities to project stakeholders.The multidisciplinary project described here will impact various facets of Iowa and national agriculture including, supply, farming practices, industry need for alternative ingredients and chemicals, nutrition and health, food quality and safety, energy production and economic feasibility. The expected outcomes, and those which will provide direct indications of the success of this project include: increased value and utilization of agricultural commodities and under-valued by-products, improved land management, a reduction in waste streams and enhanced energy independence. Other indicators will include wider availability of healthful food ingredients and food products, improved cooperation with other universities, state and federal agencies, commodity boards, industries and communities. As an academic institution, a fundamental outcome of this project will be training of our graduate students for their future leadership roles in the state, regional, national and global agricultural economies. Transferring the technology, processes and knowledge resulting from these efforts will greatly aid economic development, industrial growth, rural development and promote agricultural excellence in the state.

Goals / Objectives
The ultimate goal of this work is to maintain and improve the quality of human life through advancements in agriculture. Major obstacles to achieving this goal include scarcity or limitation of natural resources, impact of climate change on established agricultural practices and negative influences on human health mediated by environmental, behavioral or microbiological factors. In this project, we will address these challenges through development and dissemination of sustainable processes and practices for food, fuel and human health. These proactive processes and practices will 1) add value to or capitalize on otherwise underutilized agricultural waste streams, 2) explore use of new crops and improve crops, animals, microorganisms or their products in order to enhance their yield, recovery, functionality and/or human health benefits and 3) result in new technologies and processes designed to improve the safety, behavior, functionality and/or nutritional quality of foods, fuels and/or biomaterials and to ensure consumer acceptance.Objective 1: To leverage agricultural commodities, low-value co-products or wastes from food processing and bioprocessing operations or fermentations as sources of compounds, materials and/or end products of value to industry and consumers. Divert agricultural wastes toward valuable end uses while simultaneously reducing the need for landfilling, incineration and other inefficient, costly and environmental burdensome methods of disposal (economic and environmental sustainability).Objective 2: To improve or modify crops, animals, microorganisms or materials derived from these sources (starches, lipids, enzymes, other proteins, peptides, etc.) and enhance their yield, recovery, functionality and/or human health and safety benefits. These improvements may be realized through breeding, selection, genetic and metabolic engineering of organisms or through chemical, enzymatic and physical processing of materials derived from these organisms. Use of new crops with novel functional, health or safety benefits may also be explored (economic and environmental sustainability).Objective 3: To develop new technologies and processes aimed at improving the safety, behavior, functionality and/or nutritional quality of foods, fuels and/or biomaterials. These will include physical and chemical processing approaches intended to reduce or eliminate pathogens and spoilage organisms or to preserve the structure, function and nutritional availability of important food biomolecules. In parallel with these improvements, high standards for food quality and consumer acceptance will be maintained. Methods for the separation, concentration and rapid detection or quantification of microbial pathogens and spoilage organisms will also be developed. These technologies and processes will promote energy independence, increase the health benefits of foods and reduce negative economic and health impacts of food spoilage or microbial contamination (economic and social sustainability).Objective 4: Technology transfer: identify, develop, implement and disseminate technology related to the processes and practices described above. Adoption of the processes and practices developed within this project will benefit the food, bioeconomy, bioproducts, diagnostics, health and medical sectors of industry as well as consumers. Benefits to industry and consumers will extend locally, nationally and globally (economic, environmental and social sustainability).
Project Methods
Due to the limitation of the system we were unable to list on the participants page the following additional co-PDs: Clark Ford, 8725: Food Science & Human Nutrition; Lawrence Johnson 8725: Food Science & Human Nutrition.The general methods to be used to conduct this work are described below, separated according to objective.Objective 1: To leverage agricultural commodities, low-value co-products or wastes from food processing and bioprocessing operations or fermentations as sources of compounds, materials and/or end products of value to industry and consumers. Low-value agricultural materials, including food wastes, lignocellulosic wastes (corn stover), soy whey or soy cotyledon fiber, grape seeds, etc. will be sourced from institutional, industry or academic partners so that they may be further processed for removal and concentration of bioactive compounds, or transformed via fermentation for generation of desirable materials or end products. Traditional and newly developed methods for fractionation, purification and biological, chemical or physical assay will be used to isolate, characterize and test active, high-value components from agricultural waste streams. New or improved processes for energy or biogas production from these waste streams will be developed. Principles of Agricultural Economics and Life Cycle Analysis will be applied to optimize processes and promote economic and environmental sustainability.Objective 2: To improve or modify crops, animals, microorganisms or materials derived from these sources (starches, lipids, enzymes, other proteins, peptides, etc.) and enhance their yield, recovery, functionality and/or human health and safety benefits. Traditional breeding, genetic engineering and other methods for creation and/or selection of cultivars, individuals or isolates having desirable genetic, physiological or genetic characteristics will be applied. Microbial, physical, chemical or enzymatic transformations of starting materials will be used to promote desirable processes resulting in enhanced product yield, recovery or health and nutritional impact or to generate modified molecules or materials having unique and advantageous properties.Objective 3: To develop new technologies and processes aimed at improving the safety, behavior, functionality and/or nutritional quality of foods, fuels and/or biomaterials. "Greener" methods for food processing or materials extraction will be developed as alternatives to economically or environmentally unsustainable practices, these will include aqueous processes for extraction and separation of oils, bioactive compounds and more efficient means for disruption of food matrices and plant, animal or microbial cells for bioproduct recovery. Physical, chemical or enzymatic processes for modification of food ingredients or other inputs such as biofuels or biomaterials will be used to improve the safety, behavior, functionality or nutritional quality of these starting materials. New antimicrobial formulations, including additive or synergistic blends or systems, will be developed, tested and applied to foods. More efficient means for microbial sampling, pre-analytical sample preparation and detection will be developed for more rapid or sensitive detection and characterization of foodborne pathogens and spoilage organisms.Objective 4: Technology transfer: identify, develop, implement and disseminate technology related to the processes and practices described above. Mechanisms for technology transfer will include extension activities (visits to growers, wholesalers or processing plants, workshops, webinars, extension bulletins, CD's, etc.), media coverage provided by the Iowa State News Service, local or national media outlets, reports to funding agencies, presentations at scientific meetings (talks, posters, symposia), deposition of theses and dissertations, publication in peer-reviewed scientific journals and patenting and licensing of inventive aspects of the work.

Impacts
What was accomplished under these goals? The overall goal of this project, "Sustainable Processes and Practices for Food, Fuel and Human Health", was to help promote and ensure Iowa's continued agricultural productivity and sustainability. Approaches and activities through which this has been achieved include diversion of low-value or waste products from agricultural processes towards valuable end uses, enhanced yield, recovery or functionality for agricultural processes through modification of crops, organisms or materials derived from these, and development of new processes or technologies for improving the safety, functionality, consumer acceptance or nutritional quality of foods, fuels or biomaterials. Over the course of the project, project members leveraged low-value agricultural wastes to develop value-added products and processes to produce improved foods and feeds, to create biomaterials having desirable properties, and to establish improved natural alternatives to chemical food preservatives. Microorganisms or their enzymes were modified for enhanced product yield and foods or ingredients having improved characteristics or functionalities were developed. New approaches for environmental remediation or instrumental methods for improved characterization of food quality or nutrition were also described. Novel approaches for the rapid detection and inactivation of foodborne pathogens were developed. Through these activities, project personnel providednew approaches for feeding, powering or maintaining the health of the people of Iowa. Project activities impacted various facets of agriculture, from production to consumption, at both the state and national levels. Benefits include increased value and utilization of agricultural commodities and under-valued by-products, a reduction in material entering agricultural waste streams, availability of more healthful food ingredients and food products, and enhanced energy independence. Project impacts also extended beyond foods, feed and fuel, providing industry with advancements in areas such as materials science and environmental remediation. Technology transfer is vital to the productive and beneficial use of the knowledge, processes or materials generated through this project. Therefore, project outputs have been disseminated through various channels, including extension activities (workshops, webinars, bulletins, etc.), media coverage (University- or College-level news releases, Center or Departmental newsletters, social media channels, etc.), publication in peer-reviewed journals, presentations at scientific meetings, deposition of theses and patenting or licensing of inventive aspects of project activities. Access to the knowledge, processes or materials generated through this project has played a facilitative role in promoting human health, productivity and agricultural sustainability in the state and beyond.

Progress 10/01/16 to 09/30/17

Outputs
Target Audience:Target audiences reached this reporting period were the general public, small, medium and large food processors, growers, wholesalers and distributors, industries, agencies and associations affiliated with the state's bioeconomy efforts, regulatory and academic personnel. At our institution, those reached include administrators, faculty, staff, graduate students, undergraduate students (including USDA-NIFA-funded Cyclone Scholar undergraduate summer research program participants), postdoctoral researchers and visiting scholars. Academics at other institutions were also reached. The general public and other stakeholders were reached through news coverage from College, University, local or national news services, faculty and departmental website content. Efforts to reach small, medium and large food processors and other sectors of industry included extension and outreach activities, including direct communications, website content, presentations in training seminars, workshops or webinars or at scientific/professional meetings. Efforts to reach academic personnel included direct personal interactions, training and development of new research techniques, publication of peer-reviewed research papers, articles in relevant trade publications, oral or poster presentations at scientific meetings and recruitment materials (presentations, flyers, website content, etc.). Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?The project has facilitated training and professional development of undergraduate (including participants in the USDA-NIFA-funded Cyclone Scholar Research program) and graduate (MS, PhD) students and postdoctoral trainees, and results have been incorporated in teaching curricula. The project has facilitated both training (knowledge acquisition) and professional development (skills acquisition) of industry and regulatory stakeholders. How have the results been disseminated to communities of interest?Results from work under this project have been disseminated to stakeholders/communities of interest through publication in peer-reviewed journals and in invited book chapters and patents/patent applications, through oral and poster presentations at national and international meetings, through invited talks to audiences comprised of industry, regulatory and academic stakeholders, through internet publication of policy briefs and through one-on-one outreach and extension efforts via phone, email or in-person contact. What do you plan to do during the next reporting period to accomplish the goals?For the next reporting period, we will continue to use the dissemination channels described above to distribute the appropriate information on results to our stakeholder communities.

Impacts
What was accomplished under these goals? IMPACT: Increased knowledge and new processes which improve the safety, behavior, functionality and/or nutritional quality of foods, fuels and/or biomaterials. Obj 1:Leverage agricultural commodities, low-value co-products or wastes from food processing and bioprocessing operations or fermentations as sources of compounds, materials and/or end products of value to industry and consumers. Soy phospholipids ("gum", "lecithin") are by-products of edible soy oil production with value-added applications in the food industry as an emulsifier or anti-sticking agent. Project personnel investigated the impact of phytosterol content on liposomal particle size and encapsulation efficiency. Data obtained will provide the food, pharmaceutical and nutraceutical industries with changes in knowledge, enabling their use of inexpensive phospholipid mixtures for delivery of bioactive agents. Shipping of Distillers dried grains with solubles (DDGS), a by-product of the expanding bioethanol industry, often results in undesirable defects (caking, clumping) that impair product flow. To better understand this issue, DDGS were combined with distillers wet grains and dried under varying conditions of temperature, pressure and time. Results yielded a better understanding of factors affecting mass flow rate (a change in knowledge), which will extend the range from the production site over which DDGS may be marketed (changes in action and condition). In efforts to better serve animal feed markets, methods for increasing the nutritional value of DDGS through physical processes such as sieving and aspiration were also investigated. Smaller oil- and protein-rich particles were separated from larger, fiber-rich particles through particle sieving, followed by aspiration-based condensation of DDGS oils and proteins. Modification of physical and nutritional properties intrinsic to raw DDGS will provide industry with methods to obtain animal feed ingredients having improved properties and the ability to command a higher price in the value-added products market (changes in knowledge, behavior and condition). Additionally, conditions for low-moisture anhydrous ammonia (LMAA) pretreatment of corn stover were optimized in order to provide an efficient means for delignification, swelling and preservation of polysaccharide content prior to cellulosic ethanol fermentation. Dissemination of this knowhow to industry will effect changes in knowledge and condition for stakeholders in the biofuels industry. Obj2: Improve or modify crops, animals, microorganisms or materials derived from these sources (starches, lipids, enzymes, other proteins, peptides, etc.) and enhance their yield, recovery, functionality and/or human health and safety benefits. The bacterium Bacillus licheniformis was metabolically manipulated to improve its ability to produce industrially-valuable poly-γ-glutamate (γ-PGA) from the biofuel by-product glycerol. The modified strain produced 16.63gof γ-PGA per liter of biodiesel-derived crude glycerol. Lipase from the yeast Candida antarctica was used to synthesize glucose-fatty acid esters containing palmitic, lauric and hexanoic acid moieties. Resulting products were compared with commercially available sucrose esters for their abilities to stabilize oil-in-water emulsions. This work may provide the food industry with new tools for creating or maintaining emulsions of value to food formulators. Corn protein (zein) is used in environmentally-friendly coatings applied to foods for retaining moisture and preventing contamination. In efforts to develop novel antimicrobial coatings, the impact of antimicrobial titanium dioxide nanoparticles (TiO2 NP) on the thermo-mechanical properties of cast zein films was investigated.TiO2 NP incorporation improved mechanical properties of zein films without affecting water vapor permeability, but did reducefilm elongation-to-break properties. The natural flavorant cinnamaldehyde was investigated for its efficacy as an antimicrobial against E. coli O157:H7 and Salmonella enterica in carrot and mixed berry juices held at refrigeration and mild abuse temperatures. Results indicate that cinnamaldehyde is an effective, naturally-sourced means forenhancing the microbial safety of juice products.The polyionic compounds sodium polyphosphate and polyethylenimine were also shown to enhance the uptake and activities of various plant essential oils against a variety of human pathogens. Amaranth and quinoa were used to formulate gluten-free snack foods and gluten-free pasta based on rice, quinoa and amaranth flours were developed and tested. The availability of palatable and nutritious non-wheat-based foods will provide consumers with practical means for limiting or excluding gluten-containing foods from their diets. Immunization against gonadotropin-releasing hormone enabled reversible,more humane "immuno-castration" of boars and resultedin no long-term effects on the animals' reproductive characteristics. Collectively, these efforts to improve or modify crops, animals, microorganisms or materials derived therefrom will provide beneficial changes in knowledge, behavior and action in stakeholder industries. Obj 3:Develop new technologies and processes aimed at improving the safety, behavior, functionality and/or nutritional quality of foods, fuels and/or biomaterials. Technologies aimed at improving the safety of foods, fuels and/or biomaterials that were worked on during the reporting period include the development of a recombinant multi-antigen vaccine with broad protection potential against avian pathogenic Escherichia coli, development of a sensor array for detection of organic and inorganic contaminants in post-consumer recycled plastics intended for food contact use, use of ultraviolet irradiation as a food safety intervention in a model aquaponics system and physiological investigation of stress-filamented Salmonella cells using flow-through resonant mass measurement. Approaches for improving the behavior of foods and other materials include use of pre-heating, sonication and chemical modification of egg albumen to increase its thermal stability, application of high-voltage atmospheric cold plasma for hydrogenation of soybean oil without generation of trans-fatty acids and hydroxypropylation of high-amylose corn starch for producing edible films with improved properties. Work towards improving the functionality and nutritional quality of foods included the use of rice bran wax and soybean oil oleogels as pork fat replacements to create healthier frankfurter-type sausages and optimization of oleogel structure to ensure protection of retinol palmitate (vitamin A palmitate) activity. Addressing improvements in the behavior and functionality of materials, a new process for value-added, environmentally-friendly manufacture of biocement was developed in which costly reagent-grade CaCl2 was replaced with limestone powder derived from aggregate quarries and acetic acid derived from fast pyrolysis of lignocellulosic biomass. Results indicate that this new process is effective, more sustainable, and cheaper compared with the conventional method. Together, development of the new technologies and processes described under this objective will provide positive changes in knowledge, behavior and action among stakeholder industries. Obj 4:Technology transfer. Project outputs were disseminated through various channels, including extension activities (workshops, webinars, bulletins, person-to-person communications, etc.), media coverage (University- or College-level news releases disseminated locally, statewide or nationally, Center or Departmental newsletters, social media channels, etc.), publication in peer-reviewed journals and professional trade magazines, presentations at scientific meetings, deposition of MS and PhD theses and patenting and licensing of inventive aspects of project activities.

Outputs
Target Audience:Target audiences reached this reporting period were the general public, small, medium and large food processors, growers, wholesalers and distributors, industries, agencies and associations affiliated with the state's bioeconomy efforts, regulatory and academic personnel. At our institution, those reached include administrators, faculty, staff, graduate students, undergraduate students, postdoctoral researchers and visiting scholars. Academics at other institutions were also reached. The general public and other stakeholders were reached through news coverage from College, University, local or national news services, faculty and departmental website content. Efforts to reach small, medium and large food processors and other sectors of industry included extension and outreach activities, including direct communications, website content, presentations in training seminars, workshops or webinars or at scientific/professional meetings. Efforts to reach academic personnel included direct personal interactions, training and development of new research techniques, publication of peer-reviewed research papers, oral or poster presentations at scientific meetings and recruitment materials (presentations, flyers, website content, etc.). Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?Training opportunities made possible through project activities include one-on-one mentoring of undergraduate and graduate (MS, PhD) students and postdoctoral fellows and exchange students and scholars.Project data have also been incorporated into teaching curricula, offering training opportunities through coursework. During the reporting period, professional development activities stemming from the project led to increases in new knowledge or updated skills and included attendance and presentation at national and international conferences and symposia, participation in workshops or seminars and professional development made possible through individual study. Examples of individual study included review of scientific literature during preparation of publications or grants and post-conference follow-up on new topics of interest (literature search and reading, web searching, personal communications via phone or email, etc.). Key conferences, workshops, etc. are listed in the "Conference Papers and Presentations" section of this report. How have the results been disseminated to communities of interest?Results from work under this project have been disseminated to stakeholders/communities of interest through publication in peer-reviewed journals and in invited book chapters and patents/patent applications, through oral and poster presentations at national and international meetings, through invited talks to audiences comprised of industry, regulatory and academic stakeholders, through internet publication of policy briefs and through one-on-one outreach and extension efforts via phone, email or in-person contact. Additional dissemination routes included media channels such as university- or college-level news releases, center or departmental newsletters and social media. What do you plan to do during the next reporting period to accomplish the goals?We will continue our research on the key facets of our work on sustainable processes and practices for food, fuel and human health. New knowledge, impacts, outcomes and advances will be reported.

Impacts
What was accomplished under these goals? The overall goal of this project is to help ensure Iowa's continued agricultural productivity and sustainability. Activities through which this will be achieved include diversion of low-value or waste products from agricultural processes towards valuable end uses, enhanced yield, recovery or functionality for agricultural processes through modification of crops, organisms or materials derived from these, and development of new processes or technologies for improving the safety, functionality, consumer acceptance or nutritional quality of foods, fuels or biomaterials. During this reporting period, project members leveraged low-value agricultural wastes to develop value-added products and processes to produce improved foods and feeds, to create biomaterials and biochemicalshaving desirable properties, and to establish improved natural alternatives to chemical food preservatives. Microorganisms or their enzymes were modified for enhanced product yield, and foods or ingredients having improved characteristics or functionalities were developed. New approaches for immunity-based mitigation of zoonotic diseases were explored. Project activities impacted various facets of agriculture, from production to consumption, at both the state and national levels. Benefits included increased value and utilization of agricultural commodities and under-valued co-products, a reduction in material entering agricultural waste streams, availability of more healthful food ingredients and food products, and enhanced energy independence. Technology transfer is vital to the productive and beneficial use of the knowledge, processes or materials generated through this project. Project outputs were disseminated through various channels, including extension activities, media coverage, publication in peer-reviewed journals, presentations at scientific meetings, deposition of theses and dissertations,and patenting or licensing of new technologies. Ultimately, access to the knowledge, processes or materials generated through this project will promote human health, productivity and agricultural sustainability. Objective 1:To leverage agricultural commodities, low-value co-products or wastes from food processing and bioprocessing operations or fermentations as sources of compounds, materials and/or end products of value to industry and consumers. Methods for leveraging low-value co-products or wastes from food and/or bioprocessing operations were developed and applied toward process or product improvements. Various approaches for improving or optimizing the growth of microalgae were explored, including the use of bio-renewable materials as attachment substrates for algal growth and the use of light filters to select optimalwavelengths for microalgal growth. Project personnel also studied extrusion processing as a method for converting byproduct corn protein meals into other value-added materials such as bioplastics, or other industrial precursors. A significant effort was made toward increasing oil recovery from condensed corn distillers solubles, where synergistic interactions between non-ionic surfactants and silica nanoparticles were found to increase the efficiency of oil extraction by destabilizing the oil-in-water emulsion and washing out free oil droplets. Objective2: To improve or modify crops, animals, microorganisms or materials derived from these sources (starches, lipids, enzymes, other proteins, peptides, etc.) and enhance their yield, recovery, functionality and/or human health and safety benefits. During the reporting period crops, animals, microorganisms or materials derived from these sources were improved in order to enhance yield and functionality. The impact of genetics (waxy gene dosage) and growing conditionson starch structures and properties wasexamined. The impact of genetic modification on maize plant residue, grain yield, grain nutrient composition and stalk nutrient composition, with or withoutuse of glyphosatewas explored. The results showed that insect resistance resulting from genetic modification, in the absence of significant insect pest or weed pressure and glyphosate application, were not likely to significantly alter productivity or nutrient composition of corn residue or grain. The thermal stability and functionality of egg proteins modified using chemical or physical treatments or their combinations were investigated. Novel techniques to elucidate and prevent the mechanism of freeze-thaw-induced egg yolk gelation were developed to improve and extend egg yolk functionality. Objective 3:To develop new technologies and processes aimed at improving the safety, behavior, functionality and/or nutritional quality of foods, fuels and/or biomaterials. Technologies and processes were developed that will improve the safety, behavior, functionality or nutritional quality of foods, fuels or biomaterials. For example, the essential oil component geraniol was used to inactivateEscherichia coliO157:H7 andSalmonellaenterica in fruit and vegetable juices. The effectiveness of broad spectrum produce sanitizers against foodborne pathogens on fruit surfaces was also evaluated. Cold plasma technology was investigated the pasteurization of shell eggs andfor in-package decontamination of cherry tomatoes. Ongoing efforts toward development and evaluation of a poultry vaccine to both improve animal health and mitigate food safety hazards were also carried out. A recombinant antigenwas found to elicit aprotective immune responseagainstEscherichia colisepsis and also ledto significant reductions of the pathogen in both the organs and blood of mice. In food quality and nutrition-related work,extrusion processing of milk protein-rich ingredients was found to produce texturally preferable bars for potential commercial applications and shelf life studies were completed for tofu made by an Iowa Company, measuring both microbial and quality factors. Other projects focused on the thermal stability of egg albumen, effects of interesterification-based changes in lipid structure on fatmelting properties and lipemia, surfactant-based destabilization of peanut oil-based emulsions, structure-function characterization of starch from various sources and theeffects of amylose-to-amylopectin ratios on binding capacity of DDGS and soy-based aquafeeds. The outcomes of this work are expected to have substantial impacts onimproving the behavior and nutritional quality of food and feeds. Progress was also made in biofuels-related work during this period. Specifically, researchers used nanoparticles and processing aids to enhance corn oil partitioning during ethanol fermentation of distillers condensed solubles. The impact of a revolving algal biofilm cultivation system on recovery of nitrogen and phosphorous from municipal wastewater was also investigated. The revolving system is an improvement over traditional raceway systems, recovering nutrients effectively while maintaining a smaller environmental footprint. Algae grown using this system is easily harvested for use in bioplastics, fertilizers, biofuels, aquaculture feed, and other sustainable products. Objective 4:Technology transfer: identify, develop, implement and disseminate technology related to the processes and practices described above. Project outputs have been disseminated through various channels, including extension activities (workshops, webinars, bulletins, etc.), media coverage (University- or College-level news releases, Center or Departmental newsletters, social media channels, etc.), publication in peer-reviewed journals, presentations at scientific meetings, deposition of theses and patenting or licensing of inventive aspects of project activities.

Impacts
What was accomplished under these goals? The overall goal of this project is to help ensure Iowa's continued agricultural productivity and sustainability. Activities through which this will be achieved include diversion of low-value or waste products from agricultural processes towards valuable end uses, enhanced yield, recovery or functionality for agricultural processes through modification of crops, organisms or materials derived from these, and development of new processes or technologies for improving the safety, functionality, consumer acceptance or nutritional quality of foods, fuels or biomaterials. During this reporting period, project members leveraged low-value agricultural wastes to develop value-added products and processes to produce improved foods and feeds, to create biomaterials having desirable properties, and to establish improved natural alternatives to chemical food preservatives. Microorganisms or their enzymes were modified for enhanced product yield, and foods or ingredients having improved characteristics or functionalities were developed. New approaches for environmental remediation or instrumental methods for improved characterization of food quality or nutrition were also described. Project activities impacted various facets of agriculture, from production to consumption, at both the state and national levels. Benefits include increased value and utilization of agricultural commodities and under-valued by-products, a reduction in material entering agricultural waste streams, availability of more healthful food ingredients and food products, and enhanced energy independence. Project impacts also extended beyond foods, feed and fuel, providing industry with advancements in areas such as materials science and environmental remediation. Technology transfer is vital to the productive and beneficial use of the knowledge, processes or materials generated through this project. Project outputs have been disseminated through various channels, including extension activities (workshops, webinars, bulletins, etc.), media coverage (University- or College-level news releases, Center or Departmental newsletters, social media channels, etc.), publication in peer-reviewed journals, presentations at scientific meetings, deposition of theses and patenting or licensing of inventive aspects of project activities. Ultimately, access to the knowledge, processes or materials generated through this project will promote human health, productivity and agricultural sustainability. Objective 1: To leverage agricultural commodities, low-value co-products or wastes from food processing and bioprocessing operations or fermentations as sources of compounds, materials and/or end products of value to industry and consumers. Methods for leveraging low-value co-products or wastes from food processing and bioprocessing operations were developed and applied toward process or product improvements. Examples, include growth of the cold-tolerant microalga Monoraphidium sp. for simultaneous bioremediation of wastewater and production of lipids having a similar fatty acid profile as soybean oil and suitable for use as feedstock for production of biodiesel, and ozonation of uncooked corn mash for reduction of bacterial contamination in fuel ethanol fermentations. An enzymatic method for conversion of soybean hull solids into soluble sugars suitable for fermentative production of biosurfactants was also developed. A mixture of polysaccharide-degrading enzymes was used to convert up to to 65% of soybean hull solids to soluble carbohydrates. Removal of the remaining unconverted hull solids resulted in a biosurfactant yield that was 60% higher than was obtained with glucose-fed cultures. Objective 2: To improve or modify crops, animals, microorganisms or materials derived from these sources (starches, lipids, enzymes, other proteins, peptides, etc.) and enhance their yield, recovery, functionality and/or human health and safety benefits. Crops, animals, microorganisms or materials derived from these sources were improved in order to enhance yield and functionality. At the genetic level, project personnel characterized the dosage effect of high-amylose modifier genes on starch structure, explored the biotechnological potential of a unique carbohydrate binding element from a hyperthermophilic bacterium and enhanced biosurfactant production by replacement of the native lichenysin promoter. An improved ethanolysis-based method for synthesis of the pharmacologically important biochemical 2-arachidonoylglycerol from arachidonic acid-rich oils was developed. Compared to existing synthesis methods, the new approach is simpler, easier to scale, more eco-friendly and more cost-effective. Objective 3: To develop new technologies and processes aimed at improving the safety, behavior, functionality and/or nutritional quality of foods, fuels and/or biomaterials. Technologies and processes were developed that will improve the safety, behavior, functionality or nutritional quality of foods, fuels or biomaterials. In food safety-related work, a flow cytometry-based method for rapid detection of Salmonella contamination in seed sprouts was developed, peptide nucleic acid probes for identification of the pathogenic yeast Candida albicans were designed and evaluated, and the impact of starvation on radiation resistance and injury in Escherichia coli O157:H7 was characterized in both saline solution and in apple juice. The nutritional and sensory characteristics of pork loins and bacon from chemically castrated barrows were examined, the impacts of different postmortem chilling regimens on sarcoplasmic protein profile and sensory attributes of pork meat were determined and the effects of dietary fat source and concentration on carcass fat distribution and iodine values were identified. Biofuels-related work during this period included improvements in ethanol fermentation using polysaccharide-hydrolyzing enzymes and enhanced mass transfer during syngas fermentation through implementation of a monolithic reactor design. The new reactor design increased ethanol productivity by 53% compared to that obtained using a traditional bubble column reactor. Advancements in biofuel-related algal cultivation were also made during this period. Specifically, the performance and durability of a novel revolving algal biofilm cultivation system were evaluated at the pilot scale over a 1-year period, and the impact of parameters including fluid flow, turbulent mixing and wavelength-selective optical light filter on algal cultivation were examined. Objective 4: Technology transfer: identify, develop, implement and disseminate technology related to the processes and practices described above. Project outputs have been disseminated through various channels, including extension activities (workshops, webinars, bulletins, etc.), media coverage (University- or College-level news releases, Center or Departmental newsletters, social media channels, etc.), publication in peer-reviewed journals, presentations at scientific meetings, deposition of theses and patenting or licensing of inventive aspects of project activities.

Impacts
What was accomplished under these goals? The overall goal of this project is to help ensure Iowa's continued agricultural productivity and sustainability. Activities through which this is being achieved include diversion of low-value or waste products from agricultural processes towards valuable end uses, enhanced yield, recovery or functionality for agricultural processes through modification of crops, organisms or materials derived from these, and development of new processes or technologies for improving the safety, functionality, consumer acceptance or nutritional quality of foods, fuels or biomaterials. During this reporting period, project members leveraged low-value agricultural wastes to develop value-added products and processes to produce improved foods and feeds, to create biomaterials having desirable properties, and to establish improved natural alternatives to chemical food preservatives. Microorganisms or their enzymes were modified for enhanced product yield and foods or ingredients having improved characteristics or functionalities were developed. New approaches for environmental remediation or instrumental methods for improved characterization of food quality or nutrition were also described. Project activities impacted various facets of agriculture, from production to consumption, at both the state and national levels. Benefits include increased value and utilization of agricultural commodities and under-valued by-products, a reduction in material entering agricultural waste streams, availability of more healthful food ingredients and food products, and enhanced energy independence. Project impacts also extended beyond foods, feed and fuel, providing industry with advancements in areas such as materials science and environmental remediation. Technology transfer is vital to the productive and beneficial use of the knowledge, processes or materials generated through this project. Project outputs have been disseminated through various channels, including extension activities (workshops, webinars, bulletins, etc.), media coverage (University- or College-level news releases, Center or Departmental newsletters, social media channels, etc.), publication in peer-reviewed journals, presentations at scientific meetings, deposition of theses and patenting or licensing of inventive aspects of project activities. Ultimately, access to the knowledge, processes or materials generated through this project will promote human health, productivity and agricultural sustainability. Objective 1: Methods for leveraging low-value co-products or wastes from food processing and bioprocessing operations were developed and applied toward process or product improvements. Activities during this period included determining the impacts of processing techniques on the physicochemical properties of distillers dried grains with solubles (DDGS) and condensed distillers solubles (CDS) and effects of DDGS amendment of flours on quality characteristics of bread or extruded fish meal. Value-added cationic polyurethane coatings were developed from soybean oil feedstock and the impact of chemical structure (amine ratio and crosslinking) on thermomechanical and antimicrobial properties of these polymers was determined. The antimicrobial impact of celery juice concentrate, a natural source of nitrate, was examined and compared to conventional nitrate supplementation as a function of both pH and nitrate concentration. The projects addressed in this objective leveraged low-value co-products from processing operations or agricultural waste materials to improve the quality of foods or feed, to develop novel and sustainably-sourced antimicrobial materials and to address consumer and industry demand for natural or "green" alternatives to traditional food preservatives. Objective 2: Crops, animals, microorganisms or materials derived from these sources were improved in order to enhance yield and functionality. Specifically, blends of fully hydrogenated and non-hydrogenated soybean oil were engineered for desired functionalities using emulsifiers and the nano- and mesoscale crystal structures of non-interesterified mixtures of fully hydrogenated fats were functionalized using different shear processing regimens. Various microorganisms or their enzymes were genetically engineered for enhanced properties. For example, the gene for a 2,3-butanediol dehydrogenase of Bacillus licheniformis was deleted, resulting in enhanced production of D-2,3-butanediol in support of biofuel production, a thermostable amylase with unusually high activity was cloned and characterized and isoforms of Synechocystis glycogen synthase were modified using targeted mutagenesis. The work conducted under this objective resulted in improved processes for achieving desired functionalities in food systems or ingredients, enhanced yields of biofuels and greater understanding of metabolic processes fundamental to improved industrial fermentations. Objective 3: Technologies and processes were developed that will improve the safety, behavior, functionality or nutritional quality of foods, fuels or biomaterials. Specifically, the impact of commercial processing techniques and antimicrobial amendments on the safety and consumer acceptance of various meats was explored. Improved understanding of the response of methicillin-resistant Staphylococcus aureus to commonly used thermal treatments was obtained for slab bacon, frankfurters, summer sausage and ham. Greater understanding of the impacts of pH, natural antimicrobials and sodium nitrite was obtained for Listeria monocytogenes on ready-to-eat ham and frankfurters and a thin agar layer method for recovery of pressure- and heat-injured Listeria monocytogenes was developed. Also developed were nano-enhanced protein-based biopolymers, methods for production and quantification of biosurfactants useful in remediation of oil spills, methods for ethanol-ultrasound-assisted fractionation and recovery of products from enzyme-extracted soybean oil, an approach for mitigating ammonia gas emissions from animal housing operations using microalgae, ultrasound-based methods for lysis of cells of the green alga Chlamydomonas reinhardtii and optimized flocculation techniques in support of biofuel production. Means for controlling the properties, behavior, functionality and nutritional content of foods were explored. The effects of heat treatment and moisture content on interactions between lauric acid and starch granules were elucidated, the impacts of modified milk protein concentrates on textural properties of high-protein nutrition bars were studied and the effects of preslaughter feed withdrawal time on carcass, body weight gain and food safety characteristics were determined for pigs reared in a commercial production environment. Instrument-based techniques developed included UV-VIS spectroscopic methods for screening of egg white for yolk contamination, high-resolution time-of-flight mass spectrometry-based metabolic fingerprinting of rat digesta and application of Fourier-transform infrared photoacoustic spectroscopy for measurement of resistant starches in rat cecal contents. Together, the work accomplished under this objective will lead to novel natural antimicrobial interventions for foods, improved processes for ensuring food component fractionation, functionality, quality or performance and superior methods for measuring food quality and nutritional content. Objective 4: Project outputs have been disseminated through various channels, including extension activities (workshops, webinars, bulletins, etc.), media coverage (University- or College-level news releases, Center or Departmental newsletters, social media channels, etc.), publication in peer-reviewed journals, presentations at scientific meetings, deposition of theses and patenting or licensing of inventive aspects of project activities.
