Non Technical Summary
Modeling becomes an important approach to a diversity of problems encountered in the food industry. Models will allow foroptimization of food processes, resulting in better process control. Thus, product development and processing may beimproved, with increased process efficiency. As a result, food quality will be improved, with decreased health risks andincreased consumer satisfaction. Escherichia coli O157:H7 is clearly a public health concern, since this microorganism hasbeen associated with foodborne outbreaks from consumption of spinach, lettuce, and other leafy vegetables. Since currentproduction and processing practices cannot ensure pathogen-free fresh and fresh-cut produce, effective food safetyinterventions are needed for implementation throughout the production, processing, and distribution of these foods. On August22, 2008, the Food and Drug Administration (FDA) published a final rule that allows the use of ionizing radiation to make freshiceberg lettuce and fresh spinach safer and last longer without spoiling. Many researchers have shown that irradiation killspathogens or markedly reduces pathogen counts. We at Texas A&M University have established a sound research program infood safety engineering with emphasis on the application of electron beam irradiation. However, there is still work to do, since abag of baby spinach leaves may not receive the dose in a uniform manner, leaving some parts of the food untreated. We areconfident our intervention strategy will provide successful treatment of fresh and fresh-cut produce. The overall objective of thisproposal is to develop an integrated protocol for improved pathogen inactivation at maximum retention of fresh and fresh-cutproduce quality attributes. The central hypothesis for the proposed research is that ionizing radiation, if it is applied correctly andin combination with dose-reduction strategies, such as anti-microbial agents (cinnamaldehyde, eugenol, etc.) and/or modifiedatmospheric packages, is the best option. Additionally, a quantitative assessment of both the expected benefits and expectedcosts of the various irradiation technologies in a risk-analytic framework can provide support investments in these technologies.We plan to test the central hypothesis and accomplish the overall objective of this proposal by pursuing the following twospecific objectives: (1) Determine the best dose-reduction strategies to combine with irradiation to treat fresh and fresh-cut fruitsand vegetables (2) Establish the most cost effective technology evaluated in (1), using quantitative risk analysis approach

Goals / Objectives
Material characterization: (1) identifying the influence of the matrix (e.g., protein) intrinsic characteristic and the conditions of the surrounding media (e.g. temperature, pH, ionic strength, shear rate) during their encapsulation and isolation, to enhance entrapment efficiency and stability; and (2) characterizing their stability and bioavailability at different gastro-duodenal conditions.Vacuum frying: (1) vacuum impregnate potato slices with high phenolic component to enrich the nutritious value of potato chips; (2) vacuum frying impregnated potato slices at different temperatures; (3) determine the kinetics of product degradation (phenolic) during frying.Safety of minimally processed leafy vegetables: determine the growth rate of listeria in spinach leaves under lower temperature
Project Methods
- Different materials (natural food polymers) will be evaluated to determine the most cost effective one for encapsulation- Fresh leafy vegetables will be contaminated with different pathogens and the growth rate will be evaluated at different temperatures. Prediction models will be used to fit the experiment data in function of time and temperature- phenolic compounds from red beets and green tea extract will be used to vacuum impregnate potato slices, then these slices will be fried at different frying systems (vacuum and atmosphere pressure); the effect of pressure and time on impregnation will be evaluated; the effect of temperature on the phenolic retention will be studied

Impacts
What was accomplished under these goals? Vacuum frying: Evaluated the effect of structural alteration of potato tissues by using divalent ions on oil uptake, texture, and color of deep-fat fried potato chips. The structure modification was achieved by sonication-assisted vacuum impregnation (SVI), with varying sonication times and soaking concentrations of MgCl2. The combination of sonication and vacuum impregnation showed a synergistic effect on reducing oil uptake, with the highest oil reduction values of 20% at 50 min treatment time (15000 ppm) and 17% at 30 min sonication time, in comparison to samples pretreated with no sonication vacuum impregnation (NSVI) and sonication only (S), respectively. Compared to the control, SVI treated samples, treated with 15000 ppm for 50 min, had 41% less oil content. The SVI pretreatment significantly (p < 0.05) affected product texture, color, shrinkage, and porosity. The concentration of MgCl2 affected significantly (p < 0.05) the water loss and magnesium uptake. SVI treated samples absorbed 29% more magnesium than the NSVI samples for the 15000-ppm solution concentration. For the 50000-ppm solution, the SVI samples absorbed 15% more than the NSVI ones. Sensory evaluation results indicated that pretreated potato chips (SVI - with 15000 ppm MgCl2) are acceptable to consumers. Significant difference (p < 0.05) was only observed in the sensory attribute "texture". Potato chips treated with combined MgCl2 and CaCl2 received a significant (p<0.05) higher score than the other two treatments. Microscopic analysis of SEM images showed a well-intact cellular structure and thicker middle lamelae after SVI treatment compared to the control samples. The application of sonication-assisted vacuum impregnation is effective for reducing oil uptake and improving overall quality of deep-fat fried potato chips, by means of delivering divalent ions into raw potato tissues, stabilizing the cellular structure. Nanotechnology The functional characteristics of protein-based complexes for use as carrier systems of Purple Sweet Potato (PSP) Anthocyanins (ACN) were evaluated using rheological, physical and microscopy principles. Four different concentrations of PSP-ACN stock solution (2, 5, 15, and 25 mg) were mixed with 20 μM of protein in NaCl solution (final mix concentration) from three different types of protein: soy protein isolate (SPI, 90% protein), whey protein isolate (WPI, 90-92% protein), and alpha-Lactalbumin (alpha-L, 90%). Stability at two pH 1.35 and 7.45 was also evaluated. Dynamic oscillatory tests on dilute biopolymer solutions were performed at 23°C to determine the relaxation time and a critical frequency value (CFV) to characterize the structure of the protein-based complexes and explain why some proteins yield more stable and efficient matrices. Higher concentrations of PSP-ACN yielded lower CFVs and this trend was more significant (P < 0.05) for the WPI samples. The SPI complexes produced smaller structures at the 5-25 mg/L concentration levels (lower CFV values) which were also more sensitive to shear -i.e., frequency. Transmission Electron Microscopy (TEM) was carried out to observe distribution and size of the particles within the protein matrix. These observations correlated well with the entrapment efficiency (EE %) and loading capacity (%LC) of the complexes. The alpha-Lactalbumin samples had higher entrapment efficiency, loading capacity, and PSP-ACN to protein ratios while the soy protein isolate (SPI) complexes yielded the lowest ratios at all concentrations, mainly due to the amount of electrostatically precipitated protein remaining constant and unaffected by changes in the PSP-CAN concentration. The increase in EE% with increasing PSP-ACN concentration resulted in better entrapment ratios for WPI and alpha-L but not for SPI. Results provide new knowledge on the functional and rheological properties of selected protein-based complexes for use as effective purple sweet potato anthocyaninscarriers.
