Non Technical Summary
Demand for minimally processed, clean label food and beverages is on the rise. Food industry attributes this phenomenon to consumers desire for products with health promoting nutrients and bioactive compounds intact with no or minimal use of synthetic ingredients. We propose to investigate the factors influencing microbial safety and quality of food and biological materials treated by isostatic and high pressure based ultra-shear technologies . Efforts includes development of a prototype lab scale UST equipment for investigating microbiological safety of UST processed foods. The influence of various high pressure process parameters including pressures, temperatures, dwell times, and shear intensity on microbiologicalinactivation suspended in low-acid food matrices will be studied. A pilot scale UST equipment will be constructed for the evaluation of food quality, nutritional and sensorial benefits of selected low-acid liquid foods using industrially relevant conditions. Knowledge gained from this project will be disseminated among food industry professionals via webinars, short courses and workshops as well as hands-on boot camps. Educational modules on process engineering, food safety and quality aspects ofhigh pressure based technologieswill be developed. In summary, the underpinning science and prototype equipment developed during this project would help the equipment manufacturers, food processors and regulators to evaluatehigh pressure basedtechnologies for the preservation of various clean label products with extended shelf life.

Goals / Objectives
1. Investigate factors influencing microbiological shelf life of pressure treated low-acidfood matrices (particularly for bacterial spores) during isostatic pressure processing incombination with heat and other lethal agents.2. Investigate the influence of selected ultra-shear technology (UST) process (upstreamand downstream parameters) of pressures, temperatures, and dwell times, shearintensity on bacterial spore inactivation.3. Investigate the influence of selected isostatic as well as UST process on texture andquality attributes of selected low-acid food matrices.
Project Methods
High-pressure experiments will be conducted using batch and pilot scale high-pressure processors available at the advanced food technology pilot plant. Target indicator microorganisms will be processed using a wide range of high-pressure, thermal, and holding time conditions. Microbiological shelf life of selected low-acid food matrices will be experimentally evaluated. Ultra shear technology experimental apparatus will be custom fabricated. We will construct the laboratory equipment with the assumption that UST relies on the combined effects of high pressure exposure, highshear, cavitation and thermal exposure to achieve the desired effects of improved food sensory and nutritional qualities as well as the bacterial spore inactivation. The influence of UST process parameters (pressure differential across UST valve, final process temperature, and shear and cavitation intensities) on temperature and pressure histories of different food matrices will be investigated. Experiments will utilize up to six different low-acid food matrices and corresponding pressure and temperature values at various stages of operation will be documented. Experiments will be performed to identify the significance of shear and cavitation on spore inactivation using representative low-acid food matrix (formulated from dairy or vegetable ingredien - such as carrot puree or whey-protein solution). By suitably varying different shear and cavitation intensities, we can understand relative significance of shear and cavitation on spore inactivation and importance of controlling these parameters along with final process temperature and pressure differential during UST treatment. Upon establishing the relative importance of shear and cavitation intensities on spore inactivation, additional experiment will be conducted to understand the influence of selected UST parameters.The microbiological analysis will be conducted in food microbiological laboratories of the Department of Food Science and Technology. Bacterial cultures will be obtained from the culture collection of The Ohio State University or purchased from the ATCC or National Food Processor Association. The treated microorganisms will be recovered using standard microbiological methods.Kinetic models will be developed based on various approaches (linear, non-linear and mechanistic or thermodynamic based models). The advantages and limitations of models for industrial food processing will be evaluated. Results of this study will benefit the food processors and regulators in the application of high pressure based technologies in the preservation of various food and beverages. Consumer's benefit from the availability of safe extended shelf stable foods with improved product quality, appearance, and nutritive value.

Impacts
What was accomplished under these goals? The effects of pressure, temperature, and shear and their interactions on selected quality attributes and stability of milk during ultra-shear technology (UST) were investigated. Ultra Shear Technology experiments include pressure (400 MPa) treatment of the milk sample preconditioned at two different initial temperatures (25 °C and 15 °C) and subsequently depressurizing it via a shear valve at two flow rates (low - 0.15-0.36 g/s and high - 1.11-1.22 g/s). Raw milk, high-pressure processed (HPP) (400 MPa, ~40 °C for 0 min and 3 min) as well as thermal treated (72 °C for 15 s) milk samples served as the controls. The impact of different process parameters on milk quality attributes were evaluated using particle size, zeta potential, viscosity, pH, creaming, lipase activity, and protein profile. Pressure-only (HPP) treatment did not cause apparent particle size reduction but increased the sample viscosity up to 3.08 mPa.s as compared to 2.68 mPa.s for raw milk. Moreover, it produced varied effects on creaming and lipase activity depending on hold time. Thermal treatment induced slight reduction in particle size and creaming as compared to raw milk. The UST treatment at 35 °C reduced the effective diameter of sample particles from 3511.76 nm (raw milk) to 291.45 nm. This treatment also showed minimum relative lipase activity (29.93%) and kept milk stable by preventing creaming. The differential effects of pressure, shear, temperature, and their interactions were evident, which would be useful information for equipment developers and food processors interested in developing improved food processes for dairy beverages. The combined pressure (0.1 MPa and 600 MPa) and thermal (30, 65, 75, 90 and 105 oC) treatment effects on the binding properties of egg white avidin were investigated using fluorescence spectroscopy titrations with fluorescein-labeled biotin for various holding times (up to 45 min.). Pressure treatment was carried out in a high- pressure kinetic tester whereas heat treatment was conducted using metal tubes in a temperature-controlled oil bath. Avidin binding activity and strength decreased by approximately three orders of magnitude with increases in temperature and holding time, while the binding free energy (-52.3 ± 0.47 kJ/ mol) remained unaffected by high pressure (600 MPa at 30 oC) treatment. The thermal inactivation rate constant ranged from 0.009 to 0.793 min-1 at 65 to 105 oC, 0.1 MPa. Combined pressure (600 MPa)-thermal (65 to 105 oC) treatment reduced the corresponding values by a factor of 2-9, resulting in inactivation rates that ranged from 0.001 to 0.422 min-1. Activation energies for avidin inactivation were 120 ± 10 kJ mol-1 and 149 ± 8 kJ mol-1 for thermal and combined pressure-thermal treatment, respectively. In conclusion, while heat treatment alone destroyed biotin binding strength of avidin, combined pressure and heat exhibit antagonistic effects on avidin-biotin binding energies. A study investigated the inactivation kinetics of Enterococcus faecium in peanut butter under different water activities (aw) and superheated steam temperatures. Peanut butters were prepared at 4 different water activities (0.19, 0.40, 0.60, and 0.80) and E. faecium was inoculated into the peanut butter (7.4-8.7 log CFU/g). The inoculated peanut butter samples were exposure at 4 different superheated steam temperatures (125°C, 175°C, 225°C, and 250°C). Survivor data were modelled using Weibull and log-linear models to describe the inactivation kinetics of E. faecium. The decimal reduction times (D-value), temperature sensitivity (zT) and a­­w sensitivity (zaw) of the D-value were determined from a log-linear model, and inactivation parameters from the Weibull model were also evaluated. An increase in aw and superheated steam temperature decreased the D-value of E. faecium. The zaw-value and zT-value were determined to be 0.60 ± 0.09 and 194.66 ± 40.69°C, respectively (R2 > 0.89). The inactivation kinetics of E. faecium in the peanut butter investigated in this study can provide comprehensive information to superheated steam treatments which may be applied to product and environmental surfaces for effective microbial inactivation without the introduction of water.

Impacts
What was accomplished under these goals? Modern health conscious consumers demand minimally processed additive free "clean-label" foods with health promoting nutrients preserved. To satisfy consumer demand, US food processors began the application of high pressure based technologies for various minimal processing of meat, seafood, juices, salads among others from 1997 onwards. In 2015, the market share of pressure treated foods is estimated at $10 billion dollars. The market share of pressure treated products continue to steadily increase. Many of the high pressure processed foods are introduced by small and medium size entrepreneurs who rely upon university researchers for developing underlying science for their commercilization efforts as well ensure microbiological safety of the processed product. Despite commercial implementation of high pressure-based technologies, very limited public domain literature is available on microbial shelf life of pressure pasteurized orambient temperature stablefoods and factors influence them. Our research contributes to addressing these needs.We investigate the impact of pressure treatment on the inactivation of various pathogenic and spoilage organisms during high pressure processing. Food processors and regulatory agencies utilize such scientific information to identify safe ("safe harbor") processing conditions for introducing pressure treated products desired by the consumers. We investigate quality of pressure treated products and food processors can utilize the information to optimize commercially relevant process conditions for manufaturing food products desired by the consumers. Though many liquid foods (such as juices) have been commercialized using isostatic pressure treatment, batch nature of the high pressure processing restricted widespread industrial adaptation in the liquid beverages such as dairy based beverages, cheese sauces and juices. Thus, beverage manufacturers desire development of high-pressure based continuous flow technological solutions. Our research address such need by developing prototype lab and pilot scale continuous ultra-shear technology equipment in collaboration with industrial partner that enable us to systematically conduct scientific studies on microbial safety and quality of pressure treated beverages. Knowledge gained in the study will also help the industry to scale up and manufacture commercial scale continuous high-pressure equipment. We collaborated with an equipment provided and custom fabricated and installed bench scale ultra-shear technology equipment (Pressure Bioscience) by May 2019. The unit can deliver pressures up to 400 MPa and temperature controlled. Key components include raw liquid food reservoir tank, pressure-generating system, and pressure chamber, shear valve and processed product receiver.The equipment components can be modularly interchanged to create different desired treatment effects by manipulating various combinations of pressure, temperature and shear of the test fluid. Equipment provider trained OSU personnel on basic operation of the equipment. Subsequently OSUeffortsfocused on developing a sanitation protocol for UST equipment to ensure microbial sanitation of treated test samples. We utilized a combination of Tergazyme solution and peracetic acid 5%. Tergazyme solution (pH 9.5) is a mixed of anionic detergent and protease enzyme for presoaking proteinaceous soils and hard-to-remove stains. While, Peracetic Acid 5% (pH 2.5) based cleaning in-place sanitizer is a peroxyacetic acid based liquid disinfectant for food and beverage industry.Results indicated that proposed sanitation procedure appears to be effective. Subsequently experiments were conducted with two high pressure resistant spoilage lactic acid bacteria namely Pediococcus acidilactici PO2 ATC64 and Lactobacillus brevis OSU. Experiments were conducted at 345 MPa, 25oC. During high flow rate at 345 MPa caused significant inactivation of Pediococcus acidilactici with 5 log reduction compared to the same pressure at low flowrate. Low flowrate inactivated P. acidilactici in similar log reduction after processing with batch high pressure at 600 MPa and temperature of 25°C. Currently experiments are under progress with moderately pressure resistance bacterial spores (Bacillus cereus). Experiments carried out to evaluate the effect of shear under pressure (207, 276 and 345 MPa) at two different shear flow rates (slow and fast) on the particle size distribution of raw milk,raw milk. The temperature of the fluid milk after UST valve instantaneously increased as a function of applied pressure, flow rate through shear valve and initial sample temperature. The temperatures at shear valve exit under low and high flowrates were measured as 69.52±1.5°C and 65.48±1.5°C respectively in 70°C experiments and 30.50±5.1°C and 38.24±2.8°C respectively in 40°C experiments. UST treatment shifted entire particle size distribution of processed volume towards lower particle size. Fast and slow flow rate influence on particle size distribution of liquid foods samples seems to be product matrix dependent. The polydispersity of UST treated samples were lower than that of control samples which imply UST treatment enabled uniform particle size distribution after the treatment. Viscosity of 70°C UST treated samples at low and high flowrate were 3.11 and 2.97cP respectively which were higher than untreated milk viscosity (2.68cP). The untreated milk showed creaming rate of 14 ml/100 ml whereas the UST treated samples had no creaming. SDS PAGE revealed retention in native protein fractions and lesser protein denaturation in 40°C UST samples. In another experiment, the pressure-thermal resistance of various spoilage bacteria for batch high pressure processing were evaluated. Tested organisms include Leuconostoc mensentroides, Lactobacillus plantarum, Lactobacillus fermentum, Lactobacillus brevis and Pediococcus acidilactici. These species were suspended (~109 cfu/mL) in 0.05 M HEPES buffer (pH 7.4) and screened at 600 MPa for 5 min pressure holding time at 10?C and 25oC process temperatures using laboratory-scale pressure tester. Two highly pressure resistant species, identified from the preliminary experiments, were subsequently used for developing inactivation kinetic model parameters for LAB bacteria at 600 MPa for various temperatures (10, 25 and 50oC). Thermal inactivation was studied at 50, 60 and 70oC using capillary tube method. Populations of LAB decreased between 0 to 3 logs during pressure come-up time. Among the organisms tested, Pediococcus acidilactici and Lactobacillus brevis, were among the most pressure-resistance organisms. Treatment at 600 MPa pressure and 10oC for 5 mins decreased P. acidilactici and L. brevis populations by 5-log and 1-logs respectively. Pressure-thermal treatment accelerated the inactivation of the bacteria compared to thermal processing alone. Inactivation also increased with increase in pressure holding time (5 to 20 min) regardless of processing temperature. First order kinetic model described adequately the inactivation of P. acidilactici and L. brevis by heat and the inactivation of P. acidilactici by high pressure. On the other hand, inactivation of L. brevis showed a non-linear behavior under elevated pressures and a Weibull model best described the inactivation behavior.
