High Pressure Processing Of Cashew Milk, Rachel Coggins
Department of Food Science and Technology: Dissertations, Theses, and Student Research
Plant-based foods are becoming increasingly popular because of changing consumer preferences. Most plant-based milks are not a direct replacement for cow’s milk because they do not have the same nutritional value and physicochemical properties. However, these properties could be modified and enhanced through processing. For example, high pressure processing (HPP) can affect irreversibly protein structure and functionality and potentially enhance enzymatic hydrolysis. HPP is used widely in the beverage industry for cold pasteurization.

Research conducted in the past couple of decades has showcased the importance of the gut microbiota in human health and well-being. While many studies have reported on the differences in community membership between a disease state and a healthy state, few have investigated the mechanisms through which an aberrant microbiota contributes to a disease phenotype. One of the primary reasons for this are the many technical and ethical barriers to conducting the necessary studies directly in human individuals. Human microbiota-associated (HMA) porcine models have the potential to become important research tools which can enable the testing of hypotheses regarding host-microbiota …

Knowledge-Informed Data-Driven Modeling Of Microbial Inactivation In Food, Steve Zhang, Firnaaz Ahamed, Hyun-Seob Song
UNL Student Research Days Posters, Graduate
Prevention of the growth of harmful microorganisms in food products is an important requirement for ensuring food safety and quality. Mathematical models to predict the quantitative changes in microbial populations in food to the variations of environmental conditions are useful tools in this regard. Current approaches that use empirical formulation generate arbitrary forms of model equations, impeding systematic analysis towards identifying key factors governing microbial growth and inactivation in food. To address this challenge, we present a data-driven modeling pipeline that enables automatic discovery of model equations (through parsimonious selection of relevant terms in a pre-built library) without having to …
