Development Of An Intact Mass Spectrometry Method For The Detection And Differentiation Of Major Bovine Milk Proteins, Emily F. Harley-Dowell
Department of Food Science and Technology: Dissertations, Theses, and Student Research
The authentication of products with claims regarding protein sources or compositions is a challenge for traditional analytical methods, which generally lack the required specificity whole protein analysis can provide. For example, the establishment of milk as “A2” is achieved through genetic testing of cows before milk production, with no methods to authenticate milk products themselves. Establishment of A2 milk is completed through genetic testing of the cows before milk production, but with no methods to authenticate the milk products themselves. Intact protein mass spectrometry (MS) has the potential to directly authenticate protein products, including specific proteoform claims. The development of …

Impact Of Fermented And Non-Fermented Plant-Based Foods Supplementation On Gut Microbiota And Metabolites In C57bl/6j Mice, Priya Darshan Gandhi
Masters Theses
Plant-based proteins have gained popularity because of their high nutritional value and more sustainable alternative to animal-based proteins. Soybean and chickpea are two widely consumed plant-based proteins, whereas tempeh is a popular plant-based fermented whole food product that is rich in protein. With the increase in the development of plant-based food products, there is little research into how plant proteins affect gut microbiota characteristics and metabolites. Therefore, there is a need to understand the underlying mechanisms surrounding the consumption of these foods. The purpose of this study was to investigate the health benefits of soybean, chickpea, and their tempeh counterparts’ …

Valorisation Of Underutilised Dairy Waste Residues: Production Of Lactic Acid Through Microbial Fermentation, Chatan Rai Surana
ORBioM (Open Research BioSciences Meeting)
Annually, approximately 190 million tonnes of liquid waste or co-products is generated by the dairy sector across the globe. These waste streams are nutrient-rich and currently underutilised which gives scope to transform them through microbial fermentation to produce economically valuable products and reduce their negative environmental impact. Such an approach can contribute to the circular bioeconomy by making food production systems more sustainable.
In this study, whey from acid casein hydrolysis (acid whey) and salty whey from Cheddar cheese manufacture were evaluated as feedstocks for production of lactic acid. A total of 466 lactic acid bacteria strains were screened on …

Influence Of Overcooking On Food Digestibility And In Vitro Fermentation, Wensheng Ding
Department of Food Science and Technology: Dissertations, Theses, and Student Research
Areas of char or overcooking commonly appear in foods people consume. It has been reported that overcooked food is harmful to human health. However, little research exists on the effect of overcooking on in vitro protein and starch digestibility and gut microbial fermentation. This study aimed to reveal the connection between overcooking and in vitro protein and starch digestibility and gut microbial fermentation. In vitro protein digestibility of an overcooked ground beef patty was almost half that of a standard cooked sample (27 ± 2% versus 48 ± 6%, respectively; p = 0.02). Whole wheat bread protein digestibility was also …
