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 …

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 …
An Investigation Of The Impact Of Entrepreneurship Programs On Student Interest In Entrepreneurship Competitions, 2023 Clemson University
An Investigation Of The Impact Of Entrepreneurship Programs On Student Interest In Entrepreneurship Competitions, Toni Sharp
All Theses
According to a survey by ACNielsen International Research, over half of Americans want to start their own business to build wealth and achieve independence (Bygrave & Zacharakis, 2011). In the research community, most entrepreneurship education research happens in business schools (Matlay, 2006). As a result of continually researching one form of entrepreneurship, less attention has been paid to other forms contributing to the “definitional obscurity with important consequences for the direction of the field” of entrepreneurship (Baker & Welter, 2017). This has created a need for research on entrepreneurship at the college level in fields outside of business.

How Does Increasing The Darkness Of A Plate Affect The Perception Of Both Bitter And Sweet Flavors?, 2023 University of Arkansas, Fayetteville
How Does Increasing The Darkness Of A Plate Affect The Perception Of Both Bitter And Sweet Flavors?, Jessica Williams
Food Science Undergraduate Honors Theses
Extrinsic cues like plate color have been shown to effect taste perception. Previous studies conducted show a consensus that plate colors can modulate taste perception (Piqueras-Fizman et al., 2012, Stewart & Gross, 2013). No studies, however, have investigated varying color hues and their effect on taste perception. This study aims to determine whether the change in the black to white ratio of plate color can affect consumer perception of sweetness or bitterness.
We presented a group of volunteers two different brownies on plates varying from 100% white to 0% white in 25% increments. A 30:70 male to female gender ratio …

Hydrolysis Of Chlorogenic Acid In Sunflower Flour Increases Consumer Acceptability Of Sunflower Flour Cookies By Improving Cookie Color, Christine Lo Verde, Criselda Toto Pacioles, Natalie Paterson, Jamie Chin, Cedric P. Owens, Lilian W. Senger
Food Science Faculty Articles and Research
Sunflower meal, a byproduct of sunflower oil pressing, is not commonly used in alkaline baking applications. This is because chlorogenic acid, the main phenolic antioxidant in sunflower seeds, reacts with protein, giving the baked product a green discoloration. Our group previously demonstrated that a chlorogenic acid esterase from Lactobacillus helveticus hydrolyzes chlorogenic acid in sunflower dough cookie formulations, resulting in cookies that were brown instead of green. This study presents a sensory analysis to determine the acceptability of enzymatically upcycled sunflower meal as an alternative protein source for those allergic to meals from legumes or tree nuts. We hypothesized that …
