Development Of An Intact Mass Spectrometry Method For The Detection And Differentiation Of Major Bovine Milk Proteins, Emily F. Harley-Dowell
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 …

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 …

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 …

Rice prices in Asia increased since the Summer of 2022 mainly due to worries about a reduction in rice production in India caused by an abnormal monsoon season (Fig. 1). The upward trend in export prices solidified after India implemented a 20% export tariff on brown and milled long-grain rice, and a complete ban on exports of broken rice, in September 2022 to curve down exports and release the pressure on domestic rice prices. India’s rice export prices increased since then and proportionally to the value of the export tax. The latest estimates put rice production at 128 million metric …
Does Caffeine Consumption Affect Work Performance Across Different Job Types?, Bryan Js Goh, Joshua Tan, Cleavon Chong, Sean Ker
Does Caffeine Consumption Affect Work Performance Across Different Job Types?, Bryan Js Goh, Joshua Tan, Cleavon Chong, Sean Ker
Introduction to Research Methods RSCH 202
We propose executing a panel series case study for a large organization in Singapore over a year to examine how caffeine impacts work performance across different job types. Our research question is how does caffeine affect work performance under different conditions due to work type differences. Our dependent variable would be work performance as measured by employees’ Key Performance Indicators (KPIs). We propose to gather data for two of our important independent variables: caffeine use through a recorded pantry system and average sleep hours from a survey. We will analyze the data by using two-factor ANOVA with replication to find …
Optimizing Soil Nutrient Management To Improve Dry Edible Bean Yield And Protein Quality, Emily Jundt
Optimizing Soil Nutrient Management To Improve Dry Edible Bean Yield And Protein Quality, Emily Jundt
Department of Food Science and Technology: Dissertations, Theses, and Student Research
Soil nutrient management is of the utmost importance to ensure crop yields are maximized to feed the world’s growing population. Micro and macronutrient deficiencies can be detrimental to plant growth and cause a drastic reduction in yield. Optimization of nutrient management needs extensive research. Nutrients such as nitrogen increase crop yield, even in legumes capable of using a large amount of nitrogen (N) via biological N fixation. Iron (Fe) fertilizers are also crucial for legumes as they are susceptible to Fe deficiency induced chlorosis.
Dry edible beans (Phaseolus vulgaris) are leguminous plants and excellent dietary protein sources. Great …

Although traditional ryegrass pastures are still commonly used, they require intense management and input and do not perform well during the summer months. Multispecies systems have been recognised as more sustainable, needing less fertiliser and being tolerant to drought and heat. While data on monoculture system fat composition exist, information for multispecies is scarce. The present study compared the fatty acid (FA), carotenoid and fat-soluble composition of a multispecies system (consisting of perennial ryegrass, timothy, white clover, red clover, chicory and plantain) (MULTI) with two other conventional grazing systems (monoculture perennial ryegrass (PRG) and a binary mixture of perennial ryegrass …

Background:Withania somnifera (L.) Dunal, popularly known as Ashwagandha, is an ethnomedicinal plant with multiple pharmacotherapeutic applications. The diverse medicinal properties of the plant are largely due to the presence of withanolides, a group of C28 ergostane based steroidal lactones, with several sites of unsaturation and oxygenation. Withaferin A, a major with anolide present in Ashwagandha plant accounts for its emerging new roles to treat cancer, arthritis, inflammatory responses, immunomodulatory properties, and neuronal disorders. The root and leaf extracts are specifically important constituent materials for the development of phytotherapeutics, mostly intended for oral consumption. Several studies have been carried out …
