All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Flavor lexicons are used in sensory evaluation to determine the flavor profile of a food product. The objective of this study was to develop a flavor lexicon for cooked beef, which can then be used in various projects relating to beef quality such as studies investigating animal diet, marinating, ageing, or other enhancements. A descriptive panel of 10 people was used to develop a flavor lexicon of 18 attributes, including astringent, barny, bloody, brothy, browned, gamey, grassy, juicy, fatty, livery, metallic, oxidized, roast beef, and the five basic tastes (bitter, salty, sour, sweet, and umami). In contrast to other studies …

Adherence Inhibition Of Cronobacter Sakazakii And Other Pathogens By Prebiotic Oligosaccharides, Plant Extracts, And Other Naturally Derived Molecules, Maria I. Quintero

Department of Food Science and Technology: Dissertations, Theses, and Student Research

For most bacterial pathogens, adherence of the bacterium to the surface of the host cell tissue is a necessary first step for colonization and infection.  Agents that inhibit adherence, therefore, could be useful for preventing infections.  The goal of this research was to assess the anti-adherent activity of several food-grade prebiotic carbohydrates, plant extracts, and other naturally-derived molecules against enteric pathogens. First, the antiadherent effect of galactooligosaccharides (GOS), polydextrose (PDX), and a GOS-PDX blend was tested against two strains of Cronobacter “Enterobacter” sakazakii. When measured microscopically or by cultural methods, significant reductions in adherence (56% and 71%, respectively) of C. …

Heat Induced Cis/Trans Isomerization In Vegetable Oils And Oleic Acid, John Harwood Scott, Sarah E.G. Porter

Theses & Honors Papers

With the FDA mandating that all foodstuff labels list the amount of trans fates within their product, it becomes necessary to have a rapid and reproducible method for quantifying trans content within foods. Research has led to the advent of an analytical method that utilizes attenuated total reflectance with a Fourier transform infrared spectrometer to quantitatively measure trans fat in foodstuffs. The method is possible because of an infrared absorbance band at 966 cm that is unique to nutritional trans fats. This research used the aforementioned method to quantify trans fat content in common cooking vegetable oils. Before analysis , …

White Potatoes, Including French Fries, Contribute Shortfall Nutrients To Children's And Adolescents' Diets, Marjorie Freedman, Debra Keast

Faculty Publications

To test the hypothesis that white potatoes (WP), oven-baked fries (OBF), and french fries (FF) contribute important nutrients within energy needs to children's and adolescents' diets, secondary analysis of 24-hour dietary recall data from the National Health and Nutrition Examination Survey 2003-2006 was conducted. Potato content of survey foods was determined using US Department of Agriculture recipe databases (Standard Reference (SR)-Link files). Nutrient content of potatoes was determined by linking SR codes to US Department of Agriculture food composition data. Daily nutrient intakes from potatoes were determined by applying the composition database to respondent's recall data. Sample-weighted data were analyzed; …
