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 …

Upcycling Imperfect Broccoli And Carrot To Healthy Snacks Using An Innovative 3d Food Printing Approach, Taylor Clary

Food Science Undergraduate Honors Theses

Vegetables are healthy foods with nutritional benefits; however, nearly one-third of the world’s fruits and vegetables are lost each year. The losses have the same nutritional value as an acceptable vegetable but have odd shapes or blemishes that make them unsuitable to consumers. 3D technology has numerous capabilities in the automotive, healthcare, and, now, food industries. Within the food industry, 3D food printing can bring customization to product design and nutrition as well as other advancements, including decreasing food waste. In this study, imperfect vegetables (i.e., broccoli and carrot) were upcycled into freeze-dried powders to improve their shelf-life before they …

Characterization Of Jasmine Rice Cultivars Grown In The United States, Anastasia Mills

Food Science Undergraduate Honors Theses

Jasmine rice from Thailand accounts for about 60-70% of U.S. imported rice, primarily due to its preference by ethnic Asians as well as general American population. Recently new U.S. jasmine rice cultivars have been developed independently at three rice research stations in Arkansas, California, and Louisiana, but their properties have not been characterized. The objective of this research was to characterize and compare the physical appearance, chemical composition, thermal and pasting properties, cooked rice texture and starch structures of the newly-developed U.S. jasmine rice from Arkansas, California and Louisiana, to be compared with jasmine rice samples from Thailand. In general, …

Concentration Of Hot Water Extracts Of Anthocyanins Obtained From Muscadine Grape Pomace Using Membrane-Osmotic Distillation, Chuqiao Mai

Food Science Undergraduate Honors Theses

Anthocyanins are well known for their health-promoting benefits. The goal of this study was to evaluate a distillation-based membrane technology to concentrate aqueous anthocyanins extracted from muscadine grape pomace using polypropylene (PP) or ethylene chlorotrifluoroethylene (ECTFE) membranes. A hot water extraction method was utilized to extract the anthocyanins from the pomace. A pre-experimental run using DI water as feed was conducted to optimize the NaCl brine concentration for osmotic distillation and it was determined that 4M was the optimal concentration. The aqueous anthocyanins extraction was filtrated through a series of filter of different pore sizes before the distillation process. Membrane …
