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 …

Advancing Agroecological Agroforestry: A Vermont Participatory Storytelling And Story Mapping Project, Sydney Blume

Food Systems Master's Project Reports

Agroforestry is the intentional integration of trees into agricultural landscapes. Advancing agroforestry has the potential to support just food system transition, but it must take direction from traditional approaches (culturally-embedded, millennia-old agroforestry practices in forest ecosystems) and agroecology (the movement, science, and practice for just and sustainable food and agricultural systems). An agroecological approach to agroforestry is essential to avoid agroforestry replicating the logics and harms of industrial agriculture and to encourage learning from traditional agroforestry practices, and likewise, traditional approaches to agroforestry can support a transformative agroecological transition through redesign of agroecosystems and shifting perspectives and ethics. This paper …

Effects Of Cognitive Style On Food Perception And Eating Behavior, Thadeus Lyndon Beekman

Graduate Theses and Dissertations

Within the fields of psychology, notably cultural psychology, the analytic-holistic cognitive style theory has been introduced, developed, fine-tuned, and validated across a wide range of situations, stimuli, and populations. This research, combined with recent applications of the analytic-holistic theory, suggests that the differences in analytic or holistic tendencies of individuals in food, sensory, and consumer tests can impact food perception and associated behaviors. This dissertation aimed to investigate the impact of analytic-holistic cognitive styles of consumers in food situations. The first objective to accomplish this goal was to conduct exploratory research to identify if and where the analytic-holistic theory may …

The Impact Of Dietary Protein Supplementation As Part Of A Time Restricted Feeding Eating Pattern On Sleep, Mood, And Body Composition In Adults With Overweight Or Obesity, Rebecca L. Bowie

Graduate Theses and Dissertations

Obesity in the United States continues to increase, and effective, long-term weight loss strategies are limited. Time restricted feeding (TRF) is a dietary intervention that has potential to serve as an effective long-term weight loss strategy, however more data is needed to establish the effectiveness of a TRF eating pattern on obesity and its related health outcomes. To our knowledge, manipulation of macronutrient composition during TRF intervention and the effect of TRF on sleep and mood have not been studied. Therefore, the objective of this study was to determine the effect of protein supplementation during TRF on mood, sleep, and …

Measuring Palatability As A Linear Combination Of Nutrient Levels In Food Items, Jeffrey S. Young

Faculty & Staff Research and Creative Activity

It well known that palatability and nutritional quality of foods and/or diets are viewed as being in tension with one another. While there exist multiple measures of healthiness, there are no such measures for tastiness. This gap limits the degree to which researchers can investigate this tension and its implications for dietary behavior and hence public health and nutrition policy. The scope of future work concerning the dietary behavior of Americans would expand greatly if researchers better understood consumers’ willingness to eat certain foods, which matters as much as recommending those foods for them to eat in the first place. …

Assessment Of Grain Safety In Developing Nations, Jose R. Mendoza

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

Grains are the most widely consumed foods worldwide, with maize (Zea mays) being frequently consumed in developing countries where it feeds approximately 900 million people under the poverty line of 2 USD per day. While grain handling practices are acceptable in most developed nations, many developing nations still face challenges such as inadequate field management, drying, and storage. Faulty grain handling along with unavoidably humid climates result in recurrent fungal growth and spoilage, which compromises both the end-quality and safety of the harvest. This becomes particularly problematic where there is little awareness about health risks associated with poor …

Feeding The Future Meat Doesn’T Come Cheap, Lukas C. Southard

Capstones

Cultured – or as it is referred to by companies innovating the technology clean – meat is expected to be the next innovation to change the way the world gets its animal protein. Meat from animal cells grown in a lab seems like science fiction but it is around the corner from hitting your supermarket shelves. The technology has been developed but how these companies intend on scaling up their production to meet retail demands remains a mystery. So far companies have relied on seed and early stage investment from venture capital companies and private sources to fund research. Predictions …

What Is The Taste Of Co2? The Sustainability Of Icelandic Food Systems In The Face Of Climate Change, Molly Peek

Independent Study Project (ISP) Collection

Food security in the arctic and subarctic is an area of growing research and concern as climate change continues to alter the availability of traditional foods eaten in remote areas, especially as shipping food has questionable sustainability and contributes to rising CO2 levels. Previous research has noted changes in the Icelandic diet making it more reliant on foreign imports, although there is still strong localized agriculture. Because of its geothermal activity, Iceland has a unique advantage over other highlatitude countries in growing food with a minimal carbon footprint, although that potential is unequal throughout the country. This study utilized available …
