Department of Food Science and Technology: Faculty Publications

Electrodialysis with bipolar membrane (EDBM) is promising to recover phospholipids (PLs) from sweet whey and whey protein concentrate (WPC), as it promotes lipoprotein complex formation following a decrease in pH and ionic strength. The aim of this work was to study the impact of dilution factor (without dilution, with a 2X, 4X and 6X dilution) after EDBM on the process performances. For both products, a 4X dilution, which cor- responds to a decrease in ionic strength of 81.4 ± 1.5 % for sweet whey and 79.4 ± 0.4 % for WPC, seemed sufficient to maximize lipoprotein complex formation as a …

Background: There is increasing interest in the use of eliciting doses (EDs) to inform allergen risk management. The ED can be estimated from the distribution of threshold doses for allergic subjects undergoing food challenges within a specified population. Estimated ED₀₅ values for cow's milk (the dose expected to cause objective allergic symptoms in 5% of the milk-allergic population) range from 0.5 mg to 13.9 mg cow's milk protein. We undertook a single-dose challenge study to validate a predicted ED₀₅ for cow's milk of 0.5 mg protein.

Methods: Participants were recruited from 4 clinical centres. Predetermined criteria were used …

Egg Replacements In Vegan Cookies, Haley Bryant, Ben Declue

2021 Research Posters

Researchers tested several vegan egg replacements in cookies to find one that resulted in product most similar to a cookie with eggs. It was hypothesized that flaxseed would be the best overall scoring egg replacement for vegan, egg-free chocolate chip cookies. Each egg replacement was tested in a controlled environment while recording the times and temperatures of each baking trial. The flaxseed egg replacement cookie scored closest to the control cookie after being evaluated.

Acceptability Of Low-Carb Pizza Crust, Sara Hasty, Megan Karlie

2021 Research Posters

Diabetes is a chronic disease that affects how the body turns food into useable energy. This public health issue has been growing worldwide. In 2014 the WHO stated 422 million adults had diabetes and 1.6 million deaths are caused by diabetes each year.

The purpose of this study was to create a completely low-carb alternative to a conventional pizza crust, lower the sugars/carbs, provide nutritional value, and still produce an acceptable and palatable result. The hypothesis of the experiment is that by replacing all-purpose flour and granulated sugar with almond flour and a vegetable, a pizza crust can be made …

Unprocessed Vegan Brownies, Mckenzie Derennaux, Georgie Menzel

2021 Research Posters

The goal was to make a vegan brownie that was an unprocessed version of our control, and that is just as enjoyable, if not more enjoyable, than a traditional brownie.

The target population is people who want to live a whole food driven diet, those who are plant-based, and for those who have high cholesterol and heart disease.

The ingredients of the unprocessed vegan brownies are more whole-food and plant-based, with zero added sugar, less salt, and no cholesterol.

Due to time restraints for trials within the study the researchers feel that the goal was not met in the four …

Reducing Fat In Alfredo Sauce Recipes, Claire Dalton, Alison Griffith

2021 Research Posters

The Standard American Diet includes high intakes of processed foods and saturated fat. The Standard American Diet has been implicated in contributing to the health challenges experienced in the United States such as obesity and chronic pain. The goal of this experiment is to reduce the fat content of cream sauce and receive similar scores among a group of panelists/taste testers in flavor, texture, appearance, and overall likeability to a full fat sauce. The results showed that although the scores of the low-fat recipes were not as high as the full fat recipe, a close alternative was found while reducing …

Baseline Sensitivity To Demethylation Inhibitors Fungicides In Cercospora Spp. And Corynespora Spp. In Arkansas Soybeans, Evan Buckner, Alejandro Rojas

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Cercospora spp. and Corynespora spp. are two common foliar fungal pathogens in Arkansas and other soybean-producing areas. Two primary diseases caused by Cercospora spp. are Cercospora Leaf Blight (CLB, caused mainly by C. kikuchii) and Frogeye Leaf Spot (C. sojina). Over time, many fungicides used to combat these diseases have become ineffective as the pathogens have developed a resistance to them. The class of the fungicide in question is Triazoles [Demethylation Inhibitors (DMI)–FRAC 3]. Fifteen isolates consisting of Corynespora cassiicola, Cercospora sojina, and Cercospora flagellaris were tested to determine baseline sensitivities using serial dilutions (0, 0.01, 1, 10, 50 mg/L) …

Whey protein isolate supplementation has been recognized as having potential for regulating appetite, thereby potentially improving mood and food intake. The objectives of this project were to 1) analyze the effects of high-quality whey protein intake on overall diet and 2) identify and examine a correlation between tryptophan levels and mood regulation. This research was conducted using a randomized experimental design. A total of 13 postmenopausal women (12+ months after last reported menstrual cycle) were recruited and allocated to one of two dietary intervention (DI) groups: 1) control (maintain current lifestyle; CON; n = 6), and 2) whey protein isolate …

Procuring Produce In A Rural, Appalachian County: A Thematic Analysis Of Community Member Experiences, Caroline Blincoe

Theses and Dissertations--Nutrition and Food Systems

Rates of obesity and other health disparities are exceptionally high in rural Appalachian counties compared to the nation as a whole. One causal factor of these health disparities in Appalachian counties is the inequitable allocation of healthy food. Food insecurity and the local food environment are large drivers for obesity experienced by Martin County, Kentucky residents. Successful socioecological model (SEM) and policy, systems, and environmental (PSE) interventions have shown promising results in reducing obesity and enhancing food security in this population. Through the transcription of semi-structured focus group interviews, thematic analysis aimed to obtain perspectives on the local food system. …
