Behavioral Determinants Of Biofortified Food Acceptance: The Case Of Orange-Fleshed Sweet Potato In Ghana, Chinonso E. Etumnu 2016 University of San Francisco

Behavioral Determinants Of Biofortified Food Acceptance: The Case Of Orange-Fleshed Sweet Potato In Ghana, Chinonso E. Etumnu

Master's Theses

Biofortified foods are being introduced in sub-Saharan Africa as an important strategy to help address micronutrient malnutrition. However, there has been little research on factors that could play decisive roles in their successful introduction. This paper investigates the determinants of consumer acceptance of biofortified orange-fleshed sweet potato (OFSP) using data from a choice experiment conducted in Ghana. I find that OFSP is preferred to traditional white-fleshed and yellow-fleshed sweet potatoes as indicated by consumers' marginal willingness to pay for the three varieties. I also find that respondents' socio-economic characteristics do not have a significant effect on consumer acceptance of OFSP ...

Gluten-Free And Casein-Free Dietary Intervention For Children Diagnosed With Autism Spectrum Disorder, Avalon Derlacki 2016 Chapman University

Gluten-Free And Casein-Free Dietary Intervention For Children Diagnosed With Autism Spectrum Disorder, Avalon Derlacki

Student Research Day Abstracts and Posters

In the United States, autism spectrum disorders (ASD) had a prevalence of 1 in 150 children in 2000. In the year 2012, the prevalence of ASD in the United States jumped to 1 in 68 children (Centers of Disease Control and Prevention, 2012). Due to the increase in diagnoses of ASD, researchers have sought out different ways to help decrease maladaptive symptoms associated with ASD’s. Many parents of children diagnosed with ASD administer a gluten-free and casein-free (GFCF) diet to their children in hopes of reducing their maladaptive symptoms. The project hypothesis states that if a child under the ...

Scaling Up Fruit And Vegetable Production: Is Machinery Sharing A Possibility?, Georgeanne M. Artz, Linda Naeve

Georgeanne Artz

Abstract

Interest in local food is growing among consumers and small-scale farmers, as evidenced by the significant increase in the number of farmers’ markets, community-supported agriculture arrangements, and food hubs, in the last ten years. To meet the demand for locally grown fruits and vegetables, many small-scale farmers are considering scaling up their production. However, to remain profitable they need to balance production with increased labor costs and the need for specialized machinery. A study conducted in Iowa worked with five groups of farmers who shared different pieces of machinery. With help from the researchers, they developed sharing agreements and ...

Genetic Diversity In Concentration Of A Protein Subcomponent In Selected Wheat Lines, Andrew B. Berman, Kelsey Gentry, Alexander K. Lee, Molly Yandrofski, Malorie Young, Robert L. Paris

The Research and Scholarship Symposium

Celiac Disease is a hypersensitive response to gluten caused by HLA-DQ2 or HLA-DQ8 T-cell presentation, initiating destruction of intestinal epithelial cells. Studies indicate that an indigestible fragment of the gluten molecule, alpha-gliadin subcomponent 33-mer, rich in proline and glutamine, is responsible for the hypersensitivity response. Determination of 33 mer concentration in wheat lines would be beneficial to future development of wheat lines with reduced 33 mer concentration. Protein from wheat flour was extracted and subjected to western blot in order to quantify the concentration of 33-mer. This will be a valuable tool for future research efforts focused on identification and ...

Improving The Utilization Of Dry Edible Beans In A Ready-To-Eat Snack Product By Extrusion Cooking, Franklin Sumargo

Dissertations & Theses in Food Science and Technology

The growing snacking habit and steady increasing demand for healthy snacks have drastically changed the ready-to-eat snack market in recent years. While the current healthy, ready-to-eat snack products are still dominated by whole cereal grains, legumes, especially dry edible beans, have a high potential to emerge in nutritional, novel food. Dry edible beans (Phaseolus Vulgaris L) are not only economically valuable but also nutritionally important, since they are important sources of proteins, B vitamins, mineral elements, and soluble dietary fibers even when compared to whole grain cereals. Recent studies have shown extrusion processing is not only effective at producing an ...

The Archaeology Of Appetites, Molly S. Schonert

SEWSA 2016 Intersectionality in the New Millennium: An Assessment of Culture, Power, and Society

Through use of examining how food is produced, stored, distributed and consumed, one can take a glimpse into the past, present and even future of this planet–to better understand the complexity of human identity and the social practices or roles that define an individual, community or society. So this begins an exploration of the archaeology of food as a gendered commodity throughout our evolutionary past, emphasizing the infinite ways in which foodway practices exceeds the nutritional value of what our ancestors, family, friends and ourselves consume(d) on a daily basis. Foodways practices is an invaluable tool in any ...

Reducing The Potential For Acrylamide Formation In Wheat Products, Amy Hauver, P. Stephen Baenziger, Mary J. Guttieri

UCARE Research Products

Acrylamide, a chemical formed from free asparagine and reducing sugars during high-temperature cooking via the Maillard reaction (i.e. frying or baking) of high starch foods is deemed ‘probably carcinogenic to humans’ based on its affect in mice. In April of 2002, a group of Swedish researchers reported findings that presented evidence that heat-treated, starch-rich foods contained high levels of acrylamide, later linking the production of acrylamide to the Maillard reaction. A number of other studies have been done to link dietary intake of acrylamide to human cancers and other health effects, although many have had inconclusive results. Nevertheless, the ...


Identification Of Sporeforming Bacteria In The Milk Chain And Its Potential Sources In Farm Environment, Bismarck Antonio Martinez 2016 University of Nebraska-Lincoln

Identification Of Sporeforming Bacteria In The Milk Chain And Its Potential Sources In Farm Environment, Bismarck Antonio Martinez

Dissertations & Theses in Food Science and Technology

The dairy industry is recently facing a quality problem due to the presence of sporeformer bacteria in different products. These bacteria are members mainly of the Bacillus taxonomic group and due to their abilities to survive pasteurization, can not be controlled by this process technology. Consequently, this bacteria population affects the quality of some products during storage (e.g. fluid milk) and limit their potential markets (e.g. milk powder). Since no technology/interventions are currently available to eliminate this bacteria type once they enter the milk chain, the identification of their entry points and sources is essential information to ...
