Dissertations, Theses, & Student Research in Food Science and Technology
Candida albicans is a dormant commensal in the mucosa of healthy individuals but can become an opportunistic pathogen when the host microflora is compromised. It has been reported as the most common cause of fungal infection among hospitalized U.S. patients, with elevated mortality rate. Candida species have been reported as resistant to antifungal drugs that increase the application of novel strategies to treat this infection. Among the natural compounds that have most gained attention as potential agents against fungi are phenolic compounds against fungi. C. albicans has the ability to switch phenotype from yeast-to-hyphae cells, with hyphae being the ...
Ecofeminism In The Speculative Fiction Of Ursula K. Le Guin, Octavia Butler, And Margaret Atwood, 2018 University of Connecticut
Ecofeminism In The Speculative Fiction Of Ursula K. Le Guin, Octavia Butler, And Margaret Atwood, Cara Williams
Honors Scholar Theses
The aim of this article is to explore the speculative fiction works of three prominent, female speculative fiction writers: Ursula K. Le Guin, Margaret Atwood,and Octavia Butler through an ecofeminist lens. Ecofeminism, as first coined by Francois D'Eaubonne in 1974, is a philosophy that compares the oppression and abuse of women to that of the environment. This article notes how Le Guin, Atwood, and Butler portray women and the environment in post-apocalyptic science fiction. Specifically, this article looks at how these authors explore food acquisition and consumption in their various worlds. This article asks the question, how does ...

Mechanical Engineering Publications
In foods, high levels of biogenic amines (BA) are the result of microbial metabolism that could be affected by temperatures and storage conditions. Thus, the level of BA is commonly used as an indicator of food safety and quality. This manuscript outlines the development of laser scribed graphene electrodes, with locally sourced materials, for reagent-free food safety biosensing. To fabricate the biosensors, the graphene surface was functionalized with copper microparticles and diamine oxidase, purchased from a local supermarket; and then compared to biosensors fabricated with analytical grade materials. The amperometric biosensor exhibits good electrochemical performance, with an average histamine sensitivity ...
Sowing The Seeds Of Skepticism: Russian State News And Anti-Gmo Sentiment, Shawn F. Dorius, Carolyn J. Lawrence-Dill
Biotech news coverage in English-language Russian media fits the profile of the Russian information warfare strategy described in recent military reports. This raises the question of whether Russia views the dissemination of anti-GMO information as just one of many divisive issues it can exploit as part of its information war, or if GMOs serve more expansive disruptive purposes. Distinctive patterns in Russian news provide evidence of a coordinated information campaign that could turn public opinion against genetic engineering. The recent branding of Russian agriculture as the ecologically clean alternative to genetically engineered foods is suggestive of an economic motive behind ...
Ethanol Production By Soy Fiber Treatment And Simultaneous Saccharification And Co-Fermentation In An Integrated Corn-Soy Biorefinery, Jasreen K. Sekhon, Devin Maurer, Tong Wang, Stéphanie Jung, Kurt A. Rosentrater
Food Science and Human Nutrition Publications
Insoluble fiber (IF) recovered from the enzyme-assisted aqueous extraction process (EAEP) of soybeans is a fraction rich in carbohydrates and proteins. It can be used to enhance ethanol production in an integrated corn-soy biorefinery, which combines EAEP with traditional corn-based ethanol processing. The present study evaluated IF as a substrate for ethanol production. The effects of treatment of IF (soaking in aqueous ammonia (SAA), liquid hot water (LHW), and enzymatic hydrolysis), primarily simultaneous saccharification and co-fermentation (SSCF), as well as scaling up (250 mL to 60 L) on ethanol production from IF alone or a corn and IF slurry were ...
Characterization And Mechanisms Of Anthocyanin Degradation And Stabilization, 2017 University of Arkansas, Fayetteville
Characterization And Mechanisms Of Anthocyanin Degradation And Stabilization, Nathan Blaine Stebbins
Theses and Dissertations
Anthocyanins (ACYs) are polyphenol compounds found in nature, which contribute vivid colors to many fruits and vegetables, while also possessing significant health benefits. These pigments range in color from orange-red to blue-violet and could serve as natural colorants to replace artificial additives. There is a great demand from consumers to have fewer artificial compounds in their foods. However, the relatively instability of ACYs must be further understood in order to limit color degradation before they can completely replace synthetic colorants.
ACYs slowly degrade over time, but there is a knowledge gap on their fate and mechanisms causing degradation. In order ...
Experimental Approaches To Understand And Control Salmonella Infection In Poultry, 2017 University of Arkansas, Fayetteville
Experimental Approaches To Understand And Control Salmonella Infection In Poultry, Yichao Yang
Theses and Dissertations
Salmonella is a major foodborne pathogen around the world and chickens are the major reservoir to transmit Salmonella into the human food chain. For decreasing the infection of Salmonella, we developed six attenuated live vaccines based on Salmonella Enteritidis (SE) and Typhimurium (ST) for testing the cross-serovar and cross-serogroup protection from the challenge of Salmonella Heidelberg and Campylobacter jejuni. One of the constructed vaccine strain showed ability to protect against challenge from Salmonella Heidelberg. Even though some preventive approaches are able to decrease Salmonella colonization in the gastrointestinal tract of chickens or other farm animals, Salmonella transmission mechanisms remain unclear ...
A Comparative Life Cycle Assessment Of Nutritionally Equivalent Meals With And Without Pork, 2017 University of Arkansas, Fayetteville
A Comparative Life Cycle Assessment Of Nutritionally Equivalent Meals With And Without Pork, Kelli Young
Theses and Dissertations
The following report details a life cycle assessment of several dietary and meal scenarios with and without pork. The goal of the LCA was to identify the impacts of greenhouse gas emissions, water use, and land use of pork containing and porkless diets and meal plans in a field-to-fork analysis. The dietary and meal plan scenarios are iso-caloric meaning they contain the same number of calories. The first set of diets is based on a USDA consumption pattern, 2000 kcal per day. This diet was used to create three other dietary scenarios with and without pork. The USDA recommended food ...

The Gmo/Ge Debate, Joanna K. Sax
Texas A&M Law Review
We live longer and healthier lives because advances in science create easier and better ways to sustain and survive. Society has an intricate relationship with biotechnology. Vaccines save lives. Fluoridated water decreases dental issues. Antibiotics treat bacterial infections. Nuclear power is a form of clean energy. With any emerging technology, the benefits do not exist in a vacuum, thus, negative consequences result as well. Our widespread uses of antibiotics are creating antibiotic-resistant strains of bacteria. Our research into nuclear energy also facilitated the creation of nuclear bombs. Perhaps it is human nature to use scientific advances for good and for ...
Recognizing Challenges And Opportunities In The Quest To End Hunger, 2017 Texas A&M University School of Law
Recognizing Challenges And Opportunities In The Quest To End Hunger, Jennifer Williams Zwagerman
Texas A&M Law Review
As an attorney and professor that does not focus on intellectual property law, I was a bit apprehensive about providing a keynote address for a Symposium focusing on “Agriculture, Intellectual Property, and Feeding the World in the 21st Century.” As I thought about this topic, knowing that there were other speakers who would focus more on the IP issues and technical aspects of various topics, I kept coming back to the importance of technology as we worktowards the goal of feeding the world, and the many ways in which innovation plays a role in meeting that goal. It also brought ...

Adapting To The Changing World Of Biotechnology: Syngenta Ag Mir162 Corn Litigation As Regulation By Litigation, Paul Goeringer
Texas A&M Law Review
Agriculture has relied on plant breeding to improve genetics since the first domestication of agricultural plants 10,000 years ago. More recently, Gregor Mendel and his hybridization experiments on peas led to what we know as modern genetics. The rise in recombinantDNA technology has opened up many possibilities in plant breeding, including Roundup Ready technology and crop varieties designed to resist a number of pests. At the same time, governments and the private sector have sought to institute regulations for handling the releases of new biotechnology to ensure the technologies will have limited environmental impacts and provide safe foods to ...
Application Of X-Ray Imaging As A Technique For Fissure Detection In Rough Rice Kernels, 2017 University of Arkansas, Fayetteville
Application Of X-Ray Imaging As A Technique For Fissure Detection In Rough Rice Kernels, Zephania R. Odek
Theses and Dissertations
Fissured rice kernels break during milling, leading to head rice yield (HRY) reductions. Conventional fissure detection instruments cannot be used to observe fissures in rough rice kernels, the form in which rice in normally dried and stored. X-rays can penetrate hulls allowing visualization of the internal structure of a rough rice kernel. This study evaluated the capability of X-ray imaging to adequately detect fissures in rough rice and established a correlation between HRY and the fissured kernel percentage (FKP) in a rough rice sample. Fifteen long-grain rice cultivars, harvested in Arkansas in 2015 and 2016 were dried using heated air ...
Weird Science: Frankenstein Foods And States As Laboratories Of Democracy, 2017 Cleveland-Marshall College of Law, Cleveland State University
Weird Science: Frankenstein Foods And States As Laboratories Of Democracy, Jennifer Mcgee
Journal of Law and Health
The National Bioengineered Food Disclosure Standard (the 'National Standard') was signed into law July 29, 2016. This Article analyzes the National Standard and posits that Vermont’s Act 120 was a more effective labeling law because it safeguarded consumer sovereignty. The State regulatory scheme in place prior to the passage of the National Standard satisfied consumer demand for disclosure while allowing for necessary experimentation with GMO labeling. Part I provides an overview of the current federal scheme regulating GMOs. Part II analyzes of the conflict surrounding GMOs and labeling. Given that analysis, Part III compares the disclosure requirement of the ...
Formulation, Characterisation And Stability Assessment Of A Food Derived 1 Tripeptide, Leucine-Lysine-Proline Loaded Chitosan Nanoparticles, 2017 Dublin Institute of Technology
Formulation, Characterisation And Stability Assessment Of A Food Derived 1 Tripeptide, Leucine-Lysine-Proline Loaded Chitosan Nanoparticles, M.K. Danish, Giuliana Vozza, Hugh Byrne, Jesus Frias, Sinead Ryan
The chicken or fish derived tripeptide, Leucine-Lysine-Proline (LKP), inhibits the Angiotensin Converting Enzyme and may be used as an alternative treatment for pre-hypertension. However, it has low permeation across the small intestine. The formulation of LKP into a nanoparticle (NP) has the potential to address this issue. LKP-loaded NPs were produced using an ionotropic gelation technique, using chitosan (CL113). Following optimisation of unloaded NPs, a mixture amount design was constructed using variable concentration of CL113 and tripolyphosphate at a fixed LKP concentration. Resultant particle sizes ranged from 120-271 nm, zeta potential values from 29-37 mV and polydispersity values from 0 ...
The Recovery Of Protein From Egg Yolk Protein Extraction Granule Byprouct, 2017 California Polytechnic State University, San Luis Obispo
The Recovery Of Protein From Egg Yolk Protein Extraction Granule Byprouct, Irene Jennifer Kaufman
Master's Theses and Project Reports
In addition to proving an excellent source of nutrients, eggs are used in the food, cosmetic, and biotechnology industries for their rheological and bioactive properties. Much of the potential for the added value is in individual components of the egg, rather than the whole egg. At low speed centrifugation, yolk separates into two distinct fractions—granules and plasma. It is becoming increasingly popular in the industry to remove the plasma fraction of the egg yolk to use for its livetins, particularly immunoglobulin Y, leaving behind a granule by-product (“yellow cake”). Previous research has shown potential added-value from the granule fraction ...

Postharvest Quality And Physiology Of ‘Fuji’ Apples Subjected To Phytosanitary Irradiation, Nasim Kheshti, Alan Baquero, Anderson Melo, Anuradha Prakash
Student Research Day Abstracts and Posters
Irradiation is an effective treatment to sterilize and destroy insect pests on fresh fruit. It serves as an alternative to cold treatment and to fumigation which are time consuming and ozone depleting, respectively. In this study, the postharvest quality of Fuji apples was evaluated after irradiation at 400 Gy and 800 Gy. The quality of the apples which were stored at 1˚C for 7 days to mimic ground transportation and distribution and then at ambient temperature for another 7 days to mimic retail storage and consumer use, was assessed. Irradiation caused an immediate decrease in firmness by 12% at ...

Identification Of Meat And Poultry Species In Food Products Using Dna Barcoding, Rosalee S. Hellberg, Brenda C. Hernandez, Eduardo L. Hernandez
Food Science Faculty Articles and Research
DNA barcoding is a promising method for the sequencing-based identification of meat and poultry species in food products. However, DNA degradation during processing may limit recovery of the full-length DNA barcode from these foods. The objective of this study was to investigate the ability of DNA barcoding to identify species in meat and poultry products and to compare the results of full-length barcoding (658 bp) and mini-barcoding (127 bp). Sixty meat and poultry products were collected for this study, including deli meats, ground meats, dried meats, and canned meats. Each sample underwent full and mini-barcoding of the cytochrome c oxidase ...

Faculty Publications from the Center for Plant Science Innovation
Soya bean (Glycine max (L.) Merr.) is sought after for both its oil and protein components. Genetic approaches to add value to either component are ongoing efforts in soya bean breeding and molecular biology programmes. The former is the primary vegetable oil consumed in the world. Hence, its primary usage is in direct human consumption. As a means to increase its utility in feed applications, thereby expanding the market of soya bean coproducts, we investigated the simultaneous displacement of marine ingredients in aquafeeds with soya bean-based protein and a high Omega-3 fatty acid soya bean oil, enriched with alpha-linolenic and ...
