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 ...

For most people, a cricket's chirp is the song of summer. But for a multidisciplinary team of Colby alumni, the uninhibited chorus that comes from the insects marks a leap towards the future of sustainable food systems.
Adapting To The Changing World Of Biotechnology: Syngenta Ag Mir162 Corn Litigation As Regulation By Litigation, 2017 Texas A&M University School of Law
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 ...

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 ...
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 ...
Gelatinization Properties Of Starches From Three Successive Generations Of Six Exotic Corn Lines Grown In Two Locations, Y. Ji, L. M. Pollak, S. Duvick, K. Seetharaman, Philip Dixon, Pamela J. White
The objectives of this research were to evaluate the intra- and interpopulation variability in gelatinization properties of starches from exotic corn lines and their derivatives when grown 1) during two successive years in the same location; and 2) in both temperate and tropical environments. Six novel exotic corn lines (two 100% exotic and four 25% exotic derived from a breeding cross developed by crossing an exotic hybrid with Corn Belt lines) were selected for this research because their starches have significantly different (and potentially useful) thermal properties from those found in starch from normal Corn Belt corn. The Sn (n ...
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 ...

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 ...

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 ...

Ozonation Efficacy In The Treatment Of Soil-Borne Phytophthora Sojae In Cultivating Soybeans, Nahed Msayleb, Rameshwar S. Kanwar, Huaiqing Wu, Johannes Van Leeuwen
Agricultural and Biosystems Engineering Publications
Ozonation was studied for inactivating Phytophthora sojae, a predominant soybean pathogen that causes root and stem rot, and pre-and post-emergence soybean damping-off. Typically, fungicides are used to treat soils to control the damage from P. sojae to soybean production. An environmentally friendly method of ozonation was studied for inactivating P. sojae, a model Phytophthora pathogen that affects a wide range of high-value crops. Assays of artificially inoculated soil samples with P. sojae were treated with different doses of gaseous ozone. This study showed that a dosage of 0.47 g.kg-1 O3 in the soil totally prevented root and stem-rot ...
Public Acceptance Of And Benefits From Agricultural Biotechnology: A Key Role For Verifiable Information, 2016 Iowa State University
Public Acceptance Of And Benefits From Agricultural Biotechnology: A Key Role For Verifiable Information, Wallace E. Huffman, Abebayehu Tegene
The on-going genetically modified (GM) food and genetically modified organism (GMO) conaovccsy threaten to destroy the near-term market for agbiotech food and inputs and alter greatly the net social benefits that are potentially attainable from agriculcural biotechnology. For example, consider:
1. In February 2000 Greenpeace filed a lawsuit challenging the US Environmental Protection Agency's decision co allow the release of GM insect resistant (Bt) crops. In their news release they stated 'The EPA should stop [GE] polluters before the environment is threatened' (Greenpeace, 2000a).
2. During the week of 23 March 2000 Greenpeace joined over 50 other organizations in ...
Consumer Demand For Potato Products And Willingness-To-Pay For Low-Acrylamide, Sulfite-Free Fresh Potatoes And Dices: Evidence From Lab Auctions, Katie Lacy, Wallace E. Huffman
We assess consumer demand for traditional fresh potatoes and processed potato products and willingness to pay for new experimental low-acrylamide and sulfite-free potato products. Demand for fresh potatoes, potato chips, and fries is unaffected by household income or education, but demand for chips and fries is affected by consumer age and exercise habits. Subjects display increased willingness to pay for new potato products after receiving a private company perspective about the technology and risks associated with exposure to acrylamide, a carcinogen, in fried conventional potatoes and a new product, potato dices. We find that consumers are willing to pay for ...
An Investigation Into Spent Coffee Waste As A Renewable Source Of Bioactive Compounds And Industrially Important Sugars, 2016 Dublin Institute of Technology
An Investigation Into Spent Coffee Waste As A Renewable Source Of Bioactive Compounds And Industrially Important Sugars, Damhan Scully, Amit Jaiswal, Nissreen Abu-Ghannam
Conventional coffee brewing techniques generate vast quantities of spent espresso grounds (SEGs) rich in lignocellulose and valuable bioactives. These bioactive compounds can be exploited as a nutraceutical or used in a range of food products, while breakdown of lignocellulose generates metabolizable sugars that can be used for the production of various high-value products such as biofuels, amino acids and enzymes. Response surface methodology (RSM) was used to optimize the enzymatic saccharification of lignocellulose in SEGs following a hydrothermal pretreatment. A maximum reducing sugar yield was obtained at the following optimized hydrolysis conditions: 4.97 g of pretreated SEGs, 120 h ...
Fermentation-Assisted Extraction Of Isothiocyanates From Brassica Vegetable Using Box-Behnken Experimental Design, 2016 Dublin Institute of Technology
Fermentation-Assisted Extraction Of Isothiocyanates From Brassica Vegetable Using Box-Behnken Experimental Design, Amit Jaiswal, Nissreen Abu-Ghannam
Recent studies showed that Brassica vegetables are rich in numerous health-promoting compounds such as carotenoids, polyphenols, flavonoids, and glucosinolates (GLS), as well as isothiocyanates (ITCs) and are involved in health promotion upon consumption. ITCs are breakdown products of GLS, and typically used in the food industry as a food preservative and colouring agent. They are also used in the pharmaceutical industry due to their several pharmacological properties such as antibacterial, antifungal, antiprotozoal, anti-inflammatory, and chemoprotective effects, etc. Due to their widespread application in food and pharmaceuticals, the present study was designed to extract ITCs from York cabbage. In order to ...
