Subcritical Water Hydrolysis Of Whey Proteins, Ashley Dawn Espinoza
Subcritical Water Hydrolysis Of Whey Proteins, Ashley Dawn Espinoza
Graduate Theses and Dissertations
Hydrolyzing food by-products is a unique approach to potentially increase by-product value and reduce waste. An abundant by-product of cheese production, whey, contains all essential amino acids and some distinctive peptides with functional and nutraceutical properties. Typically, proteins from whey are tailored for specific uses by chemical or enzymatic hydrolysis; however, subcritical water hydrolysis is a novel alternative used successfully to hydrolyze various substrates. Nevertheless, minimal research exists on: (1) the hydrolysis of whey protein; (2) the incorporation of additives; (3) the hydrolysis of whole whey; and (4) the production of volatiles when using subcritical water hydrolysis.
Therefore, whey protein …

Purchaser Preferences On Carbon Labels: Conventional Vs. Organic Milk, Mustafa Ozkan
Graduate Theses and Dissertations
Over the past several years, there has been growing attention concerning global warming/climate change and how humans are contributors. It is known that agricultural production is a main contributor of greenhouse gas emissions and the livestock sector is particularly significant because it is quoted as having between 3 and 18% of greenhouse gas emissions measured in CO2 equivalent pending different assumptions. Due to this, carbon footprint labeling has been described as a potential tool to inform consumers about greenhouse gases associated with food products and assist them with the necessary information to purchase products that help reduce greenhouse gas emissions. …

Marketing Margins Of Strawberries 2006-2010 Shipping Point-Terminal-Retail Price, Matej Mikle Barat
Graduate Theses and Dissertations
This thesis examines vertical price relationships for fresh strawberries. Specifically, the focus is on three stages of the vertical chain. The first stage is the shipping point. Shipping points represent major strawberry production regions and are the closest price point to the farm. The second stage is the terminal market. Terminal markets are wholesale markets in major US cities. The third stage is the retail level. Retail level prices are measured as average supermarket prices in the same cities for which terminal market prices are available. Using weekly data, markup equations are estimated from upstream to downstream levels of the …

Genetic manipulation of crop plants, through breeding or transgenic approaches, for enhanced tolerance to abiotic stress holds great promise for improving yields and promoting new methods for sustainable agriculture. This study examines the potential role that genes of the soybean, Glycine max L., encoding elongation factor-1 alpha (EF-1α) and glyoxalase I (GlxI) might play in response to salt stress. Previous reports have suggested a possible function for both GlxI and EF-1α in conferring enhanced salt tolerance in other plant species. In addition to other possible mechanisms, salt tolerance in soybeans can be regulated by plant uptake and transport of chloride …

A Novel Gene Silencing Vector For Plant Genomics And Biotechnology, Dustin Hoover, Scott Nicholson, Vibha Srivastava
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Gene silencing is a process of suppressing activity of specific genes by producing “interfering” RNA encoded by foreign genes. This process serves as the principle of genetic modification in plants and animals, which is an important tool in genomics and biotechnology, allowing scientists to manipulate organisms to better meet human demands. New approaches of gene silencing may enable improvements on current practices of genetic modification, and broaden the application and impact of gene silencing in biotechnology. Recently, a novel vector design consisting of the transcription of short gene fragments lacking transcription termination signals was demonstrated to be effective in partial …
