Heat Induced Cis/Trans Isomerization In Vegetable Oils And Oleic Acid, John Harwood Scott, Sarah E.G. Porter

Theses & Honors Papers

With the FDA mandating that all foodstuff labels list the amount of trans fates within their product, it becomes necessary to have a rapid and reproducible method for quantifying trans content within foods. Research has led to the advent of an analytical method that utilizes attenuated total reflectance with a Fourier transform infrared spectrometer to quantitatively measure trans fat in foodstuffs. The method is possible because of an infrared absorbance band at 966 cm that is unique to nutritional trans fats. This research used the aforementioned method to quantify trans fat content in common cooking vegetable oils. Before analysis , …

Electromagnetic And Heat Transfer Modeling Of Microwave Heating In Domestic Ovens, Krishnamoorthy Pitchai

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Microwave (MW) ovens are used extensively for heating a variety of not-ready-to-eat food products. It is vital to achieve target temperature uniformly throughout the food to inactivate foodborne pathogens to assure safety. Non-uniform heating of foods in microwave ovens is the major concern in assuring microbiological safety of such products. The non-uniform heating of foods in domestic microwave ovens is due to complex interactions of microwaves with foods. A comprehensive coupled electromagnetic and heat transfer model was developed using finite-difference time-domain based numerical method to understand the complex interaction of microwaves with foods. Simulation parameters such as cell size, heating …

Evaluation And Analysis Of Beef Contamination By Low Levels Of Ammonia, Sely Prajitna

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Leakage of ammonia in food facilities has been known to occur in the past. Ammonia leaks often lead to food contamination in food plants and can cause illness among consumers who accidentally consume the food products contaminated with high levels of ammonia. Therefore, a rapid, simple yet accurate method has to be established for on-site ammonia level screening in food plants to ensure the food is safe. One of the primary objectives in this study was to verify and optimize an ion selective electrode (ISE) method for its accuracy and reproducibility in determining ammonia in meat.

Changes In Dissolved Organic Carbon (Doc) In Arctic Tundra Ponds Over The Past 40 Years, Gabriela Contreras^, Vanessa L. Lougheed*

COURI Symposium Abstracts, Spring 2011

With a warming Arctic, degradation of permafrost is expected to release organic and inorganic materials into aquatic ecosystems; however, there are few long-term datasets with which to test this prediction. The Arctic tundra ponds at the International Biological Program (IBP) site in Barrow, Alaska, studied for the first time in the 1970s, represent one of the very few locations in the Arctic where long-term data are available on freshwater ecosystem structure and function.

Dissolved Organic Carbon (DOC) is used to describe the thousands of dissolved compounds found in water that derive from organic materials. The objective of this study was …

Angiostatin Like Peptides In Milk: Potential Development For Dairy Products Capable Of Cancer Prevention, Erin Stefanutti

Master's Theses

For the past 40 years, antiangiogenic approaches have been of major interest in the development of methods to cure and prevent cancer. Angiogenesis, the development of blood vessels from pre-existing vascularization, is essential for cancer growth and spread of metastasis through the delivery of nutrients and oxygen essential to sustain the metabolic activity of these malignant cells. Blocking access to blood will cause cancerous cells to assume a dormant state creating inactive micro-tumors innocuous to the host. Angiostatin, the internal fragment of the fibrinolytic zymogen plasminogen, has shown great potential in reducing cancer size and number of metastatic colonies in …

Host-Microbial Symbiosis In The Vertebrate Gastrointestinal Tract And The Lactobacillus Reuteri Paradigm, Jens Walter, Robert A. Britton, Stefan Roos

Department of Food Science and Technology: Faculty Publications

Vertebrates engage in symbiotic associations with vast and complex microbial communities that colonize their gastrointestinal tracts. Recent advances have provided mechanistic insight into the important contributions of the gut microbiome to vertebrate biology, but questions remain about the evolutionary processes that have shaped symbiotic interactions in the gut and the consequences that arise for both the microbes and the host. Here we discuss the biological principles that underlie microbial symbiosis in the vertebrate gut and the potential of the development of mutualism. We then review phylogenetic and experimental studies on the vertebrate symbiont Lactobacillus reuteri that have provided novel insight …

Characterization Of Igg And Ige Binding To Parvalbumin Derived From Commercially Important Fish Species, P. Lee, Julie A. Nordlee, S. J. Koppelman, J. L. Baumert, Steve L. Taylor

Department of Food Science and Technology: Faculty Publications

Rationale: Parvalbumin is recognized as pan-allergen in fish and frog. However, previous studies demonstrated that the IgE- and IgG-binding patterns to parvalbumins vary depending on the fish species. We aimed to use 3 anti-parvalbumin IgG and human IgE to investigate the contributing factors for the binding differences.

Methods: Indirect enzyme-linked immunosorbent assay (ELISA) and IgG immunoblotting were used to determine the reactivity of the polyclonal anti-cod parvalbumin antibody and the commercially available, monoclonal anti-frog and anti-carp parvalbumin antibodies against raw muscle extracts of 25 fish species. Additionally, sera from 46 individuals with clinical history of fish allergy were analyzed for …
