Characterisation Of Cold Plasma Treated Beef And Dairy Lipids Using Spectroscopic And Chromatographic Methods, Chaitanya Sarangapani, David Dorran, Julie Dunne, Paula Bourke, Patrick Cullen

Articles

The efficacy of cold plasma for inactivation of food-borne pathogens in foods is established. However, insights on cold plasma-food interactions in terms of quality effects, particularly for oils and fats, are sparse. This study evaluated plasma-induced lipid oxidation of model matrices, namely dairy and meat fats. Product characterisation was performed using FTIR, 1H NMR and chromatographic techniques. The oxidation of lipids by cold plasma followed the Criegee mechanism and typical oxidation products identified included ozonides, aldehydes (hexanal, pentenal, nonanal and nonenal) and carboxylic acids (9-oxononanoic acid, octanoic acid, nonanoic acid), along with hydroperoxides (9- and 13-hydroperoxy-octadecadienoylglycerol species). However, these ...

Species And Trichothecene Genotypes Of Fusarium Head Blight Pathogens In Nebraska, Usa In 2015-2016, Esteban Valverde-Bogantes

Dissertations, Theses, & Student Research in Food Science and Technology

Fusarium head blight (FHB) of wheat and other small grain cereals is a devastating and economically important disease caused by members of the Fusarium graminearum species complex (FGSC). FHB poses a threat to food security and food safety, due to yield and quality reduction, as well as mycotoxin contamination. To determine the diversity of species and trichothecene genotypes of the FGSC in Nebraska, 33 wheat samples were collected from FHB-affected fields during two consecutive years (2015 and 2016) and 50 Fusarium isolates were obtained from those wheat samples. Identification of F. graminearum was attempted by PCR using UBC85 and GO ...


Anti-Cancer And Bioavailability Of Arachidin-1 And Arachidin-3 In Colon Cancer Cells, Macy R. Shirley 2017 University of Arkansas- Fayetteville

Anti-Cancer And Bioavailability Of Arachidin-1 And Arachidin-3 In Colon Cancer Cells, Macy R. Shirley

Human Nutrition and Hospitality Innovation Undergraduate Honors Theses

Cancer is a common cause of death in the United States and locally in the state of Arkansas. Modifiable factors such as tobacco use, physical activity, and diet lead to reduced incidence of colon cancer diagnosis. Fruits and vegetables contain phytochemicals that confer health promoting properties. Specifically, peanuts contain phytochemicals known as resveratrol, arachidin-1, and arachidin-3 that have been linked to anticancer activities. However, a few research studies have been done on arachidin-1 and arachidin-3 that could further develop understanding of their health promoting properties or nutraceutical applications. The objectives of this study were to (1) determine the most effective ...


Simulating Foodborne Pathogens In Poultry Production And Processing To Defend Against Intentional Contamination, Silas B. Lankford 2017 University of Arkansas, Fayetteville

Simulating Foodborne Pathogens In Poultry Production And Processing To Defend Against Intentional Contamination, Silas B. Lankford

Computer Science and Computer Engineering Undergraduate Honors Theses

There is a lack of data in recent history of food terrorism attacks, and as such, it is difficult to predict its impact. The food supply industry is one of the most vulnerable industries for terrorist threats while the poultry industry is one of the largest food industries in the United States. A small food terrorism attack against just a single poultry processing center has the potential to affect a much larger population than its immediate consumers. In this work, the spread of foodborne pathogens is simulated in a poultry production and processing system to defend against intentional contamination. An ...

Temporal Evaluation Of Corn Respiration Rates Using Pressure Sensors, Gagandeep Singh Ubhi 2017 University of Arkansas, Fayetteville

Temporal Evaluation Of Corn Respiration Rates Using Pressure Sensors, Gagandeep Singh Ubhi

Theses and Dissertations

High respiration rate of a grain indicates faster degradation of its dry matter. Proper grain management requires chronological and precise measurements of carbon dioxide evolved from grain respiration during the postharvest storage duration. Therefore the main goal of this research was to develop a new technique that evaluates temporal corn respiration rate using pressure sensors. It was based on measuring pressure drop associated with the grain respiration in a closed container and using it to calculate the grain respiration rates.

Dry corn (Zea Mays L.) was procured from a local farmer and stored at 4ºC. Corn rewetting technique was applied ...

This is a report of research progress in this project through early 1995. The results of these initial experiments have led us to propose hypotheses about the patterns of inheritance of aromatic compounds in Agastache foeniculum. We are now testing those hypotheses with larger plant populations. On request, we will be pleased to provide readers with more up-to-date information as we complete the analyses of our ongoing experiments. Until such results are subject to scientific peer review, the data presented in the following report must be considered strictly preliminary.

Journal of Applied Packaging Research

Oxidation of polyunsaturated fatty acids (PUFA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in fish causes loss of product quality. Oxidative rancidity causes loss of nutritional value and undesirable color changes. Therefore, powerful antioxidant extracts may provide a relatively low cost and natural means to reduce oxidation, resulting in longer, higher quality and higher value shelf life of foods.

In this study, we measured synergistic effects of red cabbage antioxidant and vacuum packaging on lipid oxidation in fresh tilapia patties using thiobarbituric acid reactive substances (TBARS) assay, peroxide value (PV), pH and color analysis.

Concentrated red cabbage extract was obtained ...

Dna Barcoding Analysis Of Seafood Accuracy In Washington, D.C. Restaurants, David Stern, Eduardo Castro Nallar, Jason Rathod, Keith A. Crandall

Computational Biology Institute

In Washington D.C., recent legislation authorizes citizens to test if products are properly represented and, if they are not, to bring a lawsuit for the benefit of the general public. Recent studies revealing the widespread phenomenon of seafood substitution across the United States make it a fertile area for consumer protection testing. DNA barcoding provides an accurate and cost-effective way to perform these tests, especially when tissue alone is available making species identification based on morphology impossible. In this study, we sequenced the 5′ barcoding region of the Cytochrome Oxidase I gene for 12 samples of vertebrate and invertebrate ...
