Green Tea Aids In Overall Health, Noelle Norman

Undergraduate Research Conference

Green tea is highly effective in aiding in overall health if consumed on a daily basis and can reduce incidence of cardiovascular disease, obesity, type 2 diabetes, and certain types of cancer. The primary compounds found in green tea are polyphenols which include catechins, epicatechin(EC), epigallocatechin(EGC), epicatechingallate(ECG), andepigallocatechingallate(EGCG). Five research studies were analyzed to verify the validity of the hypothesis that green consumption is beneficial in overall health. In these studies, green tea was found to aid in weight loss with those who consumed green tea regularly, as well as having effects on thermogenesis and fat oxidation to control wait …

Estimation Of The Number Of Days Required To Determine Usual Antioxidant Intakes And Assessment Of The Prevalence Of Nutrient Inadequacy Among College Students, Catherine G. Davis

Master's Theses

High intake of antioxidant rich foods has been shown to decrease risk factors of chronic disease.  Young adulthood may be crucial in establishing healthy lifestyles including adequate nutrient consumption.

The present study was designed 1) to estimate usual nutrient intakes, 2) to calculate the number of days required to estimate usual antioxidant intake, and 3) to assess intake adequacy from diet and diet + supplement sources by using the Estimated Average Requirement (EAR).  The USDA Flavonoid and Proanthocyanidin databases, food consumption data, and dietary supplement use data from 60 students aged 18-25 years at the University of Connecticut were utilized. …

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 , …

Exposure Assessment Of Listeria Monocytogenes In Vacuum Packed Cold-Smoked Salmon In The Republic Of Ireland, Sapna Dass

Doctoral

Contamination of cold-smoked salmon with Listeria monocytogenes, a bacterium causing listeriosis, presents a risk to consumer health. The overall aim of this thesis was to investigate the prevalence and source of L. monocytogenes in different stages of vacuum packed cold-smoked salmon production chain/retail market and to develop a risk assessment model to quantitatively assess the risk of human listeriosis upon consumption of vacuum packed cold-smoked salmon. The study necessitated the identification of novel isolation techniques for the isolation and quantification of L. monocytogenes in vacuum packed cold-smoked salmon. The techniques currently used in isolation of L. monocytogenes from ready-to-eat food …

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. Different extraction procedures (blending …

White Potatoes, Including French Fries, Contribute Shortfall Nutrients To Children's And Adolescents' Diets, Marjorie Freedman, Debra Keast

Faculty Publications

To test the hypothesis that white potatoes (WP), oven-baked fries (OBF), and french fries (FF) contribute important nutrients within energy needs to children's and adolescents' diets, secondary analysis of 24-hour dietary recall data from the National Health and Nutrition Examination Survey 2003-2006 was conducted. Potato content of survey foods was determined using US Department of Agriculture recipe databases (Standard Reference (SR)-Link files). Nutrient content of potatoes was determined by linking SR codes to US Department of Agriculture food composition data. Daily nutrient intakes from potatoes were determined by applying the composition database to respondent's recall data. Sample-weighted data were analyzed; …

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 …
