Assessment And Reduction Of Bacterial Contamination Of Fresh Farm Produce, Grace Cooper Oct 2017

Assessment And Reduction Of Bacterial Contamination Of Fresh Farm Produce, Grace Cooper

Honors Theses

Fruits and vegetables provide vital nutrients, vitamins, and enzymes that are essential for everyday function and a healthy lifestyle (Lassale, et al., 2016; “Getting vitamins from food (not pills)”, 2011; Rodriguez-Casado, 2016). Long-term benefits of consuming fresh farm produce include protection from many chronic medical conditions and illnesses, such as diabetes, cardiovascular diseases, and cancer due to their antioxidant effects (Oyebode, et al., 2014; Rodriguez-Casado, 2016). Additionally, fruit and vegetable consumption has been shown to benefit psychological health by improving overall happiness and well-being and decreasing depression and anxiety (Conner, et al., 2017). However, these physical and psychological benefits do ...


Synthesis, Isolation, And Characterization Of Potentially Carcinogenic Arginine-Based Heterocyclic Amines, Zachary Reichert Mar 2016

Synthesis, Isolation, And Characterization Of Potentially Carcinogenic Arginine-Based Heterocyclic Amines, Zachary Reichert

Honors Theses

Previous research demonstrates that meat cooked at high temperatures produces heterocyclic amines (HCAs)—a class of carcinogenic molecules—from burned creatin(in)e and amino acids. However, research performed in our lab, as well as in the peer-reviewed literature, suggests that substituting arginine for creatin(in)e may lead to HCA formation. Arginine is structurally similar to creatin(in)e and can be found abundantly in soy-based food products. Therefore, we have burned arginine and phenylalanine to investigate the potential formation of arginine-based HCAs. The present study attempts to isolate and characterize these potential arginine-HCAs.


Simultaneous Determination Of Bpa And Bps Using Uv/Vis Spectrophotometry And Hplc, Jean Eudes Benecyo Jan 2016

Simultaneous Determination Of Bpa And Bps Using Uv/Vis Spectrophotometry And Hplc, Jean Eudes Benecyo

Honors Theses

Bisphenol A (BPA) has been one of the most used plasticizers with more than 4.8 million tons produced in 2012. BPA is also an endocrine disruptor that has been linked to adverse health effects such as cancer, obesity, behavioral and mood changes, lowered fertility, developmental changes and more in humans and other animals. The evidence of the toxicity of BPA, even at very low levels, has caused many countries to limit its use, especially in baby bottles and other baby-related hard plastic items. In these times, BPA has been replaced with other bisphenols, such as Bisphenol S (BPS). BPS ...


Automated Aquaponics Design Report, Carson Miller Jun 2015

Automated Aquaponics Design Report, Carson Miller

Honors Theses

Aquaponic systems offer a solution to environmentally conscious, fiscally responsible individuals who wish to produce food products without the use of pesticides, genetic modification, or non-renewable resources. Further, the proliferation of inexpensive microprocessors and high quality sensors offers an opportunity for dynamic monitoring and error correcting within the aquaponic system. These aquaponic and electronic systems will be combined in this project to create an electronically monitored aquaponic ecosystem.


Bringing Bpa To Light: Determination Of Bisphenol A In Thermal Receipt Paper Water Samples And Lake Water Samples Using Fluorescence Spectrophotometry, Bailey Chitwood Jan 2015

Bringing Bpa To Light: Determination Of Bisphenol A In Thermal Receipt Paper Water Samples And Lake Water Samples Using Fluorescence Spectrophotometry, Bailey Chitwood

Honors Theses

Bisphenol A (BPA) is a chemical that is commonly used in harder plastic products, in the lining of food cans, and in thermal receipt paper. The usage of BPA in common products has become a concern for humans, especially for infants and young children, because of its effects as an endocrine disrupter. BPA has been linked to diabetes, cardiovascular disease, obesity, and certain developmental disorders. Because of the possible effects of BPA on the development of infants and young children, the use of BPA in baby bottles and other baby products has been outlawed. However, BPA is still used in ...


Economic And Political Implications Of Agricultural Subsidies And Us Farm Policy, Justin Bogardus Jun 2014

Economic And Political Implications Of Agricultural Subsidies And Us Farm Policy, Justin Bogardus

Honors Theses

This thesis pertains to agricultural subsidies, their economic and political implications and what would happen to both price and production levels of different crops should those subsidies be removed. The 3 main crops examined are corn, wool and soybeans. Technological advancements made after 1900 had a profound effect on productivity and efficiency, leading to a number of important economic effects. Market integration, economies of scale, market structure, vertical integration and subsidization, all led to government intervention in the form of regulation and subsidy. Farm policy, starting in early 1900s, focused on price stabilization policies and food programs through the different ...


The Role Of Underutilized Fish In New England's Seafood System, Taylor Witkin Jan 2014

The Role Of Underutilized Fish In New England's Seafood System, Taylor Witkin

Honors Theses

The global fisheries crisis has led to an increasing recognition for the need to relieve pressure on overfished, popular food fish stocks. Opportunities exist to shift consumer demand toward more sustainable choices, including fish that may be locally abundant. Attempts have been made to market underused fish (sometimes termed “trash fish”) that represent more sustainable alternatives; however, it is unclear whether consumers will choose to purchase these more sustainable options, particularly if underused fish are also unfamiliar. Chapter 1 reviews existing research and current issues surrounding sustainable seafood and the recent shift toward local, abundant, undervalued species in New England ...


The Effects Of Eating Behaviors And Exercise Patterns On The Processing Of Food And Exercise Related Stimuli, Carrie Potter Jan 2009

The Effects Of Eating Behaviors And Exercise Patterns On The Processing Of Food And Exercise Related Stimuli, Carrie Potter

Honors Theses

The effectiveness of Cognitive Behavioral Therapy (CBT) for eating disorders has established a link between cognitive processes and unhealthy eating behaviors. However, the relationship between individual differences in unhealthy eating behaviors that are not related to clinical eating disorders, such as overeating and restrained eating, and the processing of food related verbal stimuli remains undetermined. Furthermore, the cognitive processes that promote unhealthy and healthy exercise patterns remain virtually unexplored by previous research. The present study compared individual differences in attitudes and behaviors around eating and exercise to responses to food and exercise-related words using a Lexical Decision Task (LDT). Participants ...


Early Stage Detection Of Marine Oil Oxidation, Loren Lapointe May 2007

Early Stage Detection Of Marine Oil Oxidation, Loren Lapointe

Honors Theses

A method involving overnight stir bar sorptive extraction (SBSE) headspace gas chromatography/mass spectrometry (GC/MS) in negative ion chemical ionization (NICI) mode was developed to determine the presence of aldehydes (cis-4-heptenal, trans,trans-2,4-heptadienal, trans-2-octenal, cis-6-nonenal, trans-2-cis-6-nonadienal, trans-2-nonenal, and trans,trans-2,4-decadienal) in fresh and aged commercial fish oil (untreated and treated with antioxidant blends). Aldehyde standards were quantifiable to >100ppb levels using this method. Only trans,trans-2,4-heptadienal was shown to be present in the commercial fish oil and its presence was used to compare the performance of the two different antioxidant treatments in the fish oil. Includes ...


Cooking, Carol Miller Jan 1973

Cooking, Carol Miller

Honors Theses

From my project this semester, I have gained an insight into cooking that I have never known before. I will be able to use what I have learned in my everyday life from now on. The different ways of preparing foods is what is emphasized in this project report but this isn't all that I have learned. I was also able to gather recipes which I have kept on file. I have enclosed only a few examples. With the help of my advisor, Mrs. Hobgood, this study has encouraged me to further my interests in this field.

A New Me: A Study In Diet Therapy, Marsha Ellis

Honors Theses

Obesity is a major problem in our nation today. It Seems that we are eating too much and exercising too little. We can analyze, discuss, and write about obesity from now through eternity. However all of this is in vain, unless it causes us to lose weight.


An Ecological Study Of Coliform Bacteria Associated With Vaccinium Corymbosum, Harry C. Bittenbender Jan 1971

An Ecological Study Of Coliform Bacteria Associated With Vaccinium Corymbosum, Harry C. Bittenbender

Honors Theses

Recent research has shown that there are coliform populations associated with the cultivated high bush blueberry, Vaccinium corynbosum. This study is aimed at determining the ecology of these colofirms, as they are related to blueberry production from the farm to the warehouse. Tests will be made to identify the Salmonella group, those associated with "food poisoning." Total bacterial coliform counts will also be made. This paper is primarily an ecological study of the coliforms found on blueberry farms near Grand Junction, though fruit samples were taken from all warehouses of the M.B.G.A.
