Determination Of Free Fatty Acid And Triglyceride Fatty Acid Of Food Fats Using A Rapid Gas Chromatographic Method, Aubreyona Migliori
Determination Of Free Fatty Acid And Triglyceride Fatty Acid Of Food Fats Using A Rapid Gas Chromatographic Method, Aubreyona Migliori
Fall Student Research Symposium 2021
Food fats are primarily triglycerides composed of esterified fatty acids on a glycerol backbone. To measure the fatty acid content of foods, a derivatization reaction is conducted which transfers the fatty acids from glycerol to methanol, forming a fatty acid methyl ester (FAME). FAMES are measured using gas chromatography with flame ionization detection (GC-FID). Free fatty acids in foods are a result of a degradation reactions and are considered a defect. This decreases consumer acceptance and expedites further deterioration which decreases the value of edible oils. The goal of this study was to develop a rapid and sensitive method to …
The Effects Of Various Carbon Sources And The Presence Of Vitamin B-12 On The Production Of 1,3-Propanediol By L. Reuteri., Kayden Stevenson
The Effects Of Various Carbon Sources And The Presence Of Vitamin B-12 On The Production Of 1,3-Propanediol By L. Reuteri., Kayden Stevenson
Fall Student Research Symposium 2021
Dairy product preservation has evolved over thousands of years and has been a major benefit to humanity by creating stable, nutrient-dense food sources. Today the lactic acid bacteria Lactobacillus reuteri is important in preserving fermented dairy products through the production of the compound reuterin. Reuterin (1,3-propanediol) demonstrates antibiotic properties that prevent the fermentation of dairy products by undesirable bacteria. The purpose of this study is to determine if L. reuteri can produce 1,3-propanediol from a variety of carbon sources. Bacterial strains were incubated in the presence of a carbon source with vitamin B-12 or without B-12 for seven days with …
Climate Change Impacts On Atmospheric Ammonia And Implications For Human Health, Casey Olson, Connor Snow, Bridger Jorgensen
Climate Change Impacts On Atmospheric Ammonia And Implications For Human Health, Casey Olson, Connor Snow, Bridger Jorgensen
Fall Student Research Symposium 2021
According to national data Cache Valley has the highest concentrations of atmospheric ammonia in the nation. This study aims to answer the questions of whether climate variables and events such as precipitation, averaged winds, geopotential height, and teleconnections can be used to predict the behavior of pollutants and how human biology is potentially affected. Data from the Utah Climate Center shows that the 3rd yearly quartile has the highest levels of airborne ammonia due to the high levels of fertilizer use and livestock emissions in the farming industry in Cache Valley. After data analysis, there seems to be a connection …
