The autoxidation of 2, 4-decadienal

Creator:: Matthews, Roy Frank
Abstract:: 2, 4-Decadienal was autoxidized by subjecting a purified sample to an atmosphere of pure oxygen for 14 hours. A qualitative analysis of the autoxidative degradation products was made utilizing tandem gas chromatography and mass spectrometry. Additional information was obtained from the determination of the melting point of the DNP-hydrazone derivative...

Determination of dimethylamine in barley malt

Creator:: Yoo, Lee-joung
Abstract:: Dimethylamine (DMA), in addition to the alkaloids hordenine and gramine, has been suggested as a potential precursor of nitrosodimethylamine (NDMA) in malt. Analytical procedures were adopted and applied to extract and quantify DMA from malt, green malt, malt roots and raw barley. Ground malt was extracted at room temperature with...

Impact of malolactic fermentation on red wine color and color stability

Creator:: Burns, Tresider R.
Abstract:: Malolactic fermentation (MLF) is an important step in the production of wines and is commonly performed in red or cool climate wines to reduce acidity. In this study the impact of MLF on red wine color and the ability of Oenococcus oeni to degrade compounds important to the development of...

The cholesterol content of muscle and adipose tissue from country natural beef

Creator:: Huang, Xiaolin
Abstract:: The cholesterol content (mg/100 g wet tissue) of the longissimus dorsi muscle and the subcutaneous adipose tissue of "Country Natural Beef" and regularly produced beef was determined by a spectrophotometric method. Proximate analysis (moisture, fat and protein contents) of both types of beef was also determined. Country Natural Beef (natural...

Prevalence and Characterization of Listeria spp. Recovered from Pacific Northwest Produce Handling and Processing Facilities

Creator:: Jorgensen, John
Abstract:: Foodborne illness in the United States continues to be a complex and recurring issue despite our increased understanding of the pathogenic microorganisms responsible. Foodborne illness outbreaks and product recalls linked to pathogenic bacteria have been more frequent in the produce industry (e.g. fruits and vegetables) in the last ten years....

Development of High-Throughput Screening Methods to Determine Efficacy of “Clean-Label” Antifungals for Application on Cheese

Creator:: Jensen, Kristen
Abstract:: Cheese has been produced since ancient times and continues to be an important nutrient-dense staple in many diets around the world. Cheese quality is of high importance to consumers, and it is important for cheese producers to establish process controls to prevent and control cheese spoilage. Fungal spoilage is of...

Efficacy of Sanitizers at Controlling Listeria spp. and Listeria monocytogenes When Challenged with Variables Commonly Encountered in Food Processing Environments

Creator:: Boucher, Cara
Abstract:: Listeria monocytogenes (Lm) is a pathogenic bacterium associated with the foodborne disease listeriosis in humans. Listeriosis affects thousands of people in the U.S. yearly, with neonates, elderly, pregnant women, and immunocompromised persons disproportionately affected. Lm has a high mortality rate in these populations (20 - 30%) with symptoms including septicemia,...

The use of L-Aspartyl-L-phenylalanine methyl ester (Aspartame) as a sweetening agent in orange sherbet

Creator:: McPherson, Barbara Ann
Abstract:: The objective of this investigation was to develop an acceptable aspartame sweetened orange sherbet which might offer significant caloric reduction and cost advantages, and hence be applicable to commercial production. A control sherbet, with a preference level equal to a commercially available orange sherbet was used as the reference. An...

Composition of Pinot noir Wines Produced from Different Crop Levels

Creator:: Li, Jingwen
Abstract:: The production of high-quality wine is an important target for wineries worldwide, and low crop level (yield) has been one vineyard management criterion long believed to achieve wine quality. Low yields are most often achieved by removing clusters from the grapevine. Some studies show that cluster thinning can enhance grape...

Flavor development of cheddar cheese under different manufacturing practices

Creator:: Lemus, Freddy Mauricio
Abstract:: Cheddar Cheese samples (good cheese, weak cheese, cheese made with pasteurized milk, cheese made with heat-shocked milk, cheese from production plant A, cheese from production plant B, cheese made with adjunct culture, and cheese made without adjunct culture), were evaluated during the ripening stage. Proteolysis was studied by a fractionation...
