The Examination of Escherichia coli Contamination via Agricultural Water Applications and Survival During Pre-Harvest Field Curing of Dry Bulb Onions

Creator:: Racine, Jason R.
Abstract:: 2020 and 2021 brought the first reported outbreaks of salmonellosis epidemiologically linked to dry bulb onions in the United States. Outbreak investigations were not able to implicate a specific source of the contamination but speculated that contaminated water was a significant contributor. The Produce Safety Rule established minimum standards for...

Frameshift mutagenicity of flavonol glycosides activated by human fecalase enzyme

Creator:: Dardiri, Moawia Mohamed
Abstract:: Many substances in the plant kingdom and in man's diet occur as glycosides. Recent studies have indicated that many glycosides that are not mutagenic in tests such as the Salmonella/microsome test become mutagenic upon hydrolysis of the glycosidic linkages. The Salmonella/microsome test utilizes a liver homogenate to approximate mammalian metabolism...

Assessing the impact of temperature on grape phenolic metabolism

Creator:: Cohen, Seth D.
Abstract:: Many climatic factors influence grape berry composition including nutrient status, water availability, biotic stress, sun exposure and temperature. Previous research examined the effects of many factors listed above and much progress has been made. It is often difficult, however, to separate effects that typically confound each other, such as sun...

Effect of organic production system and harvest date on the quality of blackberry fruit for fresh and processed markets

Creator:: Liu, Mingyang
Abstract:: Blackberry (Rubus sp.) fruit are a good source of phenolic compounds and anthocyanins, and are consumed in fresh and processed forms. Though organic products become more popular, limited information is available about how different organic production methods affect the post-harvest quality of blackberry fruit. The objective of this project was...

Efficacy of electrolyzed oxidizing (EO) water combined with UV-C light or gas exchange on sanitization of Jalapeno pepper using Serratia marcesens as surrogate for Salmonella

Creator:: Ekundayo, Olufunmilayo R.
Abstract:: Jalapeño peppers are usually consumed raw and fresh with minimal processing. They contain antioxidants and bioactive compounds which are of human health benefits. There have been an increasing number of reports of foodborne outbreaks attributed to inaccessibility of sanitizers to Salmonella , E.coli and Listeria monocytogenes when embedded in fruit...

Volatile composition of Pinot Noir grapes and wines under different viticultural practices in western Oregon

Creator:: Feng, Hui
Abstract:: High vegetative growth of Pinot Noir vine is a common problem in most vineyards of Oregon's Willamette Valley, where sunlight exposure and heat accumulation are limited. Consequently, growers in this region commonly use vineyard management strategies to regulate vine vigor and improve grape and wine quality. Wine quality is greatly...

Risk Assessment of Salmonella in Raw Hazelnuts and use of Propylene Oxide as a Potential Mitigation Strategy

Creator:: Wright, Daniel G.
Abstract:: Multiple outbreaks of foodborne illness (Salmonella and E. coli O157:H7) have been associated with tree nuts and tree nut products since the early 2000s. In response to these outbreaks and many others in fresh produce and peanut butter, Congress created and passed the Food Safety Modernization Act (FSMA) to require...

The effects of cyclopropenoid fatty acids on structural components of microsomal membranes

Creator:: Morrissey, Michael Thomas
Abstract:: Studies were conducted to determine the effects of cyclopropenoid fatty acids (CPFA) on the microsomal membrane of livers of rainbow trout (Salmo gairdneri). Slab and tube gel electrophoresis of microsomes from trout fed a CPFA diet (CPFA-microsomes) for varying time periods showed a decrease in the number of protein bands...

Differences in Taste Responses between Tongue Regions

Creator:: Colvin, Julie L.
Abstract:: Due to a combination of misinterpretation and misleading illustration, the premise of a “tongue map”, which indicated that sweetness could only be detected at the front of the tongue and bitterness could only be detected on the back, became wide spread. In fact, all taste qualities can be detected on...

Roles of yeast and lactic acid bacteria in malolactic fermentation of wines : a chemical and sensory study

Creator:: Avedovech, Richard M.
Abstract:: The purposeful induction of malolactic fermentation (MLF) in wines such as Pinot Noir and Chardonnay is an established commercial wine making practice in Oregon. This induction is not always successful, especially with white wines, such as Chardonnay. A study was initiated to examine the compatibility of yeasts commonly used in...
