Understanding aroma impacts of four important volatile sulfur compounds in Oregon Pinot noir wines

Creator:: Tsai, I-Min
Abstract:: Sensory properties of four important volatile sulfur compounds, dimethyl disulfide (DMDS), diethyl disulfide (DEDS), methanethiol (MeSH) and ethanethiol (EtSH), were determined in base Oregon Pinot noir wine in order to understand their impacts on wine aroma. Detection thresholds of these four compounds in base wine were determined first. All four...

Investigating the Quality Dynamics of American Aroma Hops Intended for Dry-Hopping Beer

Creator:: Lafontaine, Scott R.
Abstract:: Historically, brewers have used dry-hopping (a cold extraction of nonvolatile and volatile chemicals from hops into fermenting or finished beer) to increase the microbial stability and shelf life of their beer. As hoppy beer styles have gained in popularity over the last decade (2007-2017), the objective of dry-hopping has turned...

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...

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...

A study of antimutagenicity in yogurt

Creator:: Sudarshan, Nadathur R.
Abstract:: The purpose of this study was to identify antimutagens in yogurt active against the experimental colon carcinogen, N-methyl-N'-nitro-N-nitrosoguanidine (MNNG). Our initial experiments showed that acetone extracts of yogurt, or milk fermented by various lactic acid bacteria were antimutagenic against MNNG and 3,2'-dimethyl-4-aminobiphenyl (DMAB) in the Ames test (Salmonella typhimurium TA...

Evaluating a value-added product through studies on consumer acceptability, sensory properties, and their correlations to biochemical and instrumental texture properties : the case of Pacific whiting (Merluccius productus) individually quick frozen (IQF) fillets

Creator:: Aksornsri, Weeraporn
Abstract:: Pacific whiting (Merluccius productus) is the most abundant groundfish species off the California, Oregon and Washington Coasts. The fish are mainly used as a raw material for the production of surimi. However, it is not economically wise to depend only on one product. There is a need to diversify the...

Effects of cyclopropenoid fatty acids on liver plasma membranes of rainbow trout (Salmo gairdneri)

Creator:: Marino, Donald R. (Donald Robert)
Abstract:: Cyclopropenoid fatty acids (CPFA), which are a group of fatty acids produced by plants of the order Malvales, are known to induce adverse physiological effects when administered to a variety of animal species. A structurally strained cyclopropene ring is present in all CPFA and is believed responsible for the toxic...

A comparison of porous polymers used in collecting organic volatiles in foods

Creator:: Boyko, Alayne Linda
Abstract:: Porapak Q, Chromosorb 102, and Tenax GC, three porous polymers commonly used as adsorbents in headspace analyses were investigated. The retention times of various low-boiling compounds relative to water were measured on the collection columns to determine which compounds would be lost during the water removal step employed after sampling...
