Bacillus subtilis endospore coat protein solubilization methods for studying effects of high pressure precessing

Creator:: Gandhi, Kalpesh K.
Abstract:: Spores of foodborne pathogens such as Clostridium botulinum, Clostridium perfringens and Bacillus cereus are widely distributed in nature. Presence of those spores in food products, particularly C. botulinum spores in vacuum packed, ready-to-eat low-acid products, is a great safety concern. The research here described is a first effort towards understanding...

Aflatoxin B₁ metabolism by rainbow trout (Salmo gairdneri)

Creator:: Schoenhard, Grant Louis
Abstract:: Aflatoxins B₁, Q₁ and aflatoxicol, R [subscript o] F, but not B₂ were activated in the presence of NADPH by the 105,000 x g pellet from rainbow trout (Salmo gairdneri), Mt. Shasta strain, liver to products lethal to Bacillus subtilis GSY 1057 (metB4, hisAl, uvr-1). Electron microscopy confirmed the microsomal...

Survival Assessment, Inactivation Kinetics Models, and Farm-to-Table Quantitative Risk Analysis of Food Pathogens

Creator:: Deng, Kai
Abstract:: About 48 million cases of Foodborne illnesses (FBIs) are estimated to occur every year in the US. These are diseases caused by contamination of foods with bacteria, viruses, protozoa, parasites and toxic chemicals. Clostridium difficile infections (CDIs) are an important health-care and community associated problem. Since C. difficile spores have...

Plasma cholesterol levels, atherosclerosis and liver damage in rabbits fed cyclopropenoid fatty acids

Creator:: Ferguson, Thomas Lyle
Abstract:: In this five-week feeding study male New Zealand rabbits were fed diets containing cyclopropene fatty acids (CPFA), diets containing cholesterol, and diets with both CPFA and cholesterol added to test the effect of CPFA on cholesterol metabolism and atherosclerosis induction. When CPFA-fed animals were compared with control animals, they tended...

Edible food coatings to control potassium sorbate diffusion from surface into food bulk : characterization of the diffusion process in polysaccharide based films

Creator:: Vojdani, Fakhrieh
Abstract:: Edible coatings controlling preservative migration from surface to food bulk could inhibit surface microbial growth which is often the main cause of spoilage for many food products. In this project we focused our attention upon methylcellulose, hydroxypropyl methylcellulose, and chitosan as the structural component for such edible films. These films...

Cephalic phase insulin release : the role of oral glucose detection and its measurement in humans

Creator:: Pullicin, Alexa J.
Abstract:: Sensory stimulation from food-related cues elicits a number of rapid physiologic responses that prepare the gastrointestinal tract for efficient nutrient utilization and help minimize perturbations to metabolic homeostasis. Cephalic phase insulin release (CPIR) is one such response that specifically promotes glucose homeostasis by limiting the rise in blood sugar after...

Individual Differences in Retronasal Odor Responsiveness : Effects of Aging and Concurrent Taste

Creator:: Flaherty, Tyler J.
Abstract:: Taste sensitivity has been considered the primary chemosensory factor in studies of chemical senses and ingestive behavior. However, recent research has shown that retronasal olfaction is at least equally important in food preference and selection. Additionally, taste has been shown to modulate perceived intensity of retronasally perceived odors. The objectives...

An evaluation into the optimization and application of supercritical fluid extraction and the processing impact on the components in filtrated buttermilk powder

Creator:: Spence, Amy J.
Abstract:: The milk fat globule membrane, a major component in buttermilk, contains many complex lipids known to be involved in a variety of biological processes. Phospholipids, including sphingolipids, exhibit antioxidative, anticarcinogenic, and antiatherogenic properties and have essential roles in numerous cell functions. Filtration coupled with supercritical fluid extraction (SFE) may provide...

Aroma qualities of raw hops and hops in beer by trained panel free-choice profiling

Creator:: Stucky, Gregory J.
Abstract:: Hops contribute many desirable aromas to beer. Traditionally hop aromas have been described by the point of addition in the brewing process (dry-hop, finish-hop, or kettle-hop). The compounds present in the oil provide a wide range of aroma qualities. Since the composition of the oil is different for each hop...

An evaluation of blackberry harvest sanitation and the ability of foodborne pathogens to survive in blackberry products

Creator:: Sales, Melissa M.
Abstract:: Blackberries, genus Rubus, are an important Oregon agricultural commodity. In their fresh and processed forms, they offer many health benefits and may be able to help Americans better achieve fruit consumption recommendations because of convenience and pleasant sensory qualities. However, the susceptibility of blackberry products to contamination with bacterial pathogens...
