Inactivation of Clostridium perfringens in Meat Products

Creator:: Alnoman, Maryam M.
Abstract:: Clostridium perfringens type A strains are one of the main causative agents of gastrointestinal (GI) diseases in human and can cause both food poisoning (FP) and non-food-borne (NFB) diseases. Several factors contribute to the pathogenesis of C. perfringens type A strains including the wide presence of C. perfringens spores with...

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...

Evaluation of DNA recovery methods for the detection of soy in foods using real-time PCR

Creator:: Koh, Chern Lin
Abstract:: Food allergies are an important health problem and affect up to 2% of the adult population and 8% of children worldwide. Under the Food Allergen Labeling and Consumer Protection Act (FALCPA) of 2004, foods that contain or derive from the "Big 8" allergens (milk, egg, finfish, crustacean shellfish, tree nuts,...

Impact of parameter variability on the food process engineering calculations required for safety, quality and shelf-life estimations

Creator:: Chotyakul, Nattaporn
Abstract:: Quantitative procedures were developed to determine the effect of variability in the model parameters required for the estimation of microbial shelflife and thermal processing time. Monte Carlo simulations combined with these predictive models were implemented in Microsoft Excel™. In the first study, predictive models were used for shelf-life predictions based...

Color of strawberry juice and concentrate as influenced by heating and storage temperatures

Creator:: Hassanein, Sitir M.
Abstract:: This investigation was conducted to study the effects of blanching and storage temperatures on the color of strawberry juice and concentrate. Strawberry juice and concentrate (42°βrix) were prepared from blanched crushed Tioga strawberries. Crushed strawberries were blanched, in a steam-jacketed kettle, at 70°, 80°, and 90°C for 1 min. Ascorbic...

Influence of Fermentation Temperature and Nutrient Addition Schedules on Sensory and Chemical Characteristics of Traditional Honey Wine

Creator:: Twilley, John M.
Abstract:: Honey wine, also known as mead, is one of the oldest alcoholic beverages known to man. Made primarily from honey, water, and yeast, this beverage has recently been experiencing a resurgence in popularity. It is imperative that commercial producers focus on consistently creating quality products to differentiate themselves from competitors...

Formation of N-nitrosodimethylamine and nonvolatile N-nitrosamines from barley malt alkaloids

Creator:: Mangino, Mario M.
Abstract:: Amines formed by biosynthesis in germinated barley have been suggested as precursors for N-nitrosodimethylamine (NDMA) in barley malt dried by direct-fired kilning. This hypothesis was verified by germinating raw barley and exposing the resulting malt roots and clean malt to nitrous acid. Quantitation of the NDMA formed indicated that malt...

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...

Sensory changes in high pressure processed vs. heat processed food systems over time

Creator:: Rodakowski, Andrea M.
Abstract:: This study was undertaken to determine the sensory differences in high pressure vs. heat processed food systems after storage at ambient and refrigerated temperatures as determined by a trained sensory panel. Spanish rice and spaghetti with meat sauce were prepared and treated with heat and with high pressure processing (HHP)....

Composition of flavonoid phenolic polymers isolated from red wine during maceration and significance of flavan-3-ols in foods pertaining to biological activity

Creator:: Aron, Patricia M.
Abstract:: Representing the most common flavonoid consumed in the American diet, the flavanols and their polymeric condensation products, the proanthocyanidins, are regarded as functional ingredients in various beverages, whole and processed foods, herbal remedies and supplements. Their presence in food affects food quality parameters including astringency, bitterness, sourness, sweetness, salivary viscosity,...
