Impact of lees content, nitrogen, and elemental sulfur on volatile sulfur compound formation in Vitis vinifera L. cv. 'Pinot noir' wine

Creator:: Kraft, Daniel N.
Abstract:: One of the most common problems in wine production is the formation of hydrogen sulfide (H₂S) and other volatile sulfur compounds (VSCs), which can mask positive aromas at low concentrations and result in unpleasant aromas such as rotten egg, cabbage, garlic, and rubber at higher concentrations. Despite the large body...

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...

Harvest maturity of Cascade and Willamette hops

Creator:: Sharp, Daniel C.
Abstract:: Hops (Humulus lupulus L.) are primarily used to provide specific characteristics to beer, such as bitterness, aroma, flavor, and microbial stability. The chemical composition of hops, relative to how they are used during the brewing process, dictates the expression of these characteristics. Of the raw ingredients that go into making...

Factors that Influence the Sensory Characteristics of Dry-hopped Beer

Creator:: Vollmer, Daniel M.
Abstract:: When hops are added to beer, varying degrees of hoppy aroma persist in the finished beer as a result of a number of factors. Dry-hopping is a technique whereby hops are added to beer post-fermentation to leverage the maximum aroma potential of the hop essential oils while minimizing bitterness contribution...

Factors that Influence the Aroma and Monoterpene Alcohol Profile of Hopped Beer

Creator:: Sharp, Daniel C.
Abstract:: Hop aroma in beer is related to the unique compositional chemistry of the hops used in the brewing process. While the range of these compositions is quite diverse and primarily dependent on hop cultivar¹, other studies have also shown that cultivation, seasonality, harvesting², processing³⁴, and storage practices⁵⁶ contribute to differences...

Influence of Biotic and Abiotic Factors on Yeast Communities during Cold Soak and the Consequences for Wine Aroma

Creator:: Johnson, Jared D.
Abstract:: Pre-fermentation cold soak is a winemaking technique used to alter the color, mouthfeel, and aroma of red wine. While it is still debated what impact cold soak has on these wine quality parameters, current thoughts are that resident yeast populations found in fresh grape must play a role in altering...

Exploration into the Influence of Malolactic Fermentation Parameters and Pre-fermentation Juice Treatment on Chardonnay Mouthfeel

Creator:: Sereni, Anthony
Abstract:: Mouthfeel is one of the most important quality parameters of Chardonnay wines. Malolactic fermentation (MLF) is an important process in wine production, and influential to wine mouthfeel, with the reduction in acidity being particularly important for cool climate wines that generally have higher acidity such as Chardonnay. MLF is typically...

Production of SO₂ Binding Compounds and SO₂ by Saccharomyces during Alcoholic Fermentation and the Impact on Malolactic Fermentation

Creator:: Wells, A. and Osborne, J. P.
Abstract:: The objective of this study was to investigate the production of SO₂ and SO₂ binding compounds by wine yeast and the impact of the production of these compounds on the MLF at various time points during alcoholic fermentation. Fermentations were observed for a number of commercial wine yeasts in a...

The effect of hopping technology on lager beer flavor and flavor stability and the impact of polyphenols on lager beer flavor and physical stability

Creator:: Aron, Patricia M.
Abstract:: Beer is one of the most extensively consumed beverages world-wide and it is almost always brewed with hops (Humulus lupulus, L.). Hops provide beer with bitterness, aroma, flavor and texture and also enhance specific beer properties such as foam stability, clarity (colloidal stability), color, flavor stability and microbial stability. Hops...

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...
