Analysis of proanthocyanidin A2 and its presence in various commercial products

Creator:: Koerner, Jayma L.
Abstract:: Proanthocyanidins (PACs) containing A-type linkages, like those found in cranberry, have been implicated as beneficial phenolic compounds in human health, but much research is still required to better understand their activity fully. One major impediment to progress has been the existence of effective analytical methods for A-type PAC quantification. This...

Nutritional and Genetic Aspects of Sulfite Excretion During Fermentation by Wine Strains of Saccharomyces cerevisiae

Creator:: Alessandri, María P.
Abstract:: Reductive sulfate assimilation, the biological process by which sulfur-containing amino acids and key derivatives are synthesized from sulfate, is broadly shared among bacteria, fungi, and plants. It is the major, if not sole source of methionine and cysteine for Saccharomyces cerevisiae during wine fermentation. Two obligate intermediates formed in the...

Impact of Pre-fermentation Cold Soak Conditions on Pinot Noir Wine Quality

Creator:: Fu, Mengying
Abstract:: Wine volatile composition is one of the most important components of wine quality, and it is greatly affected by multiple factors, including grape variety, viticultural practices, and winemaking procedures. Pre-fermentation cold soak is one of the winemaking techniques widely undertaken by winemakers to modify their red wine quality. Imposing a...

Effect of Regulated Deficit Irrigation on Malbec and Syrah Grape and Wine Quality

Creator:: Yuan, Xiaoxi
Abstract:: The water status of grape vine throughout the growing season is a primary determinant of vine vigor and berry composition. The concentrations of volatile compounds and precursors in grape berries are highly influenced by viticultural practices. Imposing a water deficit on the vine during berry development is an important vineyard...

Shelf life and microbial content of fluid milk from nine processing plants in Oregon

Creator:: Wustenberg, Liam Robert
Abstract:: High-temperature-short-time pasteurized fluid milk commonly has a shelf life around 16-19 days. The aim of this study was to determine the shelf life of fluid milk in Oregon and characterize the bacterial growth over 23 days. Samples of pasteurized 2% milk were collected at six time points from all nine...

Inactivation of bacterial pathogens in drinking water

Creator:: Hartlerode, Evelyn R.
Abstract:: Wine is known to have been enjoyed since ancient times. Although early civilizations where unaware of scientific mechanisms of the properties of wine, empirical methods allowed them knowledge of its intoxicating effects as well as its healthful properties. These properties lead the ancients to use wine for many purposes including...

Effects of cover crop and vineyard floor management on young vine growth, soil moisture, and weeds in an establishing vineyard in the Willamette Valley of Oregon

Creator:: Fredrikson, Levi
Abstract:: Five vineyard floor management treatments were evaluated in a young vineyard in western Oregon to better understand the effects on vine growth and nutrition, soil moisture dynamics, and weed control during 2009 and 2010. Treatments included two mulched treatments where mowed alleyway residue was transferred in-row at rates of 1x...

Development of a method to measure protein in red wines : a survey of protein, mannan and tannin in Pinot noir wines

Creator:: Smith, Mark R.
Abstract:: A number of methods to isolate and quantify protein in Pinot noir wines were evaluated. The combination of precipitation by acetone containing 10% w/v trichloroacetic acid followed by quantification with the Bradford assay, reported in yeast invertase equivalents yielded the most accurate results when compared to micro-Kjeldahl analysis. The technique...

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...

Free Monoterpene Isomer Profiles in White Wine : Effect of Grape Variety, Region and Style and Impact on Odor Perception

Creator:: Song, Mei
Abstract:: Monoterpenes are important volatile compounds to the aroma of many white wines. Many monoterpenes are chiral and found in wine as different isomers. These isomers (also known as enantiomers) are non-superimposable mirror images of each other, maintain the same molecular structure and in many instances possess different sensory characteristics. Much...
