The effect of nitrogen, irrigation, and cultivation on Pinot noir juice and wine composition from the Willamette Valley, Oregon

Creator:: Wall, Katherine Elizabeth
Abstract:: This study investigated how manipulating vineyard nitrogen status, irrigation levels and cultivation practices would effect nutrient composition, and anthocyanin and phenolic accumulation in Pinot noir juice and wine from a commercial Willamette Valley Oregon vineyard. Pinot noir fruit was sourced from a vineyard trial in the Benton Lane Vineyard, located...

Ultrafiltration of pear juice : chemical and physical analysis

Creator:: Hodgson, Jeanne
Abstract:: Ultrafiltration of d'Anjou pear juice in the batch mode with a Romicon HFXS MXII pilot-scale ultrafilter produced a "sparkling clear", light-colored permeate which was sterile, essentially free of pectin, and lower in phenolics than the feed juice. Retention characteristics of PM-50, PM-30 and PM-10 hollow fiber membranes were tested at...

Investigation of Optimal Extraction Conditions and Microencapsulation Technique for Stabilizing Anthocyanins and Polyphenols from Fruit Materials

Creator:: Wang, Wenjie
Abstract:: The objectives of this research were to investigate the optimal conditions for anthocyanins extraction from different anthocyanin rich fruit and to develop microencapsulation formulation for improving stability of anthocyanin extracts. In the extraction optimization study, two extraction methods, "conventional solvent extraction (CE)" and "ultrasound-assisted extraction (UE)" for three different anthocyanin-rich...

Descriptive analysis of two consecutive vintages of Oregon Pinot noir wines as effected by irrigation, tillage and nitrogen supplementation in the vineyard

Creator:: Hjorth, Heather Byrne
Abstract:: Two vintages of Vitis vinifera cv. Pinot noir wine from a viticulture trial evaluating nitrogen fertilization, tilling and irrigation underwent descriptive analysis using a modified version of free-choice profiling. Wines were made from three field blocks of the twelve factorial combinations of Irrigation (Dry or Irrigated), Tillage (Tilled or not...

Antioxidant potential of yeast containing beer

Creator:: Morris, Edward E.
Abstract:: It has been suggested that cellular damage from oxygen radicals is one of the processes leading to cardio-vascular disease and cancer. Natural antioxidants prevent uncontrolled oxidative reactions by decreasing molecular oxygen levels, scavenging chain-initiating and chain-propagating free radicals, chelating metals, or decomposing peroxides. Beer is rich in antioxidants, derived both...

Effect of berry integrity on proanthocyanidin extraction during wine production

Creator:: Cerpa-Calderon, Fiorella Karen
Abstract:: Proanthocyanidins are a grape-derived phenolic class of compound that provide wine with bitterness and astringency. Because of this, proanthocyanidins are considered to be essential components of wine quality. Proanthocyanidins are localized in the seed, skin and stem tissue of the grape berry and the composition of proanthocyanidins will vary depending...

Evaluation of the effects of nutrient supplementation on low nitrogen Chardonnay

Creator:: Specht, Anna Louise
Abstract:: Low nitrogen Chardonnay juice from an Oregon winery was fermented with a series of nutrient supplements, including diammonium phosphate (DAP), Fermaid K, Superfood, yeast extract, yeast hulls and thiamine. These treatments were evaluated for their contribution to the yeast assimilable nitrogen content (YANC) of the juice, which consists of the...

Apple polyphenolics and their antioxidant properties : influence of cultivars, post-harvest storage, and 1-MCP treatment

Creator:: Widyasari, Maria Angela Artania
Abstract:: The distribution of total phenolics, antioxidant capacity, monomeric anthocyanin, and ascorbic acid contents in the peel and flesh of Red Delicious, Granny Smith, and Fuji apples during a six-month storage period were determined. In addition, the effect of 1-MCP (1-Methyl cyclopropene) on these parameters of the edible portion of apples...

Development of anthocyanins and proanthocyanidins in Pinot noir grapes and their extraction into wine

Creator:: Pastor del Rio, Jose L.
Abstract:: Color stability and mouth feel quality are two of the most important aspects of red wine quality. Anthocyanins and proanthocyanidins are responsible for these attributes and it has been shown that weather conditions during the growing season and grape maturity can effect these components in wine. However, investigations into proanthocyanidin...

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,...
