The effect of wine matrix on the analysis of volatile sulfur compounds by solid-phase microextraction-GC-PFPD

Creator:: Davis, Peter M.
Abstract:: Constituents of the wine matrix, including ethanol, affect adsorption of sulfur volatiles on solid-phase microextraction (SPME) fibers, which can impact sensitivity and accuracy of volatile sulfur analysis in wine. Several common wine sulfur volatiles, including hydrogen sulfide (H2S), methanethiol (MeSH), dimethyl sulfide (DMS), dimethyl disulfide (DMDS), dimethyl trisulfide (DMTS), diethyl...

Volatile composition of Pinot Noir grapes and wines under different viticultural practices in western Oregon

Creator:: Feng, Hui
Abstract:: High vegetative growth of Pinot Noir vine is a common problem in most vineyards of Oregon's Willamette Valley, where sunlight exposure and heat accumulation are limited. Consequently, growers in this region commonly use vineyard management strategies to regulate vine vigor and improve grape and wine quality. Wine quality is greatly...

Grape and Wine Aroma Influenced by Vine Nutrient Status, Vigor and Crop Levels in Oregon Pinot Noir

Creator:: Yuan, Fang
Abstract:: Wine volatile composition is one of the most important constitutes of wine quality, and it is greatly influenced by number of factors. The studies herein were conducted to evaluate the grape and wine aroma affected by different vine nutrient status, vigor and crop levels of Oregon Pinot noir. In the...

Composition of Pinot noir Wines Produced from Different Crop Levels

Creator:: Li, Jingwen
Abstract:: The production of high-quality wine is an important target for wineries worldwide, and low crop level (yield) has been one vineyard management criterion long believed to achieve wine quality. Low yields are most often achieved by removing clusters from the grapevine. Some studies show that cluster thinning can enhance grape...

Flavor composition of transgenic raspberry bushy dwarf virus-resistant 'Meeker' raspberries

Creator:: Malowicki, Sarah Marie-Mahler
Abstract:: Raspberries have been popular since the time of the ancient Greeks. Red raspberries are cultivated throughout the world, particularly in the Pacific Northwest region of the United States and Canada. The raspberry bushy dwarf virus (RBDV) causes significant reduction in yield and crumbly fruit in raspberries, blackberries and raspberry-blackberry hybrids....

Flavor comparison of ultra high temperature processed milk heated by Ohmic heating and conventional methods

Creator:: He, Juan
Abstract:: Ultra high temperature (UHT) processing can extend shelf life of milk to several months without refrigeration, which is more convenient and energy saving than pasteurized milk. However, the poor acceptance caused by "cooked" flavors limits its marketing growth, especially in United States. Ohmic heating, which has a more uniform and...

Fruit quality evaluation of strawberries (Fragaria ananassa) grown in California and Oregon

Creator:: Jetti, Rajesh R.
Abstract:: Five genotypes from California (Ventana, Caniarosa, San Miguel, 13G97, and Venice) and Oregon (Totem, Puget Reliance, Puget Summer, Hood and Independence) were evaluated for quality. The volatile compounds were analyzed using head space solid phase micro extraction-gas chromatography-flame ionization detection (GGFID) and gas chromatography-mass spectrometry (GC-MS). Odor activity values of...

The Extraction and Analytical Profiling of Bioactive Phospho- and Sphingolipids from Commercial Whey Protein Phospholipid Concentrate

Creator:: Ferraris, Quintin M.
Abstract:: Milk is the first source of nutrition for all mammalian neonates. The complex matrix that constitutes milk has evolved to provide optimal nutrition for the newborn, for each species, respectively. Milk fat, originating in mammary epithelial, forms lipid droplets which are stabilized in the aqueous environment by bioactive polar lipids...

Development of volatile composition and C₁₃-norisoprenoid precursors in Pinot noir grape, Development of volatile composition and C13-norisoprenoid precursors in Pinot noir grape

Creator:: Yuan, Fang
Abstract:: This study first investigated the developmental changes in the volatile composition and carotenoids of Pinot noir grapes. Grape berries were sampled every week from pea size to harvest during the 2011 and 2012 season. Carotenoids and organic acids were analyzed by HPLC. Volatile compounds were extracted from crushed berries using...
