Development of volatile compounds in Pinot noir grapes and their contributions to wine aroma

Creator:: Fang, Yu
Abstract:: It is often perceived that late maturity of grape gives a more complex aroma profile to Pinot noir wine, however, there is little understanding of the basic flavor chemistry of grape maturity on wine aroma. The aroma contributing compounds in Pinot noir were first identified by aroma extract dilution analysis...

Efficacy of water, sodium hypochlorite, peroxyacetic acid, and acidified sodium chlorite for reducing microorganisms on in-shell hazelnuts

Creator:: Weller, Lisa D.
Abstract:: Hazelnuts are commonly consumed raw and are valued for their numerous health benefits and antioxidant properties. Increased foodborne illness outbreaks associated with Salmonella and Escherichia coli O157:H7 contamination of tree nuts and peanuts generate a need for improving agricultural sanitation procedures. Food-safe chemical sanitizers have shown promise for reducing pathogenic...

Effect of high pressure processing on the survival of Vibrio parahaemolyticus strains in pure culture and Pacific oysters

Creator:: Calik, Hakan
Abstract:: Different strains of Vibrio parahaemolyticus (Vp) in broth cultures and Vp-inoculated live Pacific oysters (Crassostrea gigas) were subjected to high pressure processing (HPP) at 241, 276, 310, and 345 MPa. Results showed Vp numbers were reduced by HPP in both pure culture and whole oysters. Vp inactivation was dependent on...

Interactions of Trichoderma reesei exo-acting cellulases with p-aminophenyl 1-thio-β-D-cellobioside

Creator:: Piyachomkwan, Kuakoon
Abstract:: Cellulolytic enzymes capable of efficiently degrading crystalline cellulose are a complex mixture of endo- (endoglucanases) and exo-acting (cellobiohydrolases) enzymes. One approach to separating these enzymes is affinity chromatography. A new ligand, p-aminophenyl l-thio-β-D-cellobioside (APTC), is introduced for this purpose. The property of APTC in affinity chromatography is demonstrated using Trichoderma...

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...

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...

Experimental investigation of carbon dioxide (CO₂) laser perforation as a potential skin pretreatment for sugar infusion process of frozen blueberries

Creator:: Fujimaru, Tomomi
Abstract:: The purpose of this research was to examine the feasibility of carbon dioxide (CO2) laser perforation and its potential utilization as a novel skin pretreatment for the sugar infusion process of IQF (individually quick frozen) blueberries. In the first study, IQF blueberries were treated with varying degrees of laser perforation...

Characterization of factors affecting pectinmethylesterase activity in cucumber fruit

Creator:: Turk, Farzaneh
Abstract:: Pectinmethylesterase (PME) activity in fresh cucumber fruit was determined. The effects of several cationic species, temperature, pH, and acetic acid on the activity of cucumber PME was investigated. The efficacy of blanching, infiltration with CaCl₂ or acetic acid, and fermentation with 0 and 40 mM CaCl₂ on inhibition of cucumber...

Measurement of dimethylamine and trimethylamine in Dungeness crab, Cancer magister

Creator:: Gulan, Michael Peter
Abstract:: A rapid gas liquid chromatographic method was adapted to processed Dungeness crab for the determination of basic and neutral volatiles. Methylamine, dimethylamine, and trimethylamine were measured in processed Dungeness crab for the first time. Generally, the range for trimethylamine was 42 ppm for frozen crab to 700 ppm for iced...
