Effect of sensory properties and health information on consumer acceptance and purchase of colorful fresh market potatoes

Creator:: Wechsler, Linda J.
Abstract:: Potato varieties characterized by non-conventional skin and flesh colors (purple, red, yellow) have the potential to revitalize consumer demand for fresh market potatoes because of their unique appearance and health benefits. Red and purple potatoes contain anthocyanins, which are flavonoids responsible for red, blue, and purple pigments in plants. Yellow...

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...

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...

Application of ozone as a disinfectant for commercially processed seafood

Creator:: Hansen, Jenny K.
Abstract:: Pacific oysters (Crassostrea gigas), Alaska pink salmon (Oncorynchus gorbuscha) roe and chum salmon (Oncorynchus keta) fillets were treated with aqueous ozone in both pilot plant and commercial settings to determine its effect on shelf-life and microbial changes. The microbial quality was analyzed by conducting pyschrotrophic and coliform plate counts on...

The use of high pressure process to shuck oysters, reduce microbial load and extend shelf-life

Creator:: He, Haian
Abstract:: Whole oysters were processed under a series of pressures from 30,000 to 45,000 psi at different holding times (0, 1, and 2 min) and then stored at <4°C, for 27 d. During the shelf-life study, the quality of oysters was determined by measuring pH, moisture content, and microbial counts including...

Isolation of a natural antioxidant from shrimp waste

Creator:: Li, Shiao Jing
Abstract:: Shrimp waste samples were extracted with a variety of organic solvents. Each fraction was measured for antioxidant activity by determining the rate of oxidation of β-carotene-linoleic acid in an emulsion system. An ethanol extract exhibited the highest antioxidant activity. Purification of the most active fraction was accomplished by thin layer...

Conversion of lignocellulosic biomass : analysis of substrate characteristics

Creator:: Meunier-Goddik, Lisbeth
Abstract:: The objective of this research was to investigate the influence of physicochemical properties of lignocellulosic biomass on the rate and extent of cellulose conversion, i.e. the "hydrolyzability" of the substrate. The initial two parts of this thesis investigated the interactions between various components of pretreated biomass. The relevance of cellulase...

Characteristics of Northern squawfish (Ptychocheilus oregonensis) and feasibility for utilization as human food

Creator:: Lin, Dongdong
Abstract:: The characteristics of Northern squawfish (Ptychocheilus oregonensis) and the feasibility of utilization of this species for human consumption were investigated. In the first experimental phase, the iced storage characteristics of squawfish were determined. Quality changes were monitored over 24 days of storage by chemical, physical, microbiological and sensorial methods of...

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...
