Evaluation of the off-flavor in English sole (Parophrys vetulus) using descriptive analysis techniques and consumer testing

Creator:: Geise, Laura Ann
Abstract:: English sole (Parophrys vetulus) is a flatfish found in abundance in the Pacific Ocean and is part of the Pacific Northwest's and California's commercial trawl fishery. Stock levels of this fish are at all time highs but there are decreased landings due to low demand and acceptability. With new regulations...

Extraction and production of n-3 polyunsaturated fatty acid concentrate from Pacific sardines (Sardinops sagax)

Creator:: Okada, Tomoko
Abstract:: Intrinsic characteristics of Pacific sardines were determined. The lipid content in sardines was initially low (6.79%) in the beginning ofthe season, increased to 22.95% in mid-August, and decreased slightly by the end of September. An inverse correlation (R² = -0.90) was found between lipid and moisture content. Analysis showed that...

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...

Intrinsic and extrinsic quality of West Coast albacore tuna (Thunnus alalunga)

Creator:: Wheeler, Sena C.
Abstract:: The purpose of this study is to identify the intrinsic and extrinsic quality characteristics of West Coast albacore tuna (Thunnus alalunga). Albacore tuna were troll caught off the Oregon coast and transferred to the Oregon State University Seafood laboratory in Astoria, Oregon. Core samples were extracted from six designated body...

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...

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...

Mercury levels in albacore tuna (Thunnus alalunga) and the effects of canning

Creator:: Rasmussen, Rosalee S.
Abstract:: Mercury is a toxic heavy metal released into the environment from both natural and anthropogenic sources. The organic form of mercury is a potent neurotoxin that is especially dangerous to developing nervous systems. Results of recent studies have caused the Food and Drug Administration (FDA) and the Environmental Protection Agency...

DNA-based identification of commercially important salmon and trout species (genera Oncorhynchus and Salmo) in North America

Creator:: Rasmussen, Rosalee S.
Abstract:: There are seven commercially important species of salmon and trout (genera Oncorhynchus and Salmo) in North America, many of which are closely related but command markedly different prices. The purpose of this research was to provide improved and novel methods for the detection of salmon species substitution on the commercial...

Development and characterization of shelf-life and sensory properties of restructured albacore tuna (Thunnus alalunga) rolls

Creator:: Roblero, Josef G.
Abstract:: Albacore tuna (Thunnus alalunga) rolls were developed using two albacore meat levels and three different treatment combinations. Albacore meat levels of 82 and 88% (Alb82 and Alb88) of the total weight formulation were examined. The different treatments consisted of 0.3% sodium tripolyphosphate (STPP), 0.3% STPP plus nitrites (150 ppm), and...
