A new method was developed to estimate the minimum dietary requirement of phosphorus (P) for large fish for which conventional methods are not suitable. The method is based upon nonfecal (mainly urinary) excretion of inorganic P and total nitrogen from fish placed in a metabolic tank. In the first experiment, small and large rainbow trout (body wt 203 and(More)
High hydrostatic pressure has been demonstrated to be a useful technique for treating food to reduce the number of pathogenic organisms and to extend shelf life. Most research in this area has focused on bacteria. However, a concern in the sashimi (raw fish) industry is that nematode worms such as Anisakis simplex occur naturally in cold-water marine fish.(More)
Substitution of high oleic acid sunflower oil for herring oil in formulated salmonid diets affected the fatty acid composition of muscle, liver and visceral fat from coho salmon (Oncorhynchus kisutch) and rainbow trout (O. mykiss). Fish were fed diets containing either high oleic acid sunflower oil or herring oil as the supplemental lipid source (12.4 g/100(More)
The purpose of this study was to define the relationship between survival and temperature of nematodes of the species Anisakis simplex in microwave-processed arrowtooth flounder (Atheresthes stomias). Ten fillets (each 126 to 467 g, 0.5 to 1.75 cm thick), with an average of five larvae of Anisakis simplex per fillet, were processed to target temperatures on(More)
Immunochemical assays are powerful bioanalytical techniques with application to several areas in food science, including food analysis, microbiology, nutrition, food safety, food quality, and process control. In principle, immunochemical techniques can be applied to the analysis of any compound, with only one specific antibody needed that can be obtained(More)
Sterile ice cream and frozen yogurt were offered to immunosuppressed patients recovering from bone marrow transplantation. To obtain sterile products, two of the dairy desserts (prepackaged ice cream and frozen yogurt bars) were exposed to 40 kGy of cobalt 60 irradiation. Four different flavors of ice cream were aseptically prepared under a laminar airflow(More)
Survival of naturally occurring larvae of Anisakis simplex in fresh arrowtooth flounder (Atheresthes stomia) was determined after storage for specified periods at four freezing temperatures. All larvae were killed by 96, 60, 12, and 9 h at temperatures of -15, -20, -30, and -40 degrees C, respectively. The average percentages of live larvae per fillet at(More)
Let G = (V,E) be a 2-connected plane graph on n vertices with outer face C such that every 2-vertex cut of G contains at least one vertex of C. Let PG(q) denote the chromatic polynomial of G. We show that (−1)nPG(q) > 0 for all 1 < q ≤ 1.2040.... This result is a corollary of a more general result that (−1)ZG(q,w) > 0 for all 1 < q ≤ 1.2040..., where(More)
