Substrate-gel electrophoresis for composition and molecular weight of proteinases or proteinaceous proteinase inhibitors.
A rapid, sensitive, and generally applicable substrate-sodium dodecyl sulfate-polyacrylamide gel electrophoresis method for detection of proteinases or proteinaceous protease inhibitors in biological… Expand
Control of chemical composition and food quality attributes of cultured fish
- N. Haard
Abstract The consumer's acceptance of fishery products depends on several attributes of food quality. Important attributes of food are safety, nutrition, flavor, texture, color, and the suitability… Expand

Enzymes. Enzymes and seafood quality. Control of enzyme activity in seafoods. Industrial application of enzymes.
Estimation of protein digestibility—I. Development of an in vitro method for estimating protein digestibility in salmonids (Salmo gairdneri)
Abstract A pH-stat in vitro assay method using enzyme fraction from fish pyloric ceca was developed for estimating protein digestibility in salmonid diets. The data obtained by pH-stat method were… Expand
Enzymes with Peptidase and Proteinase Activity from the Digestive Systems of a Freshwater and a Marine Decapod
Peptidase and proteinase activities from the digestive systems of langostilla (Pleuroncodes planipes) and crayfish (Pacifastacus astacus) were evaluated. Hepatopancreas extracts hydrolyzed specific… Expand
Trypsin from Greenland cod, Gadus ogac. Isolation and comparative properties.
Trypsin(ogen) was isolated from the pyloric ceca of Greenland cod. Greenland cod trypsin catalyzed hydrolysis of N alpha-benzoyl-DL-arginine p-nitroanilide, tosyl arginine methyl ester and protein… Expand
The use of proteolytic enzymes to extract carotenoproteins from shrimp wastes
CHARACTERIZATION OF PROTEINASE CLASSES IN LANGOSTILLA (PLEURONCODES PLANIPES) AND CRAYFISH (PACIFASTACUS ASTACUS) EXTRACTS
Proteinases (EC 3.4.21-24) in langostilla extract and crayfish hepatopancreas were classified using site specific effectors or chelators for either serine, cysteine, aspartic or metallo classes.… Expand
pH-stat method to predict protein digestibility in white shrimp (Penaeus vannamei)
Abstract In aquaculture, feeding trials are the most dependable method of measuring nutritive value of feeds. However, these methods are time consuming, expensive, and the results may be affected by… Expand
Chemical composition and protein digestibility of poultry by-product meals for salmonid diets
Abstract Poultry by-product meal (PBM) is a potential substitute for a portion of the fish meal typically used in salmonid feeds. The nutritional value of commercial PBM as a fish meal replacement… Expand
