Freshness was measured by estimating K-values of the samples at 0°, 10°, 20° and 30°C, whereas thermo-stabilities of actomyosin at 25°, 30° and 35°C by way of liberated inorganic phosphate. Rate constants of freshness lowering and inactivation of AM-Ca^<2+>-ATPase activities were evaluated. Regardless of the species, the freshness lowering rate increased with temperature as expected. Among the samples, Hanafuedai gave the highest lowering rate. The thermo-stabilities of the AM-Ca^<2+>-ATPase activities of the samples varied with the species. The actomyosin of Kyusenfuedai and Kidai appeared to be more stable than Hanafuedai and Hamadai at 30°C.}, pages = {65--72}, title = {Biochemical Studies on the Keeping Quality of Fish Muscle : Lowering of Freshness and Thermo-stability of Actomyosin ATPase Activity in the Dorsal Muscle of Various Fish from Ryuku Fishing Ground at Different Temperatures}, volume = {28}, year = {} }
