Abstract
ABSTRACTThe changes in concentration of adenosine triphosphate (ATP) and related compounds were examined as well as free amino acids, organic acids, betaines, glycogen and glycolytic metabolites in the Japanese baking scallop (Pecten albicans) during storage at 0° and 5°C. High amounts of free amino acids and glycine betaine were found. Adenosine monophosphate, inosine and hypoxanthine accumulated during storage, but inosine monophosphate was not detected. Hypoxanthine concentration was considered more appropriate as a freshness index than K value. Taurine, glycine and arginine were the main free amino acids and accounted for 91% of the total immediately after death. D‐lactate increased, but no substantial change of L‐lactate was detected during storage.
