Biochemical and Nutritional Evaluation of YellowClams

Abstract

Clams of different species such as Katelysia sp. Tapet sp., Paphia sp. and Meretrix sp. available in the Ashtamudi lake of Kerala were subjected to biochemical analysis and nutritional studies (two species). Clam muscle contained more amount of sarcoplasmic than myofibrillar protein. Glycogen, reserve increased relative to the age (size) of the animal but this was less in Paphia sp. Very slight variation in free amino nitrogen, pentose sugar or phosphorous content was observed among species. Meat from Katelysia or Tapes sp. was better in sensory qualities than that from Meretrix sp. Protein Efficiency Ratio of clam muscle was higher than the standard casein diet.
