In the studies reported in this papar, the author dealt with the enzymatic degradation of the aquatic animal muscles with the results summarized as follows.
In the aquatic animal muscles, the formation of ammonia in a considerable amount was perceived when pyloric coeca extracts or proteolytic enzyme were used, while it could hardly be observed when beef and whale meat were used as substrate.
Ammonia was found to be present in the water-extracted residue of muscle immersed in pyloric coeca extract, while it was not found in the extract itself.
Therefore it may be concluded that the ammonia is a decomposition product of muscle protein derived by the enzyme in pyloric coeca.
