Abstract
Frozen whale meat on the market was examined histochemically and electron-microscopically in comparison with fresh beef. The results obtained were as follows :
1. Granular glycogen was found in the protoplasm of the beef, but not in that of the whale meat.
2. The karyotin part was somewhat vague, and cavities of mitochondria were found there.
3. Some collapse was observed in the filaments of the protein in the muscular fibers. It is considered to be an indication of the collapse of the physical structure of protein molecules that the meat is dyed well by means of the acrolein·Schiff reaction.
4. These changes observed were so slight that they were considered to be ineffective to reduce the food value of the meat. Therefore the frozen storage of whale meat might be regarded as the approvable measure.
