A BIOLOGICAL FORMATION OF FORMALDEHYDE IN THE MUSCLE TISSUE OF GADOID FISH

Abstract

The muscle tissues of three gadoid fish including cod, Alaska pollock, and Japanese hake, tested after defrosting from frozen state, indicated the increase in the amount of formaldehyde with a parallel increase of dimethylamine during a storage at the temperature of 1 to 4C. And, a possibility of enzymatic formation of formaldehyde in gadoid fish was discussed. The writers are deeply indebted to Dr. T. ABE, ichthiologist of this laboratory, for his help by supplying the samples of Japanese hake with his taxonomical identification.
