Abstract

Organoleptic, chemical and bacteriological changes occurring in Mrigal (Cirrhina mrigala), a major carp, were studied and the results discussed in comparison to reported figures for marine fish. The samples remained organoleptically acceptable for 5 weeks. Chemical indices of spoilage e.g. TVB, proteolysis and volatile acids appeared at a rather low rate during this period. There was no change in the pH. -Amino nitrogen decreased initially and then increased, while peptide amino nitrogen increased steadily. Changes were nearly the same in whole and filleted fish. Individual and species variations in non-protein nitrogen compounds were too large to serve as spoilage indices. Bacterial growth too was rather slow as compared to marine fish stored under identical conditions.
