The non-protein nitrogen of fish muscle constitutes' a small fraction of the
total nitrogen content of the fish. However, the nitrogenous extractives
of fish muscle which consist of ammonia and trimethylammonium bases,
guanidine and imidazole derivatives, and miscellaneous substances such
as urea, amino acids, purines and pyrimidines are of signifkance from the
aspect of preservation and processing of fish. These substances probably
influence the potential keeping quality and appear to contribute to the flavour
of the fish. The nature and concentration of their decomposition products
are of primary importance in deciding the edibility of the fish. The changes
in the concentration of some of these constituents reflect the early changes
occurring in fish muscle prior to the onset of organo leptically detectable
spoilage and hence are of value as tests for the quality' of fish.
