Indicators of chemical constitution of fish, the extent of autolytic processes which
are accumulation of tissue fermentation enzymes, as well as fat, protein, water,
carbohydrates, mineral substances content reflect their organoleptic parameters of both
raw materials and finished product. Therefore, one of the tasks of our research was to
study the chemical composition of the raw material (Table 1).
