FIELD: food industry.
SUBSTANCE: invention relates to fish industry, particularly to fish preservation in cooling medium with ultrasound treatment, and can be used to prevent fish from spoiling and increase its shelf life. The method involves raw material preparation and treatment by ultrasound with the frequency of 110-880 kHz, intensity of 0.5-10.0 W/cm2 during 20-30 minutes. The ultrasound generator is placed at the distance of not more than 300 mm from the raw material surface. In the course of ultrasound treatment and the following storage the raw material is kept in ice-water-salt suspension with the ice content of 10-50%. The ice crystals are 0.1 mm at most and common salt concentration in the suspension amounts to 2.0-3.5%.
EFFECT: invention allows for the storage of chilled fish for up to 20 days.
