Abstract
A method for improving frozen fish fillets treated by way of a salt-water immersion process includes the following steps: pretreating raw fish to obtain fish fillets; precooling the fish fillets; stacking the precooled fish fillets to obtain a fish fillet stack; freezing the fish fillet stack by using a salt-water immersion process, and performing power-variable ultrasonic wave treatment; and feeding the fish fillets into a cold storage, and performing freezing storage at minus 18 degrees centigrade. The power-variable ultrasonic wave treatment includes: firstly treating for 5 to 10 min under the power of 800 to 600 W, and then changing the power to 200 to 600 W for treating for 5 to 15 min. The freezing time of fish flesh is shortened, and formed ice crystals are fine and uniform, thereby preventing the damage of the formed ice crystals to cell walls.
