Embodiment 1

[0044] A preparation method for dried tuna, comprising the following steps:

[0045] 1) Thawing: Take the tuna out of the freezer. First thaw the tuna in still water at a temperature of 3°C for 2.5 hours, then thaw the tuna in running water at a temperature of 12°C for 1.5 hours, and finally thaw the tuna in salt water at a temperature of 22°C for 45 minutes. The concentration of table salt in the water is 4.5 g / mL. In each thawing process, the weight of the liquid used for thawing is 4.5 times that of the tuna, and the liquid is subjected to ultrasonic treatment during the thawing process of running water and saline solution, the ultrasonic frequency is 35KHz, and the ultrasonic power is 350W.

[0046] 2) Cleaning and slicing: remove the fins, head, tail, viscera and skin from the thawed tuna, remove the middle bone, and then wash and slice the fish body to obtain fish fillets.

[0047] 3) Pretreatment of fish fillets: Soak the fish fillets in the pretreatment solution for ...
