[0033] A preparation method for cold tilapia fish skin, which comprises the following steps carried out in sequence:
[0034] S1 removes the flesh of the whole tilapia to obtain the fish skin with phosphorus;
[0035] S2 Soak the fish skin with phosphorus in an aqueous alkali solution with a concentration of 0.8-2.0 g / L for 30-60 minutes;
[0036] S3 blanching the soaked fish skin with phosphorus in hot water at 80-95°C for 6-20 seconds and then removing phosphorus;
[0037] S4 cooling the dephosphorized fish skin with ice water at 0-5°C to obtain ready-to-eat fish skin;
[0038] S5 adding seasoning to the obtained ready-to-eat fish skin to obtain cold tilapia fish skin.
[0039] In this embodiment, the whole fish is de-fleshed to obtain a complete fish skin with phosphorus, and then sterilized by soaking in an alkaline aqueous solution, and then further sterilized and blanched in hot water at 80-95°C to remove phosphorus, so that The obtained fish skin tissue is more compl...
