Abstract

The invention discloses an aquatic product preservative. The aquatic product preservative is especially suitable for fish products. The aquatic product preservative is prepared by dissolving the following components in water: sodium hexametaphosphate, sodium tripolyphosphate and sodium pyrophosphate in a ratio of 10 to 2 to 1, and the total weight of the sodium hexametaphosphate, the sodium tripolyphosphate and the sodium pyrophosphate accounts for 50%-75% of the total weight of the aquatic product preservative, wherein 15-20% of sodium alginate, 5-10% of ascorbic acid and 2-10% of glycerol are included. After being used for coating aquatic products, the coating preservative can form a layer of film on the surface of the aquatic products to play the roles of reducing bacterial pollution, preventing microorganism growth and weakening air oxidation, and the preservation effect is obviously superior to a common low-temperature preservation method. The aquatic product preservative has simple use method, less equipment investment and small operation site, and can be suitable for industrial batch production.
