Abstract A method for preservation of fish consists in that the original product is salt-cured and held, whereupon the fish is given a protective coating of a polymer composition containing polyvinyl alcohol, a mixture of poly-hydroxyethyleneglycol ethers of monoethanolamides of synthetic fatty acids of the C 10 -C 16 fraction, sorbic acid, glycerol and water, the mass percentage content of the components of said polymer composition being as follows: ______________________________________ polyvinyl alcohol 0.1 to 25.0
mixture of polyhydroxyethyleneglycol
0.00024 to 0.06
ethers of monoethanolamides of synthetic
fatty acids of the C 10 -C 16 fraction
sorbic acid 0.01 to 4.0
glycerol 10 to 15
water to make up 100,
______________________________________ whereupon the thus-obtained coated fish is treated with an aqueous modifying solution of the following mass percentage composition:______________________________________modifier 1 to 25water to make up 100.______________________________________
