Abstract
Abstract A cooling liquid for fresh fish is characterized by comprising the following components: water; one or more inorganic salts, preferably NaCl; one or more polyhydric alcohols, preferably glycerol, and ascorbic acid. By use of this cooling liquid fish may be cooled down to -1 to -2° C. without the fish flesh freezing. The cooling liquid permits considerable increase of the shelf life of fish.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
82 words
A method for preserving fresh fish without freezing, comprising: (a) treating the fish by contacting said fish with a cooling liquid comprising about 87 to 97 weight % water, about 0.5 to 1.5 weight % of at least one inorganic salt, about 2.0 to 9.5 weight % of at least one polyhydric alcohol, and about 0.5 to 2.0 weight % ascorbic acid; (b) cooling the treated fish to a temperature below 0° C.; and (c) storing the fish at the cooling temperature.
Claim 2
Independent Claim
82 words
A method for preserving fresh fish without freezing, comprising: (a) treating the fish by contacting said fish with a cooling liquid comprising about 87 to 97 weight % water, about 0.5 to 1.5 weight % of at least one inorganic salt, about 2.0 to 9.5 weight % of at least one polyhydric alcohol, and about 0.5 to 2.0 weight % ascorbic acid; (b) cooling the treated fish to a temperature below 0° C.; and (c) storing the fish at the cooling temperature.
