Abstract: An improved method for producing refrigerated flesh of fish, which comprises mixing ground fish flesh with (1) a powdery or granular solid colloid composed of 70 to 99% by weight of a crystallized and stabilized solid sugar alcohol such as sorbitol and 30 to 1% by weight of fine particles of an oil or fat such as colza oil dispersed in the sugar alcohol and (2) a powdery or granular polyphosphate, and refrigerating the mixture. The amounts of additives (1) and (2) are 1 to 10%, and 0.1 to 0.5%, respectively, based on the weight of the ground flesh. Pastes (such as "kamaboko") of seafood prepared from the refrigerated fish have better whiteness and elasticity than conventional products.
