PURPOSE: To prepare a paste product of fish meat having high elasticity, preventing the evaporation of water during the long-term preservation of frozen ground fish and the denaturation in freezing, not causing flagging, by adding a polyhydric alcohol and xanthan gum to the meat.

CONSTITUTION: In preparing a paste product of sea food conventionally or preserving ground fish for a long time, ≤10wt%, preferably 2W6wt% based on treated fish or ground fish of a polyhydric alcohol such as glycerol, D-sorbitol, maltitol and ≤2wt% xanthan gum are added uniformly to it.
