After the fish is processed, 5 to 10 mm thick pieces of meat are to be taken, and the meat pieces are washed, dehydrated, seasoned, etc. to remove the animal's gum, trimethylamine, blood and other perishable components; then seasonings are added to stir and season the fish slices. The surface and the meat pellets are pasted and then frozen in the box. The fish meat is then cut into the desired size and shape in a frozen state and further processed into a food product. This method has a short treatment time and can maintain the freshness of the fish. The processed fish can be seasoned evenly. The method can be used together with cheese, butter, fish eggs, eggs, and seaweed to produce nutritious foods with various flavors. Example (from narrow-boared fish) First remove the head, viscera, and ovaries from narrow-tailed fish and wash them with water.

Rinse with water for 3 hours or soak in water and change the water every 30 minutes. In this way, animal glue, trimethylamine, blood and other substances in fish can be removed. After washing the treated fish, use a centrifuge to dehydrate the fish to a moisture content of 80% or less, add sugar 7 kg per 100 kg, sorbitol 14 kg, sodium glutamate 1 kg, and an appropriate amount of polymeric phosphate. Stir the seasoning so that the water in the fish flesh out. The whole material is in a paste state, and after 2 to 3 hours of frequent stirring, the seasoning liquid is soaked, poured into the desired shape of the box (be careful not to leave gaps between the meat pieces), and put it in the freezer below -20°C. freeze.
