In addition, CMC (carboxy methyl cellulose:) is used as a carbohydrate. For CMC, carboxymethylated cellulose containing more than 40% of hydroxyl groups is well soluble in cold water and becomes a stable colloidal solution with high viscosity. Such CMC is used as a thickener or emulsion stabilizer to increase the viscosity, absorbs moisture without being absorbed in the intestine and plays an important role in molding, but should be used in less than 2% of the total feed.

Potato starch is used for starch, and starch absorbs water during gelatinization to help molding and is used for the purpose of increasing the volume.

Calcium oxide uses eggshell calcium, and when it dissolves in water, it dissolves the protein on the meat surface, creating conditions for phosphate and protein to adhere well.

Transglutaminase plays an important role in the protein binding technology of real meat of the present invention. It is an enzyme that promotes cross-linking polymerization between protein molecules, and cross-linking between glutamine and lysine residues of protein molecules It is an enzyme that promotes binding and polymerization.
