Elastic polypeptide capable of improving fish intestine elasticity, fish intestines and preparation method thereof

Abstract

The invention discloses elastic polypeptide capable of improving fish intestine elasticity, fish intestines and a preparation method thereof. An amino acid sequence of the elastic polypeptide is VGVAPGAVALGILLGCASLAT, and the elastic polypeptide can remarkably improve elasticity of the fish intestines. The fish intestines comprise meat stuffing and casings, the meat stuffing comprises, by weight,65-70 parts of fish cream, 3-5 parts of chicken meat, 3-5 parts of lean fat, 3-5 parts of shrimp meat, 0.5-1 part of soybean isolate protein and 10-15 parts of elastic polypeptide, and the casings comprise 50-60 parts of algae vulcanized polysaccharide, 30-35 parts of tylorrhynchus extract, 10-25 parts of fish skin collagen and 30-35 parts of elastic polypeptide. The fish intestines prepared by the method are high in fish meat proportion and elasticity, nutritional and healthy. The casings are prepared by combining the tylorrhynchus extract and the elastic polypeptide with the collagen, thereby being high in elasticity, nutritional and healthy, so that the fish intestines are of higher popularization significance, and the preparation method is simple.

Description

technical field

[0001] The invention relates to the field of polypeptides, in particular to an elastic polypeptide for improving the elasticity of fish intestines, fish intestines and a preparation method thereof. Background technique

[0002] Fish sausage, the raw material mainly contains fish meat, because the meat of fish meat is too loose and tender, the meat filling is easy to loosen and the elasticity is not enough; or too much livestock meat is added to increase its elasticity, so the temporary ratio of fish meat becomes smaller , the taste is also covered by livestock meat, and the fish intestines made are essentially meat sausages. Therefore, how to improve the elasticity of fish intestines with fish meat as the main raw material is of great significance.

[0003] In addition, the production of fish casings is generally made of animal large intestines. The large intestine is a digestive organ of animals, and it is easy to accumulate many harmful substances, such as ...
