Abstract

The invention discloses a fresh shrimp freezing and antistaling agent as well as a fresh shrimp freezing and antistaling method. The antistaling agent is a mixture containing tea polyphenol, chitosan, antibacterial peptide, nisin, glucose oxidase, sodium chloride, lactic acid and trehalose. The antistaling agent is used for freezing and fresh-keeping of fresh shrimps; the fresh shrimp freezing and antistaling agent has natural components, and can be used for better protecting freshness of aquatic products, maintaining original appearance and state, reducing loss of proteins and other nutrients, inhibiting generation of bacteria, and substantially prolonging shelf-life and storage life.

Description

technical field [0001] The invention relates to the technical field of processing aquatic products, in particular to a fresh shrimp freezing preservation agent and a fresh shrimp freezing preservation method. technical background [0002] Our country is rich in seafood resources, both river prawns and sea prawns have large yields, shrimps are rich in nutrients, and the protein content is several to dozens of times that of fish, eggs, and milk; it is also rich in potassium, iodine, magnesium, and phosphorus. And other minerals and vitamin A, aminophylline and other ingredients, and its meat is soft and easy to digest, it is an excellent food for people who are weak and need to take care of after illness; shrimp is rich in magnesium, which plays an important role in heart activity. It can reduce the content of cholesterol in the blood and prevent arteriosclerosis. [0003] If the shrimps are not handled in time after being caught, they will easily lose their umami taste and d...
