Abstract

The invention discloses a fresh shrimp cryoprotectant and a cryopreservation method, and belongs to the technical field of aquatic product preservation. The cryoprotectant comprises the following rawmaterials in parts by weight: 3-6 parts of trehalose; 2-3 parts of xylooligosaccharide; 1-2 parts of lactitol; 0.8-1.5 parts of konjac glucomannan; 0.5-1 part of D-glucosamine hydrochloride; and 2-5 parts of p-hydroxycinnamic acid. The method comprises the following steps: pretreating fresh shrimps, soaking the pretreated shrimps in a cryoprotectant solution, and conducting cryopreservation. The cryoprotectant can effectively reduce mechanical damage to muscle tissues of the fresh shrimps in the freezing process, reduce lipid oxidation and protein denaturation, improve water retention, well maintain cell integrity, improve the quality of the frozen fresh shrimps and meet the requirements of consumers.

Description

technical field [0001] The application relates to the technical field of aquatic product storage, in particular to a fresh shrimp cryoprotectant and a frozen storage method. Background technique [0002] Our country is rich in seafood resources. Every year, river prawns and sea prawns have a large output. Shrimp is rich in nutrients, and its protein content is several to dozens of times that of fish, eggs, and milk; it is also rich in potassium, iodine, magnesium, Phosphorus and other minerals, vitamin A, aminophylline and other ingredients, and its meat is soft and easy to digest, and it is an excellent food for people who are weak and need to take care of themselves after illness; shrimp is rich in magnesium, which has a positive effect on heart activity. Important regulation, can reduce blood cholesterol levels, prevent arteriosclerosis and so on. However, fresh shrimp is restricted by various factors such as fishing season, geographical conditions, and climate. During s...
