Abstract

The invention relates to the technical field of food processing and storage and discloses a protective agent composition for liquid nitrogen cryogenic quick-freezing of camarons. The protective agent composition comprises a low-temperature protective agent for soaking the camarons before liquid nitrogen quick-freezing, and an ice glazing agent for soaking the camarons after liquid nitrogen quick-freezing. The low-temperature protective agent comprises sodium polyphosphate, sodium erythorbate, sodium citrate, sorbitol, bletilla extracts and water. The ice glaze agent comprises trehalose, sodium alginate, bletilla extracts and ice water. The protective agent composition comprises the low-temperature protective agent and the ice glaze agent and is matched with the liquid nitrogen cryogenic quick-freezing method, ice crystals formed by products subjected to cryogenic quick-freezing are small, the drying loss is low, the integrity of product cells is guaranteed, the original color, freshness and flavor can be maintained, the shelf life of the products is greatly prolonged, and the freshness preservation degree is high.

Description

technical field [0001] The invention relates to the technical field of food processing and storage, in particular to a protective agent composition for cryopreservation and quick freezing of monodon shrimp. Background technique [0002] Spotted prawns, also known as bamboo prawns, tiger prawns, grass prawns, black tiger prawns, and flower prawns, are marine shrimps with high nutritional value and certain health care functions, and are of great development and utilization value. The distribution area is very wide, from southern Japan, South Korea, the coast of my country, the Philippines, Indonesia, Australia, Thailand, India to the east coast of Africa. Compared with some other aquatic products, it is easy to be spoiled and deteriorated during fishing, transportation, processing and storage. Shrimp usually dies soon after fishing. If the distance between the points is relatively long, it will be difficult to keep fresh, which seriously affects the quality of the lobster. W...
