Abstract

The invention relates to a preparation method of a nano water-retaining agent and application of the nano water-retaining agent in quick-frozen crustacea shrimp products and belongs to the technical field of food processing. The nano water-retaining agent comprises inulin, xylitol, carboxymethyl chitosan, pullulan, sodium tripolyphosphate, sodium chloride and sodium alginate. The preparation method includes: evenly mixing the powdered raw materials with water, processing the mixture with a homogenizing machine and a colloid mill, and performing ultrasonic treatment to obtain the nano water-retaining agent. The invention further relates to application of the anti-freezing water-retaining agent in the freezing of crustacea aquatic products. Compared with the prior art, the nano water-retaining agent has the advantages that the nano water-retaining agent can effectively prevent the albuminous degeneration and oxidation of the crustacea aquatic products during freezing, the water-retainingcapacity and nutritional value of the crustacea aquatic products can be kept to the maximum extent, the water loss rate of the crustacea aquatic products in the quick-frozen period of six months is below 10%, and a good economic value is achieved.

Description

technical field [0001] The invention relates to the preparation and application of a nano water-retaining agent for crustacean aquatic products, and belongs to the technical field of food processing. Background technique [0002] Crustaceous aquatic products have the characteristics of high protein and high moisture, and are prone to spoilage and deterioration under the action of oxidation reactions, microorganisms and endogenous enzymes, resulting in a decline in edible quality and a reduction in economic value. At present, its sales mainly include fresh sales and frozen sales. Although live sales can maximize the quality of crustacean aquatic products, due to seasonal and regional restrictions, fresh sales are limited to specific regions and seasons. , For products that are produced in the off-season or exported to foreign countries, frozen sales are often used. Cryopreservation can maximize the nutritional value of crustacean aquatic products, but the ice crystals produc...
