Composite water-retaining agent for aquatic products

Abstract

The invention relates to a composite water-retaining agent for aquatic products. The composite water-retaining agent is prepared by mixing the following raw materials in parts by weight: 30-50 parts of protease, 1-3 parts of food acidity regulator, 20-30 parts of antioxidant, 2-4 parts of mannitol, 0.5-3 parts of softening agent, 10-15 parts of sodium alginate, 1-3 parts of lactitol and 2-4 parts of glycine. The product is white odourless powder, is soluble in water, is alkaline and is safe, non-toxic and harmless to use. The composite water-retaining agent is mainly used in the aquatic products to retain water, retain freshness, prevent decay, absorb water and increase the weight. After the composite water-retaining agent is added, the stability of the products can be improved, the water binding capacity inside food can be maintained, meat can be tenderized, the cooking time can be shortened, and the shape, flavor, taste and color of food can be improved.

Description

technical field [0001] The invention belongs to a functional polymer material in the fine chemical industry, in particular to a composite water-retaining agent for aquatic products. Background technique [0002] Water retaining agent is a new type of functional polymer material developed in recent years, which has excellent water absorption and water retention properties. The water-retaining agent has a particularly strong water-absorbing ability, which can absorb water hundreds to thousands of times its own weight, and forms a gel after absorbing water and swelling. At present, the preservation of aquatic products mainly depends on freezing, but after freezing, the weight of shrimp will be reduced, the color will be changed, and the protein content will be oxidized. For this reason, people need to use water-retaining agents to maintain the quality of frozen aquatic products, resist oxidation, improve texture, and stabilize color. However, the currently used water-retaining...

Problems solved by technology

For this reason, people need to use water-retaining agents to maintain the quality of frozen aquatic products, resist oxidation, improve texture, and stabilize color. However, the currently used water-retaining agents contain phosphates, which are unsafe and unstable to use.
