Phosphorus-free squid water-retaining agent and application thereof

Abstract

In order to enhance the water-holding capacity of squid in the storage process, the invention provides a phosphorus-free squid water-retaining agent and application thereof, and belongs to the technical field of aquatic product processing. The specific scheme is as follows: the phosphorus-free squid water-retaining agent includes 1-3 parts of a water-retaining expander, 2-4 parts of a water-retaining synergist and 4-8 parts of a strengthening water-retaining agent. The water-retaining expander is a monosaccharide derivative or / and an oligosaccharide derivative; the water retaining synergist isa neutral salt or / and a salt of weak acid and strong alkali, and the strengthening water-retaining agent is oligosaccharide or / and water-soluble polysaccharide. The application method is as follows:the water-retaining agent is prepared into 1.0%-2.0% of a water solution according to the above proportioning ratio, and a squid raw material is immersed in the water-retaining agent solution. The squid products treated by the application method of the water-retaining agent recorded in the present invention are frozen for 3 months, after being thawed by refrigerated air, the squid products are glossy in the surface, and have no wrinkles, elastic texture, and good taste and no odor after cooking.

Description

technical field [0001] The invention belongs to the technical field of aquatic product processing, and in particular relates to a phosphorus-free squid water retention agent and its application. Background technique [0002] The scientific name of squid is Chinese calamari ( Loligo chinensis ), belonging to the phylum Molluscs, Cephalopoda, Dibranchia, and Decabrachia. In recent years, as the world's pelagic marine biological resources are decreasing day by day, squid has gradually become an important protein resource for human beings because of its delicious taste and rich nutrition. my country's ocean fishing industry is developing rapidly. Squid has become my country's main ocean fishing and aquatic product processing raw material. The catch accounts for more than 40% of the country's total ocean fishery output. The squid processing industry has become an important part of my country's aquatic product processing industry. Squid has high protein content, low fat content,...

Problems solved by technology

Although phosphate has good water retention, excessive addition will deteriorate the flavor and color of aquatic products. Excessive intake of the human body will lead to calcium and phosphorus imbalance and cause diseases. As people pay more and more attention to food safety issues, phosphate is often used Compound with carbonate to partially replace phosphate or directly use phosphorus-free, safe water retaining agent

[0006] 2. Phosphate-free salt water-retaining agent: Phosphorus-free salts with water-retaining effects such as sodium chloride, sodium carbonate, sodium bicarbonate, sodium citrate and other non-phosphorus salts are rarely used alone for water retention in aquatic products. Composite technology, but the effect is not as good as phosphorus-containing water retaining agent

However, polysaccharides have poor solubility and diffusibility, poor binding ability with squid protein, and it is difficult to maintain water retention stably
