Abstract

The invention relates to a biological-source nutritional preservative for seafood. The biological-source nutritional preservative is characterized in that each liter of the distilled water of the biological-source nutritional preservative contains 0.4-0.6g of lysozyme, 2.5-3.5g of tea polyphenols, 20-28g of carboxymethyl chitosan, 10-14g of nisin, 17-23g of sodium alginate, 20-30g of lactobacillus, 1.5-2.5g of propolis extract and 10-14g of spice extract, wherein the spice extract is made of rhizoma galangae, garlic, onion, cinnamon, clove and rosemary. The biological-source nutritional preservative has the advantages that the biological-source nutritional preservative is compound by biological preservatives and is safe, nontoxic, simple in preparation and application method, outstanding in microorganism inhibition effect, good in preservation effect, capable of greatly prolonging the shelf life of the seafood and high in industry value.

Description

technical field [0001] The invention relates to a biologically sourced seafood nutritional preservative, which belongs to the technical field of seafood preservation, and in particular relates to a compounded biological preservative, which is safe and non-toxic, has simple preparation and application methods, outstanding effect of inhibiting microorganisms, and good freshness preservation effect. It can greatly prolong the shelf life of refrigerated seafood, and is a biologically sourced seafood nutritional preservative with important industrial value. Background technique [0002] Seafood is everyone's favorite food. Fresh small seafood is not only delicious, but also has more practical significance from the perspective of health care. It is rich in high-quality protein (mainly myosin that is easy to digest and absorb), rich in minerals and trace elements, A variety of fat-soluble vitamins and antioxidants. High-quality protein can repair aging and damaged tissue cells of...
