Abstract
The invention relates to a formula of an aquatic product composite preservative. The formula of the aquatic product composite preservative is characterized in that the aquatic product composite preservative in each liter of distilled water comprises the following components: 0.4 to 0.6 g of muramidase, 2.5 to 3.5 g of tea polyphenol, 16 to 20 g of carboxymethyl chitosan, 10 to 14 g of nisin, 25 to 35 g of potassium sorbate, 17 to 23 g of sodium alginate, 20 to 30 g of lactobacillus, 1.5 to 2.5 g of propolis extracts and 10 to 14 g of spice extracts; and the spice extracting liquid comprises the raw materials: galangal, garlic, onion, cinnamon, clove and rosemary. The aquatic product composite preservative provided by the invention is prepared by compounding biological preservatives, is safe and non-toxic, has simple preparation and application methods, prominent microbial inhibition effect and good preservation effect, can greatly prolong the shelf life of frozen aquatic products, and has important industrial value.
Description
technical field [0001] The invention relates to a formula of a composite preservative for aquatic products, which belongs to the technical field of fresh-keeping of aquatic products, 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 fresh-keeping effect. It can greatly prolong the shelf life of refrigerated aquatic products, and is a compound preservative formula for aquatic products with important industrial value. Background technique [0002] With the growth of the world's population, food supply requires not only security in quantity, but also higher and higher requirements for food quality, texture, nutrition, flavor and shelf life. Compared with livestock and poultry foods, aquatic foods are recognized globally as high-protein, low-fat "white meat". my country is the country with the largest production and consumption ...
