Embodiment 1

[0050] see figure 1 , a biological composite antistaling agent for aquatic products, the composite antistaling agent comprises the following components by weight:

[0051] 30-40 parts of antioxidant peptide, 20-30 parts of garlic powder, 20-30 parts of ginger extract, 20-30 parts of mugwort leaf extract, 10-20 parts of chitosan derivatives, 10-20 parts of citric acid, tea 10-20 parts of phenol, 300-400 parts of deionized water.

[0052] Wherein, the preparation process of the antioxidant peptide is as follows:

[0053] Take the cleaned grouper and salmon processing by-products, mash the tissue and homogenate the homogenate, and set aside;

[0054] Add isopropanol to the above homogenate according to the ratio of solid to liquid 1:6-9g / mL, stir and degrease at 35-40°C for 20-40h, then centrifuge at 4000-6000rpm for 15min, filter off the supernatant and collect the defatted solid precipitation;

[0055] Add 0.5mol / L phosphate buffer solution to the above-mentioned degreased ...

Abstract

The invention discloses a biological compound preservative for aquatic products and a preservation method thereof. The invention belongs to the technical field of aquatic product biological storage. The biological compound preservative for aquatic products comprises antioxidant peptide, garlic powder, a fresh ginger extracting solution, a folium artemisiae argyi extracting solution, a chitosan derivative, citric acid, tea polyphenol and other components. The biological compound preservative for aquatic products has the characteristics of no toxicity, no residue, low cost, safety, reliability and the like, can effectively prevent fat, protein and the like of the aquatic product from being damaged by oxidation, can reduce the requirement on a storage temperature of the aquatic product, and obviously prolongs the storage period. The raw materials are wide in source, easy to obtain and low in cost. The biological compound preservative is wide in an application range.

Description

technical field [0001] The invention relates to the technical field of biological storage of aquatic products, and more specifically relates to a biological composite fresh-keeping agent for aquatic products and a fresh-keeping method thereof. Background technique [0002] Aquatic products have high nutritional value and delicious taste, and are deeply loved by consumers. With the rise of the domestic aquaculture industry, the scale of aquaculture is getting larger and larger, and people's requirements for the quality of aquatic products are also getting higher and higher. Due to the characteristics of high protein content, highly unsaturated fat and loose tissue structure, aquatic products are more likely to be oxidized than livestock and poultry meat; oxidation of aquatic products after capture and processing can easily lead to protein decomposition of fish meat, resulting in bad fish meat. At the same time, there are many kinds of microorganisms that cause fish body spoil...
