Problems solved by technology

[0004] At present, there are many methods for fresh-keeping technology of hairtail. The prior art, such as the Chinese invention patent with authorized public number CN 103689062B, discloses a fresh-keeping agent for hairtail, its preparation method and its use method. The process is simple and convenient, but it is only a simple proportion of several plant extracts, so its fresh-keeping effect is limited, and the advantages of no residue and high safety of biological preservatives have not been exerted

Abstract

The invention discloses a biological fresh-keeping agent for hairtail. The biological fresh-keeping agent contains the following components in parts by weight: 5-8 parts of tea polyphenol, 2-4 parts of allicin, 3-5 parts of chitosan, 3-5 parts of vitamin E, 0.4-0.5 part of vegetable acid, 2-4 parts of bioenzyme, 2-4 parts of an active peptide ferrous chelate and 100-120 parts of distilled water. Active peptide is prepared through fermentation of actinomycetes and is purified through centrifugation and ammonium sulfate precipitation, and then the active peptide ferrous chelate is prepared. The biological fresh-keeping agent has the beneficial effects that the biological fresh-keeping agent has excellent effects of killing bacteria, resisting oxidation, inhibiting enzymatic activity and the like, the fresh-keeping limit of the hairtail can be prolonged from several days to 40-60 days, so that the fresh-keeping agent is very good; and by utilizing the active peptide ferrous chelate capable of scavenging free radicals, the fresh-keeping agent has extremely strong oxidation resistance, so that the biological fresh-keeping agent is safe, non-toxic and efficient, the original quality of the hairtail is well maintained, and the shelf life of the hairtail can be remarkably prolonged.

Description

technical field [0001] The invention relates to the field of preservatives, in particular to a biological preservative for hairtail. technical background [0002] Hairtail belongs to the Osteophyta Perciformes Hairtail family in the subphylum Vertebrate under the phylum Chordate, also known as saury, crony, fat belt, oil belt, octopus, etc., and is ferocious. Hairtail has thick thorns and few thorns, and is rich in nutrition. In every 100 grams of hairtail meat, there are 19 grams of protein and 7.4 grams of fat. Hairtail is a high-fat fish, containing protein, fat, vitamin B1, B2, niacin, calcium, phosphorus, iron, iodine and other ingredients. Hairtail fish scales also contain a variety of unsaturated fatty acids, fibrous substances, 6-thioguanine and other active ingredients, among which fibrous substances can inhibit cholesterol and can also fight cancer. Hairtail meat has the effects of nourishing the spleen, nourishing qi, warming the stomach, nourishing the liver, ...
