Problems solved by technology

[0003] At present, there are many methods about the composite film-forming fresh-keeping technology. The prior art, such as the Chinese invention patent whose authorized public number is CN102259965 B, discloses a large yellow croaker composite film-forming preservative and its preparation method. The advantage of being simple, but it does not have the effect of removing fishy smell, and it is only a simple combination of several fresh-keeping substances, and the fresh-keeping effect is not strong. Because it is a special preservative for large yellow croaker, it is not suitable for other aquatic products, so it does not have a high economic outlook

Abstract

A composite film forming fresh-keeping agent is disclosed. The composite film forming fresh-keeping agent includes, by weight, 1.5-2 parts of carboxymethyl chitosan, 1.5-2 parts of sodium alginate, 2-3 parts of tea polyphenols, 0.5-0.6 part of epsilon-polylysine, 0.2-0.3 part of VC, 0.05-0.06 part of nanometer TiO2, 2-2.6 parts of bone polypeptides, 0.15-0.2 part of nisin, 0.3-0.5 part of sodium phytate, 0.3-0.5 part of sodium sorbate, 0.5-0.8 part of a fishy flavor removing agent, 0.3-0.6 part of a plant extract, 1.2-1.5 parts of a film forming agent, 0.5-0.6 part of an emulsifier and 90-100 parts of distilled water. Beneficial effects of the composite film forming fresh-keeping agent are that the composite film forming fresh-keeping agent is simple to prepare, has good film forming effects and a high film forming speed, and has strong effects of removing fish flavor, achieving bacteriostasis, preventing oxidation, inhibiting enzyme activity, delaying a situation that the pH of fish reaches a pH limit, and the like, and the composite film forming fresh-keeping agent is capable of removing fishy flavor, high in efficiency, safe, and free of toxic and side residues.

Description

technical field [0001] The invention relates to the field of antistaling agents, in particular to a composite film-forming antistaling agent. technical background [0002] Fish is rich in protein, fat, vitamins and minerals, etc. It can provide the human body with a variety of amino acids, vitamins and unsaturated fatty acids, and has a good health care effect. Fish is rich in minerals. Every 100 grams of sea fish contains 310 mg of phosphorus, 35 mg of calcium, 300 mg of potassium, 90 mg of sodium, 200 mg of sulfur and 120 mg of chlorine. Fish and other aquatic products are delicious and nutritious, and have become an important part of the human diet. Compared with livestock and poultry on land, fish are more prone to corruption due to their habitat, fishing methods, and their own characteristics. First, the environment in which fish live (oceans, rivers, lakes, ponds, etc.) is easily polluted to contaminate microorganisms. Secondly, it is easy to cause fish death and inj...
