Embodiment 1

[0018] Embodiment 1: a kind of biological antistaling agent, it is made up of chitosan, cecropin, tea polyphenol and water, and its proportioning by weight is: chitosan 2-6, cecropin 0.2-0.6, tea polyphenol 2 -6, water 1000.

[0019] A biological antistaling agent, which is composed of chitosan, cecropin, tea polyphenol and water, and its proportion by weight is: chitosan 6, cecropin 0.4, tea polyphenol 2, water 1000.

[0020] A fresh-keeping method, comprising the following steps:

[0021] Step 1: Take the fresh fish body, remove the head and tail, clean it, cut it into sections or slice it for later use;

[0022] Step 2: Put the sectioned or sliced ​​fish into the container filled with the above-mentioned biological preservative and soak for 5 minutes, then take it out immediately, then place it on another empty tank plate to drain, and recycle the excess biological preservative that flows down;

[0023] Step 3: After the biological preservative is basically drained, pack ...

Abstract

The invention provides a biological preservative and a preserving method thereof. The preservative is prepared from the following components in parts by weight: 2-6 parts of chitosan, 0.2-0.6 part of cecropin, 2-6 parts of tea polyphenol and 1000 parts of water. The biological preservative has the beneficial effects of no toxicity, no odor and low cost, and has excellent dispersion, moisture retention, film-forming property and antibacterial property.

Description

technical field [0001] The invention relates to a biological antistaling agent and a fresh-keeping method which can enhance the fresh-keeping time by more than 40%, have good quality control, have no side effects on the human body, and have certain nutritional strengthening and health-care effects. Background technique [0002] Aquatic products are one of the main sources of human high-quality protein, rich in 8 kinds of amino acids necessary for the human body. Fish body fat is rich in EPA, DHA, multivitamins, minerals and lecithin, which have important physiological functions. However, as a general characteristic of aquatic products, fish has high water and protein content, soft tissue, and it is easy to carry a large number of bacteria. It is easy to be spoiled by bacteria and enzymes during fishing, transportation, processing, storage and sales. , and prone to fat oxidation and rancidity, causing discoloration, odor, and even spoilage, which greatly reduces the edible v...
