Embodiment 1

[0013] A biological antibacterial agent, comprising ε-polylysine, nisin, wood vinegar, ethanol and water, the mass fractions of each raw material are as follows: 0.1 part of ε-polylysine, 0.1 part of nisin , 0.2 parts of wood vinegar, 60 parts of ethanol and 39.6 parts of water.

Embodiment 2

[0015] A biological antibacterial agent, comprising ε-polylysine, nisin, wood vinegar, clove essential oil, ethanol and water, the mass fractions of each raw material are as follows: ε-polylysine 0.05 part, lactococcus 0.03 parts of vegetable, 0.2 parts of wood vinegar, 0.02 parts of clove essential oil, 50 parts of ethanol, and 49.7 parts of water.

Embodiment 3

[0017] A biological antibacterial agent, comprising ε-polylysine, nisin, wood vinegar, clove essential oil, ethanol and water, the mass fractions of each raw material are as follows: 0.5 parts of ε-polylysine, lactic acid streptococcus 0.3 parts of vegetable, 0.8 parts of wood vinegar, 0.1 parts of clove essential oil, 40 parts of ethanol and 58.3 parts of water.

[0018] Utilizing the biological bacteriostatic agent prepared in Example 1-3, the biological bacteriostatic agent only needs to act for 3-5 minutes, and has good antibacterial effect on Escherichia coli, Staphylococcus aureus, Aspergillus niger, Candida albicans, etc. The antibacterial rate reaches more than 99%. The finished biological bacteriostatic agent prepared in Examples 1-3 is liquid, and can be used for spraying and disinfecting raw material warehouse environment and equipment, production workshop environment and equipment, etc. in beverage processing industry and food processing industry, and can also be u...

Abstract

The invention provides a biological bacteriostatic agent. The biological bacteriostatic agent comprises the following raw materials in parts by mass: 0.01-5 part of epsilon polylysine, 0.01-2 parts ofnisin, 0.05-4 part of pyroligneous liquor, 10-60 parts of ethanol and 10-90 parts of water. The above components in the biological bacteriostatic agent are environmentally friendly and harmless to people and livestock; the biological bacteriostatic agent is free of residues, does not need to be washed with water after being disinfected and sterilized, is convenient to use and has a good bacteriostatic effect and a broad-spectrum bactericidal effect; the epsilon polylysine in the agent is rich in cations, has strong electrostatic acting force on substances with anions and has good penetratingpower to biological membranes; and the main component of the pyroligneous liquor is acetic acid, and after the epsilon polylysine is mixed with ethyl alcohol and acetic acid, the sterilization capacity of epsilon polylysine can be greatly improved.

Description

technical field [0001] The invention specifically relates to a biological antibacterial agent. Background technique [0002] Bacteriostatic agents are substances that inhibit the growth of bacteria. Bacteriostatic agents may not kill bacteria, but they can inhibit the growth of bacteria and prevent excessive bacterial growth and endanger health. Chemical bacteriostatic agent is a commonly used type of bacteriostatic agent. Chemical bacteriostatic agent has a certain effect in inhibiting the reproduction of bacteria and molds, but the toxic chemical substance residue contained in chemical bacteriostatic agent will cause certain damage to human health. influences. With the continuous improvement of people's safety awareness, the impact of chemical bacteriostatic residues has also received more and more attention. In order to find solutions, biological bacteriostatic agents that can replace chemical bacteriostatic agents have gradually received more attention and application. ...
