Problems solved by technology

In the field of food production and disinfection, the main disadvantages of chemical disinfectants represented by sodium hypochlorite are poor stability, short shelf life, oxidative decolorization and denaturation of food, severe corrosion to metals, irritation to human skin, and chemical reactions in the environment or food. Organic chlorine, such as chloroform, has been proved by medical experiments to be the cause of tumors. The future development trend will definitely be that chemical disinfectants are gradually replaced by biological disinfectants. Compared with traditional chemical disinfectants, they have strong bactericidal specificity and are not Residual harmful substances, non-flammable, safe to use, etc.
Biological disinfectant is a new type of disinfectant, and its application research is still in its infancy, and there is currently no biological disinfectant used in the field of food production

Abstract

The invention discloses a biological disinfectant in a food field. The biological disinfectant belongs to the field of food disinfection, and comprises the following components in part by weight: 0.5 to 1 part of sodium dichloro cyanurate, 5 to 10 parts of tween-20, 1 to 5 parts of ethylenediaminetetraacetic acid, 1 to 10 parts of compound phosphate, 5 to 10 parts of ethanol, 100 parts of distilled water, and 5 to 10 parts of sorbitol. The biological disinfectant also comprises 0.01 to 0.1 weight percent of lysozyme. The biological disinfectant in the food field has the advantages of strong sterilization specificity, mild working conditions and quick effect, and drug resistance of strains can be prevented. The biological disinfectant is soluble in water, does not irritate articles, and can be used safely. Particularly, the biological disinfectant does not produce harmful substance residues in food. The biological disinfectant, which is simple in preparation, is applied to the surface disinfection and cleaning of the food processing equipment, food equipment and food processing environment, and fruits and vegetables and common articles in household life.

Description

technical field [0001] The invention relates to a disinfectant in the field of food, in particular to a disinfectant which utilizes the combination of biological disinfection and chemical disinfection. Background technique [0002] Most microorganisms can produce lysozyme, and lysozyme can be divided into two categories according to its target, namely, bacterial lysozyme and fungal lysozyme. Bacterial lysozymes can generally be divided into three major categories: N-acetylhexosaminidases, which catalyze the hydrolysis of β(1→4) glycosidic bonds in the sugar backbone of peptidoglycan; N-acetylmuramoyl-alanine amide Enzymes, which catalyze the cleavage of sugar and peptidyl groups in peptidoglycan; endopeptidases, which catalyze the cleavage of peptide bonds in peptidoglycan peptide bridges. Fungal lysozymes mainly include chitinase and -β-glucanase. [0003] Lysozyme itself is a non-toxic, harmless, high-safety high-salt-based protein, which can selectively decompose the ce...
