Abstract

The invention discloses an alcohol disinfectant for food contact, and belongs to the field of chemical products. The disinfectant is a chemical preparation used for killing pathogenic microorganisms on a transmission medium and achieving the purpose of controlling infectious diseases by harmless requirements. The existing domestic disinfectant generally cannot disinfect food directly due to certain toxicity, and about 75% of high-degree white spirit in the market does not qualify as a disinfectant product. The invention eliminates the toxic chemical components of the ethanol disinfectant, blends high-concentration edible ethanol into the disinfectant with the concentration range of 60-85% (volume ratio), meets the requirements of the public food application disinfection market, for example, the invention is used for sealing after food, beverage and the like are unsealed, and the standing time can be greatly prolonged. According to different demand groups, additives such as smell, taste, color and the like which meet the requirements of food sanitation, disinfectant products and the like can be properly added to develop different alcohol disinfectants based on the basic functions of the alcohol disinfectants.

Description

Alcohol disinfectant for food contact

Technical Field

The invention discloses an alcohol disinfectant for food contact, and belongs to the field of chemical products.

Background

The disinfectant is a chemical preparation used for killing pathogenic microorganisms on a transmission medium and achieving the purpose of harmlessly requiring infectious disease control. The disinfectant can be divided into 9 types according to chemical components: chlorine-containing disinfectants, peroxide disinfectants, aldehyde disinfectants, alcohol disinfectants, iodine-containing disinfectants, phenol disinfectants, ethylene oxide, biguanide disinfectants and quaternary ammonium salt disinfectants; at present, the domestic disinfectant is mainly produced by chlorine-containing disinfectant, alcohol-containing disinfectant, aldehyde-containing disinfectant, iodine-containing disinfectant and phenol disinfectant. Classified according to disinfection intensity, the chlorine-containing disinfectant peroxide (hydrogen peroxide, peroxyacetic acid), glutaraldehyde, dibromohydantoin and the like are taken as representatives; the intermediate disinfectant is represented by alcohols (alcohol and isopropanol), iodine preparations (iodophor and iodine tincture), phenol disinfectant (methyl phenol and parachlorometaxylenol) and compound disinfectant (generally 75% ethanol is used as a mixture); low-efficiency disinfectants are represented by quaternary ammonium disinfectants (benzalkonium bromide, benzalkonium chloride) and biguanide disinfectants (chlorhexidine). Among the disinfectants, iodine-containing disinfectants among halogen disinfectants are commonly used in medical surgery, and sodium hypochlorite is commonly used in environmental disinfection; the aldehyde disinfectant is commonly used for disinfecting the environment in a clean area of a pharmaceutical enterprise, and cannot be used for air and food; the peroxide disinfectant is suitable for disinfecting the surface of an object, indoor air, skin wounds and corrosion-resistant medical instruments; alcohol disinfectant is mainly used for hands and skin, such as medical alcohol (70% -75%) and isopropanol; guanidine disinfectants and quaternary ammonium salt disinfectants belong to low-efficiency disinfectants and are commonly used in food industry, drinking water, household detergents and the like; the phenol disinfectant is commonly used for disinfection, clinical disinfection, antisepsis and the like of an empty room; ethylene oxide based disinfectants are commonly used for metal articles, endoscopes, dialyzers, disposable medical devices, and the like. Except the guanidine disinfectant and quaternary ammonium salt disinfectant, which are commonly used in food industry, drinking water, household detergent and the like, the existing disinfectant can not be used in food industry, wherein the medical disinfectant contains toxic components such as formaldehyde and the like, and can not be used in food. Even guanidine disinfectants and quaternary ammonium disinfectants are only used for disinfecting food industry equipment and the like, and do not contact with food. All the disinfectants cannot directly disinfect food because of certain toxicity, and cannot meet the rising demand of the public on food contact application disinfection markets. In addition, about 75% of high-degree white spirit exists in the market, belongs to the food and beverage industry, does not qualify as a disinfectant product, and is relatively high in cost.

Disclosure of Invention

The invention can blend high-concentration edible alcohol (high-purity edible ethanol) into the disinfectant with the concentration range of 60-85% (volume ratio) by eliminating toxic chemical components of the ethanol disinfectant, such as toxic chemical components in medical alcohol and maintaining the disinfection effect of about 75% (volume ratio) of ethanol, thereby meeting the increasing demand of the public in the food application disinfection market; the invention can be used for regularly sterilizing the spaces such as refrigerators for placing food; the invention can be used for sterilizing cooked food before being covered with the preservative film so as to prolong the standing time and the like; the invention can be used for sterilizing the food before sealing the cover so as to eliminate the air environmental pollution of restaurant kitchens and the like; meanwhile, according to different demand groups and application scenes thereof, a plurality of additives with smell, taste, color and the like which meet the requirements of food sanitation, disinfectant products and the like can be properly added, and various different alcohol disinfectants based on the basic functions of the food-grade disinfectants are developed.

Detailed Description

The first implementation method of the invention is as follows:

according to the related studies, alcohol solutions with concentrations higher than 60% (volume ratio) have a disinfecting effect, and alcohol concentrations of 60% to 80% (volume ratio) can destroy the cell wall/membrane of bacteria (effective for most bacteria, fungi and some viruses, ineffective for bacterial spores) by denaturing proteins and dissolving their lipids. The finished product of edible alcohol is detected by a manufacturer which meets the requirements of national sanitary and health standards and has the production and management qualification of disinfectant products, the non-ethanol component is removed by a purification process, and the disinfectant with the concentration of about 60-85% (volume ratio) is blended.

The second implementation method of the invention is as follows:

according to the related studies, alcohol solutions with concentrations higher than 60% (volume ratio) have a disinfecting effect, and alcohol concentrations of 60% to 80% (volume ratio) can destroy the cell wall/membrane of bacteria (effective for most bacteria, fungi and some viruses, ineffective for bacterial spores) by denaturing proteins and dissolving their lipids. Detecting the finished product of edible alcohol in a manufacturer meeting the requirements of national sanitary and health standards and having the production, operation and qualification of disinfectant products, removing non-ethanol components by a purification process, and blending the disinfectant with the concentration of about 60-85% (volume ratio); meanwhile, according to different demand groups and application scenes thereof, a plurality of additives with smell, taste, color and the like which meet the requirements of food sanitation, disinfectant products and the like can be properly added, and various different alcohol disinfectants based on the basic functions of the food-grade disinfectants are developed.

Claims

1. An alcohol disinfectant for food contact, which is characterized by comprising the following steps:

2. An alcohol disinfectant for food contact, which is characterized in that the implementation method II comprises the following steps:
