Description

Technical Field

[0001] The present invention relates to the technical field of bactericidal disinfectants, and in particular to a high-efficiency food-grade bactericidal disinfectant and a preparation method thereof. Background Art

[0002] With the improvement of people's living standards and life concepts, hygiene awareness is also constantly increasing. People pay more attention to hygiene in their daily lives, and the application of cleaning and disinfecting agents is becoming more extensive. There are many types of cleaning and disinfecting agents on the market, including those with cleaning and decontamination functions and those with sterilization functions. However, because most of them contain organic solvents and surfactants, and even chemical preservatives and fungicides, their safety and secondary pollution to the environment are increasingly attracting widespread attention.

[0003] Nowadays, with the improvement of people's living standards, people are more inclined to look for a disinfectant that can effectively remove pesticides and bacteria in food, while being stable and pollution-free, so as to meet the needs of food safety in daily life.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems of high pollution and low safety of existing bactericidal disinfectants. The present invention provides a high-efficiency food-grade bactericidal disinfectant and a preparation method thereof. The bactericidal disinfectant does not need to be diluted and can be used directly. It is stable, efficient, ecological, healthy, and has a high sterilization rate.

[0006] In order to achieve the above object, the present invention provides a high-efficiency food-grade bactericidal disinfectant, which is mainly composed of the following components by mass fraction: 10 -3 3-5 parts of ACS dilution solution, 3-8 parts of organic acid, 10-40 parts of peroxide, 0.04-0.06 parts of colloidal silver ion and 45-85 parts of water.

[0007] Preferably, the above-mentioned bactericidal disinfectant is mainly composed of the following components by mass fraction: 10 -3 4 parts of ACS dilution solution (times 1 / 2), 5 parts of organic acid, 30 parts of peroxide, 0.05 parts of colloidal silver ion and 60.95 parts of water.

[0008] Preferably, the above-mentioned bactericidal disinfectant is mainly composed of the following components by mass fraction: 10 -3 4 parts of ACS dilution solution (times 1 / 2), 6 parts of organic acid, 25 parts of peroxide, 0.05 parts of colloidal silver ion and 64.95 parts of water.

[0009] Preferably, the above-mentioned bactericidal disinfectant is mainly composed of the following components by mass fraction: 10 -33 parts of ACS dilution solution (times 1 / 2), 8 parts of organic acid, 20 parts of peroxide, 0.05 parts of colloidal silver ion and 68.95 parts of water.

[0010] The above-mentioned high-efficiency food-grade bactericidal disinfectant, 10 -3 Acidic calcium sulfate (ACS) reagent was diluted 10 -3 The ACS reagent, purchased from Wudian (Shanghai) Biotechnology Co., Ltd., is primarily composed of sulfuric acid, calcium sulfate, and calcium hydroxide. The calcium sulfate content is 65 ppm, the sulfuric acid is 5.0 ppm, and the calcium hydroxide is 5.0 ppm, resulting in a sulfate mass fraction of 39.7%. The ACS reagent is a slightly soluble acidic solution with an acid equivalent concentration of up to 31N, equivalent to 98% concentrated sulfuric acid (36N). Therefore, ACS can be considered a new type of strong acid water or acidifying agent.

[0011] Preferably, the organic acid is selected from one or more of formic acid, propionic acid, lactic acid and citric acid. The organic acids involved in the present invention are all food-grade organic acids.

[0012] Preferably, the peroxide is selected from one or both of peracetic acid and hydrogen peroxide, and the peroxides involved in the present invention are all food grade peroxides.

[0013] The present invention also provides a method for preparing the above-mentioned high-efficiency food-grade bactericidal disinfectant, comprising the following steps:

[0014] Take 10 -3 Add 100 times the ACS dilution solution, organic acid, colloidal silver ions, peroxide and appropriate amount of water, and stir until mixed evenly.

[0015] Preferably, in the preparation method of the above-mentioned high-efficiency food-grade bactericidal disinfectant, the stirring time is 1-2 hours and the stirring temperature is 20-30°C.

[0016] The present invention dilutes ACS to 10 -3 The purpose of the double is to create a lower pH environment. Adding organic acid in a lower pH environment can enhance the antibacterial and bactericidal ability of the organic acid; mixing colloidal silver ions with food-grade peroxide can enhance the activity of the peroxide. Both of the above actions have a synergistic effect, which can greatly enhance the bactericidal and disinfecting effect of the present invention.

[0017] ACS dilution solution contains high concentration of hydronium ions (H3O + , or H5O2 + , or H7O3 +etc.), which can reduce the dissociation degree of organic acids in the solution or bacterial parasitic environment, and make them more in a non-dissociated state. Organic acids in a non-dissociated state can be absorbed into the cells as nutrients by bacteria through free diffusion, and then dissociate into carboxyl ions and H + , carboxyl ions have the function of inhibiting DNA replication, inhibiting protein synthesis and destroying bacterial cell membranes, thereby inhibiting the production of the next generation of bacteria. + The concentration is relatively low, and the organic acid molecules entering the cell dissociate into H + , so that intracellular H + The concentration increases, which reduces the pH value in the bacterial cell. The physiological regulatory function is forced to start, forcing ATP to hydrolyze and release energy to drive the antiporter to transport excess H + This process continues to deplete the bacterial cell's ATP, effectively destroying its energy supply system, causing metabolic disorders, and rendering the bacteria inactive until they die, thereby extending the storage period of products susceptible to microbial contamination.

[0018] Food grade superoxide in the present invention is a strong oxidant, and the oxygen molecules (nascent ecology oxygen) of release oxidize the enzyme system of microorganism. Wherein silver exists in the form of active colloidal silver ion, and colloidal silver is that the submicroscopic particles of silver metal are colloidal suspension, and colloidal silver ion can stop the decomposition of superoxide as a stabilizing agent, so when the product of the present invention is preserved, colloidal silver ion can play a role as a stabilizing agent. Colloidal silver ion is positive, and most of harmful microorganisms are negative, and the two attract each other. When the product of the present invention contacts with pollutant (organic matter, algae etc.), Ag+ can strongly attract sulfhydryl (-SH) on the protease in the bacterial body, and combine with it rapidly, make protease lose activity, cause bacterial death.

[0019] Colloidal silver ions act as catalysts to activate peroxides and work simultaneously with active peroxides. When in contact with organic matter, an oxygen atom will actively detach from the peroxide molecule, breaking the connection between the colloidal silver ions and the peroxide as a catalyst. The oxygen atoms released in this way have high kinetic energy, so the active oxides (anions, cations) produced also have high kinetic energy, which can more easily break and penetrate the cell walls and cell membranes of microorganisms, enter the cells and cause their key functional components (such as DNA and enzymes) to necrotize, thereby leading to the death of microorganisms. When the bacteria are killed, Ag + After all organic matter has been oxidized by the active peroxides produced, colloidal silver ions once again act as a stabilizer to protect the remaining peroxides.

[0020] The high-efficiency food-grade bactericidal disinfectant of the present invention can irreversibly destroy all components in pathogenic bacteria cells, thereby ensuring thorough sterilization. At the same time, this unique mechanism also ensures that pathogenic bacteria will not develop drug resistance.

[0021] Compared with the prior art, the present invention has the following beneficial effects:
