Description

  The present invention relates to an alcohol disinfectant, and in particular, in the field of foods, it is an antibacterial and antiviral food that is used to prevent bacteria from growing in the food or generating molds. It relates to alcohol sanitizers.

  In human life, a bactericidal agent or a disinfectant is used in order to improve hygiene, improve the surroundings and environment of the human, and eliminate the influence of bacteria. It is also well known to use ethyl alcohol (also simply referred to as “alcohol”) for the purpose of improving the human living environment or for medical purposes. Many very powerful disinfectants have been developed, but these may have a negative effect on humans and cannot be used easily.

  In addition, in human life, food is also essential for maintaining its health, so it is important to prevent the food from being altered or spoiled. Although it is possible to add them, these are related to entering the human body through the mouth, and very strict conditions are required from the viewpoint of safety. For this reason, only a small amount of food that has passed strict safety tests can be added.

Conventionally, alcohol disinfectants containing ethyl alcohol as a component are known as those that can be directly applied to foods. This conventional alcohol disinfectant was a sanitary material intended to kill and remove mold and other germs attached to the object by spraying and applying to the object. Immediately after evaporation, the object began to be contaminated in a general environment and could not retain antibacterial and antiviral properties. Therefore, Patent Document 1 proposes an alcohol sterilizing agent containing alcohol and chitosan and having a continuous sterilizing power.
JP-A-10-114603

  In addition, conventional alcohol sanitizers with antibacterial and antiviral properties have been used in the past to enhance antibacterial and antiviral properties, such as organic acids such as citric acid, malic acid, and fumaric acid, sucrose fatty acid esters, and glycerin fatty acids. Ester, glycerin, etc. are used in large quantities, and after spraying or dipping, these components are deposited on the surface of the food, or the organic acid rusts containers, cooking utensils, etc. There were problems after use such as deposition of deposited components. In addition, the alcohol disinfectant using a large amount of an additive such as an organic acid described above has a problem in that unnecessary acidity, bitterness, etc. are attached to the object, and the flavor is impaired when used for food. .

  The present invention uses the antibacterial and antiviral properties of catechins due to the catechin component derived from tea, and after the instantaneous sterilization treatment with alcohol, the catechin remaining on the surface of the object even after the alcohol is scattered and evaporated It is an invention of a food-use alcohol disinfectant that prevents contamination due to bacterial growth and adherence of viruses.

Conventional alcohol sanitizers with antibacterial and antiviral properties have so far been sprayed with a large amount of organic acids such as citric acid, malic acid, fumaric acid, sucrose fatty acid esters, glycerin fatty acid esters, glycerin, etc. Alternatively, these components are deposited after immersion, causing problems after use, such as rusting the container or cooking utensil that is the object, or attaching unnecessary deposited components, but the present invention has those defects. It is an invention of a food-use alcohol sanitizer that does not occur.
In addition, the alcohol disinfectant using an additive such as an organic acid in a large amount attaches unnecessary acidity, bitterness, etc. to the object, and in the case of use in food, the flavor is impaired. This invention is invention of the food alcohol disinfectant which does not give an unpleasant taste and odor to food.

That is, this invention solved the said subject by the following means.
(1) Alcohol disinfectant, 0.001 to 0.1% by mass of tea extract containing catechin having an ethyl alcohol concentration of 65 to 80% by mass and 40 to 100% by mass, 0.001 to 0.1% by mass of sodium lactate %, Sucrose fatty acid ester 0.001-0.1% by mass, glycerin fatty acid ester 0.001-0.1% by mass, glycine 0.01-0.5% by mass Food-use alcohol sanitizer.
(2) The alcohol sterilizer for food according to (1) above, wherein the catechin contained in the tea extract is an epigallocatechin gallate of 40% by mass or more.
(3) The alcohol sterilizer for food according to (1) or (2), wherein the ethyl alcohol is fermented alcohol using sugar cane as a raw material of 100% by mass.
(4) The food alcohol disinfectant according to any one of (1) to (3), wherein the pH is adjusted from 5.0 to 8.0 in the formulation.
In addition, in the mixing | blending in the alcohol sterilizer for foods of said (1), the remainder is water.

The pH is adjusted with 0.01% by mass or less of an organic acid for the purpose of suppressing color change due to oxidation of tea catechins. Examples of the organic acid include citric acid, malic acid, fumaric acid and the like. The content of sodium lactate is also related to pH.
In this disinfectant, a fragrance, a pigment, a humectant, an oil, a solvent, and a deodorant, which are recognized as safe as food additives, can also be blended.

  According to the present invention, when this food alcohol disinfectant is directly applied to food by spraying or the like, it not only has an effect of immediately sterilizing bacteria on the surface of the food, but also contains catechin contained therein. Since tea extract has antibacterial action and its antibacterial action persists, even if airborne bacteria and mold fall on food, its antibacterial action can prevent its reproduction, Food can be stored safely. Sustains effect without affecting flavor and properties.

  In order to achieve sterilization and virus elimination, the concentration of alcohol is set to the highest sterilization effect to effectively reduce the contamination of the object instantaneously, and then to maintain a hygienic state, It is a food-use alcohol disinfectant comprising tea extract containing 40 to 100% by mass of catechin as a main antibacterial and antiviral component. This alcohol disinfectant is sprayed directly on foods and does not affect the flavor and properties, and maintains its effect.

  The reason why the concentration of ethyl alcohol is set as high as 65 to 80% by mass in the disinfectant of the present invention is to exhibit an instantaneous disinfecting effect on the food surface when it is injected into the food. Moreover, since the tea extract containing catechin utilizes the antibacterial action by catechin, a tea extract having as high a purity as possible is preferable.

  In order to be able to spray directly on foods, it is necessary to use all materials that meet the food additive standards. The alcohol concentration is set to 65 to 80% by mass in order to exert an instantaneous bactericidal effect, and a tea extract containing 40 to 100% by mass of high purity catechin and epigallocatechin gallate to enhance antibacterial and antiviral properties. use. Strong sterilization and antibacterial based on alcohol, tea extract, small amount of sucrose fatty acid ester, glycerin fatty acid ester, glycine, moisturizing sodium lactate, without relying on antibacterial effects of organic acids such as citric acid and fumaric acid Have antiviral properties. Since an excessive food additive was not used, there was no generation of unnecessary precipitation components, no flavor problems such as acidity and bitterness, and the composition was not affected.

  The alcohol disinfectant of the present invention preferably contains 0.001 to 0.1% by mass of a tea extract containing 40 to 100% by mass of catechin, and this component has an antibacterial action. It is preferable to contain 0.001-0.1 mass% of sodium lactate, and this component acts as a moisturizing agent. It is preferable that 0.001-0.1 mass% of sucrose fatty acid ester is contained, and this component acts as a bacteriostatic. The glycerol fatty acid ester is preferably contained in an amount of 0.001 to 0.1% by mass, and this component acts as a bacteriostatic. Glycine is preferably contained in an amount of 0.01 to 0.5% by mass, and this component acts as a bacteriostatic.

  In order to achieve sterilization and virus removal action, by setting the alcohol concentration to the highest sterilization effect, the contamination of the object is effectively reduced instantaneously, and then the hygienic state is maintained. A food-use alcohol disinfectant comprising a tea extract containing 40 to 100% by mass of catechin as a main antibacterial and antiviral component. Sprays directly on food and maintains its effect without affecting flavor and properties.
