Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention is excellent in antibacterial effect,
And an antibacterial agent with improved taste.

[0002]

2. Description of the Related Art Although the antibacterial action of polyglycerin fatty acid esters has been well known, polyglycerin fatty acid esters could not be added in a sufficient amount to obtain an effect due to its unique taste. For the purpose of improving the taste of polyglycerin fatty acid ester, it has been studied to include a cyclodextrin or use a masking agent,
There has not yet been found any method for achieving both the improvement of taste and the antibacterial effect, such as a remarkable decrease in antibacterial properties and insufficient improvement of taste.

[0003]

An object of the present invention is to provide an antibacterial agent which can be used for a wide range of foods without affecting the original flavor of the food.

Means for Solving the Problems The present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, have found that the combined use of polyglycerin fatty acid ester and polyglycerin condensed ricinoleate does not reduce the antibacterial activity. The present inventors have found that the unique taste of polyglycerin fatty acid ester is reduced, and completed the present invention. That is, the present invention relates to an antibacterial agent characterized by containing a polyglycerin fatty acid ester and a polyglycerin condensed ricinoleate. Hereinafter, the present invention will be described in detail. The polyglycerin fatty acid ester used in the present invention is an ester of polyglycerin and a fatty acid, and the constituent fatty acid is not particularly limited. However, from the viewpoint of antibacterial activity, caprylic acid, capric acid, and lauric acid having 8 to 18 carbon atoms. It is preferably at least one selected from the group consisting of acids, myristic acid, palmitic acid, stearic acid and oleic acid. The polyglycerin of the polyglycerin fatty acid ester used in the present invention is a polymerized glycerin and is not particularly limited, but diglycerin, triglycerin, tetraglycerin, pentaglycerin,
At least one selected from the group consisting of hexaglycerin, heptaglycerin, octaglycerin, nonaglycerin, and decaglycerin is preferable. Examples of polyglycerin fatty acid esters include diglycerin monocaprylate, diglycerin monocaprate, diglycerin monolaurate, diglycerin monomyristate, diglycerin monopalmitate, diglycerin monostearate, Diglycerin monooleate, triglycerin monocaprylate, triglycerin monocaprate, triglycerin monolaurate, triglycerin monomyristate, triglycerin monopalmitate, triglycerin monostearate, triglycerin Monooleate, tetraglycerin monocaprylate, tetraglycerin monocaprate, tetraglycerate Nmonoraurin esters, tetraglycerol monomyristate, tetraglycerol monopalmitate esters, tetraglycerol monostearate, tetraglycerol monooleate,
Pentaglycerin monocaprylate, Pentaglycerin monocaprate, Pentaglycerin monolaurate, Pentaglycerin monomyristate, Pentaglycerin monopalmitate, Pentaglycerin monostearate, Pentaglycerin monooleate, Hexaglycerin Monocaprylate, hexaglycerin monocaprate, hexaglycerin monolaurate, hexaglycerin monomyristate, hexaglycerin monopalmitate, hexaglycerin monostearate, hexaglycerin monooleate, decaglycerin monocapryle Acid ester, decaglycerin monocaprate, decaglycerin mono Gaulin esters, decaglycerol monomyristate, decaglycerol monopalmitate esters, decaglycerol monostearate and decaglycerol monooleate and the like. The polyglycerol fatty acid ester used in the present invention preferably has a monoester content of 40% or more from the viewpoint of antibacterial activity. The monoester content referred to in the present invention refers to polyglycerin monofatty acid ester in polyglycerin fatty acid ester. The monoester content in the present invention can be determined by a general measuring method, and can be measured by, for example, gas chromatography, high performance liquid chromatography, thin layer chromatography and the like. The polyglycerol fatty acid ester used in the present invention may contain a diester or the like at all. The polyglycerin fatty acid ester used in the present invention may have one or more kinds of constituent fatty acids as a mixture.

[0005] The polyglycerin of the polyglycerin condensed ricinoleate used in the present invention is a polymer of glycerin, and is diglycerin, triglycerin, tetraglycerin, pentaglycerin, hexaglycerin, heptaglycerin, octaglycerin, nonaglycerin, Decaglycerin is preferred. The condensed ricinoleic acid of the polyglycerin condensed ricinoleate used in the present invention is a condensate of ricinoleic acid, and is generally a dimer, trimer, tetramer, pentamer, hexamer, or heptamer. , 8
Examples thereof include a monomer and the like. The HLB of the polyglycerin-condensed ricinoleate used in the present invention preferably has an HLB of 5 or less from the viewpoint of the taste reducing effect, and when the HLB exceeds 5, the unique taste reducing effect of the polyglycerin fatty acid ester But weak in practical use. The method of calculating HLB in the present invention is not particularly limited, but as an example, in general, the calculation formula of HLB of polyhydric alcohol type fatty acid ester (WC Griffin, J. Am.
Soc. Cosmetic Chemists, 1,3
11) HLB = 20 (1-S / A) (Formula-1) It is calculated by (S: saponification value of ester, A: acid value of fatty acid).

[0006] The method for preparing the antibacterial agent of the present invention is not particularly limited. Polyglycerin fatty acid ester and polyglycerin condensed ricinoleate show various states such as liquid, viscous liquid, and solid at room temperature depending on the type of the constituent components of the ester. A method of mixing and powdering using an excipient such as lactose, a method of dissolving and mixing in alcohol or the like, a method of emulsifying and mixing, and the like can be appropriately selected. The antibacterial agent of the present invention is used by direct addition or spraying to an object, but the components of the antibacterial agent of the present invention may be separately added and used within a range not exceeding an effective compounding ratio. It is.

The ratio of the polyglycerin-condensed ricinoleate to the polyglycerin fatty acid ester of the present invention is preferably from 0.1 to 100 parts, more preferably from 1 to 6 parts, per 100 parts of the polyglycerin fatty acid ester.
0 parts, more preferably 10 to 40 parts. When the ratio of the polyglycerin condensed ricinoleate is 0.
If the amount is less than 1 part, the effect of reducing the unique taste of the polyglycerol fatty acid ester is weak, and it is difficult to use it practically. When the ratio of the polyglycerin condensed ricinoleate exceeds 100 parts, it is economically expensive and difficult to use in practice.
