  The present invention has been made in view of the problems of the prior art, and has a very excellent antibacterial effect and freshness-keeping effect by volatilizing and processing, and is a volatilization composed of highly safe naturally derived components. Providing sexual materials.

  In order to solve the above-mentioned problems, the present inventors have intensively searched for those having a strong antibacterial effect and a freshness maintaining effect by isolating volatile components of various natural products. As a result, the present inventors have found that capilin contained in pearl millet and the like has extremely high antifungal properties even when volatilized, and exhibits an excellent freshness-keeping effect. That is, the present invention is a volatile material having antibacterial properties and freshness retention, characterized by containing an extract of Kawara mugwort, particularly capilin. The present invention also relates to foods, fruits and vegetables treated with volatile materials having antibacterial properties and freshness preservation.

  By volatilizing the capillin contained in the extract of Kawaramugi, it has excellent antibacterial properties against foods, fruits, plants, and other causative bacteria such as mold, and also exhibits a freshness-keeping effect. Thus, it is possible to provide a volatile material that is extremely safe using natural components. Furthermore, by treating with the volatile material having antibacterial properties and freshness preservation of the present invention, it is possible to suppress the occurrence of spoilage and provide foods, fruits and plants with good freshness and high safety over a long period of time. .

  The present invention is described in detail below.

The capilin used in the present invention is a capilin-containing extract extracted from Artemisia capillaris chumb. The extract obtained from Kawara mugwort is registered as an existing food additive under the name of Kawara mugwort extract and is a highly safe raw material. Since capilin is abundantly contained in flower ears, it is preferable to use dried flower ears.

  Capillin is mainly obtained by immersing the ears of pearl millet in an extraction solvent. Examples of the extraction solvent include lower alcohols such as methanol, ethanol and isopropyl alcohol, polyhydric alcohols such as glycerin, propylene glycol and 1,3-butylene glycol. , Organic solvents such as ketones such as acetone and methyl ethyl ketone, ethers such as methyl ether and diethyl ether, hydrocarbons such as hexane and cyclohexane, oils and fats such as vegetable oils and animal oils, and water good. Capillin extracted with these extraction solvents may be used as it is, but since the active ingredient content is low and it may be necessary to add a large amount, the solvent should be completely distilled off or concentrated appropriately. May be used. At that time, in order to prevent the components from distilling with the solvent, polyhydric alcohol such as glycerin, 1,3-butylene glycol, propylene glycol, glycerin fatty acid ester, polyglycerin fatty acid ester, sucrose fatty acid ester, etc. are added. And may be concentrated. Moreover, you may use the essential oil component obtained by steam distillation from Kawara mugwort as it is. Furthermore, you may use the extract extracted using well-known methods, such as a supercritical fluid. Further, capillin may be separated and used from a solvent extract or an essential oil component obtained by steam distillation by column chromatography, high performance liquid chromatography or the like. In addition, synthesized capilin may be used.

  The capilin content of the volatile material having antibacterial properties and freshness preservation of the present invention is not particularly limited.

  You may mix carriers, such as a cyclodextrin, a silica gel, and a zeolite, with the volatile material provided with the antibacterial property and freshness maintenance of this invention. Thereby, it is possible to control the volatility of capillin and to provide sustained release.
