Historically, green tea has been cultivated for the first time in China and India, and has since spread to Southeast Asia such as Java, Ceylon, Myanmar, Thailand, and East Asia in Korea and Japan, mainly in Asia below 35 ° C. Has come. 1) Green tea has the scientific name Camellia sinensis L., and it is a perennial seed plant belonging to the tea tree family. It has a natural fragrance, natural color, natural taste, antibacterial action, antioxidant activity, anticancer activity, and anticancer activity. allergic reactions, blood pressure lowering action, anti-diabetic activity, diuretic and detoxification is known that the human body works and pharmacological properties, including one of the oldest symbols of food 2-5), the most widely consumed in the world. Green tea goes through a long history been used in various diseases and drug cultivation, manufacturing technology advances and 6) There is increasing interest in green tea as it is reported that green tea maintains health and suppresses the occurrence of diseases such as cancer. Green tea is composed of various ingredients and contains caffeine, tannin, chlorophyll, vitamins A, B 1 , B 2 , C, E and amino acids, proteins, fats, fiber, and inorganic components Ca, Mg, Cu, Mo , Sb, Ti and other components are variously contained. Among these components, caffeine and tannin are composed of polyphenol, an aromatic extract, which consists of cellulose, lignin, and catechin having several or more phenolic hydroxyl groups in the molecule. Among the polyphenol components contained in green tea, catechins are representative bioactive substances. 7) in particular including (-)-epicatechin (EC), (-)-epigallocatechin (EGC), (-)-epicatechin-3-gallate (ECG), (-)-epigallocatechin-3-gallate (EGCG), and the like. Most studies on polyphenols have been conducted 8-10 ) . Green tea catechins are known to possess various physiological activity such as anti-inflammatory, anti-allergic and anti-cancer as natural antioxidants 12-13).

Green tea catechin is a natural antioxidant known to have various physiological activities such as anti-inflammatory, anti-allergic and anti-cancer. Recently, tea has been used as an additive, such as food, medicine, health food, cosmetics by simply extracting functional ingredients from tea leaves as well as drinking beverages. Tea extracts for this purpose have been used for extracting dried tea by processing the green leaves of tea by thickening or steaming food process, but using hot water extract. There has been a problem that the cost increase factor such as

Therefore, in this study, we tried to prepare a new behavioral tea extract by enzymatic treatment in order to obtain high quality extract with improved extraction efficiency of green tea. The extract was confirmed that the wrinkle improvement effect is excellent and completed the present invention.

In order to achieve the above object, the present invention is the first step of adding water to the dry green tea and adding a hydrolase thereto; A second step of obtaining a fermentation product by performing an enzyme reaction while culturing and stirring the solution; A third step of heating and extracting the fermented product; It provides a manufacturing method for producing a fermented green tea extract containing a large amount of the functional component comprising the step of filtering and extracting the extract and separating the supernatant.

Experimental Example  2. Evaluation of wrinkle improvement effect using experimental animals

In order to confirm the wrinkle improvement effect of the extract sample obtained in the above example, the experiment was performed by applying the method disclosed in the literature (small pathogenesis, device evaluation of the skin effect, Korean Journal of Skin Barriers Journal, Vol. 8 No. 1)

2-1. Laboratory animals Experimental group

Experimental animals were fed 6-7 weeks old (22-28 g) female hairless mouse (Orient Bio, Tokyo, Japan) and used for 1 week in the nursery. Feed and water were supplied freely for the entire period. The nursery was kept at a temperature of 22 ± 1 o C, a relative humidity of 50 ± 5% and a lighting cycle of 12 hours. The experimental group was divided into four groups according to the cosmetic composition test examples 1, 2, 3, 4, a total of 20 animals in each group was used for the experiment.

2-2. Causes skin aging and sample application

Ultraviolet radiation dose was measured by UV-radiometer (UVB LP9021, Italy), and the mouse was placed in an ultraviolet irradiation cage, and the amount of light at 60 mJ / cm 2 was equally increased to 1 MED at 1 week intervals at 1 MED. 3 times a week, every other day for 5 weeks. After inducing photoaging for 5 weeks, cosmetics (essences) prepared by mixing the green tea extract concentrates at concentrations of 0, 0.1, and 0.5%, respectively, were applied as 200 μL once a day for 5 weeks as a sample.

2-3. Wrinkle measurement according to sample application by concentration

Five weeks after the start of the experiment, each group was lightly anesthetized with ether, and in order to objectively evaluate the degree of wrinkles, it was replicated using silicone polymer (SILFLO impression material, Flexico, England) on the back of the animal. ), The shape of the wrinkles was observed with a skin visometer (SV600, CK electronic GmbH, Germany).

As a result of the experiment, as shown in FIG. 2, the wrinkles of the dorsal template (reflica) of the experimental animal were examined by applying a sample through a skin visometer. In the essence application group containing 0.5% of green tea concentrate and the essence application group containing 1% of green tea concentrate, the lines of wrinkles were markedly thin and the depth was shallow. These results are expected that the application of green tea extract-containing cosmetics (essences) is effective in the improvement and prevention of wrinkles that are a typical sign of skin aging.

In addition, the results, the enzyme treatment concentration 1%, enzyme treatment time 18 ~ 24hr treatment was found to have a high physicochemical quality and content of functional components.

The green tea extract thus extracted was concentrated so that the solid content was 30%, and the content of the concentrate was applied to the skin of the mouse, and the wrinkle improvement effect was measured after applying 0.5 ~ 1% concentrate in the cosmetic (essence) composition. It has been shown to have an anti wrinkle effect.
