DISCLOSURE OF THE INVENTION The invention of the present application is to extract a large amount of active ingredients of microbial post-fermented tea of green hair tea by heating microbial post-fermented tea of green hair tea for a long time, an extraction method and a simple method. Moreover, it is to provide a device for safely heating for a long time and extracting more active ingredients.

[0004]

[Means for Solving the Problems] Among the six major types of tea, microbial post-fermentation tea of green hair tea, which is a type of black tea, is microbial post-fermentation of green hair tea. It is known that it has a unique component not found in teas and has a high content of anti-aging agents, anti-cancer substances and the like. The inventor of the present application, in order to obtain an extract of the effective components of microbial post-fermented tea of green hair tea, which has a unique component among teas as a beverage that is effective and safe for the human body, By heating for 1 hour or more (several days, preferably 2 to 4 hours) and extracting to decompose proteins, lipids, ash, etc. contained in microbial post-fermented tea of green hair tea, chemical reaction of components It becomes possible to extract more minerals, vitamins, amino acids and other substances, and the components of these microbial post-fermented teas of green hair tea are effectively absorbed into the body during drinking, activating cells and metabolism. It was found that it is effective for promotion, and that more substances having a food preserving action, a cooking promoting action, and a flavoring action can be extracted, and the invention of this application has been completed. By regularly drinking the active ingredient, the extract solution of the microbial post-fermented tea of green hair tea for maintaining the health, the extraction method, and for that reason, carefully at a temperature below the boiling temperature (99 ° C or less) for a long time. It relates to a safe, effective extraction device that can be heated.

The heating temperature is 50.degree. C. or higher, preferably 80.degree. C. or higher. In addition, as a heat treatment device, a device capable of heating so as not to boil at 50 to 99 ° C., particularly 80 to 99 ° C. does not boil, which is safe and preferable. By heating for a long time in this way, it is possible to change the aroma component possessed by the microbial post-fermented tea of green hair tea and extract the specific component possessed by the microbial post-fermented tea of green hair tea by decomposition or the like, Also, by using a device that heats at a temperature below the boiling temperature for a long time,
It has become possible to safely obtain the active ingredient of microbial post-fermented tea of green hair tea. In addition, the heating device of the invention of this application heats the microbial post-fermented tea of green hair tea by heating it to a temperature below the boiling temperature and extracting it for a long time so as not to boil, and in some cases, 30 minutes is basically used. As the above, heating may be performed by changing the heating time, or heating may be performed gradually. Conventionally known methods such as heat drying, freeze drying and spray drying are used to obtain a dried extract from the extract.

[0006] In addition, since heating for about the first 30 minutes evaporates some of the aroma components contained in the microbial post-fermented tea of green hair tea, if necessary, this component should be evaporated and volatilized. It is preferable because it is easy to drink. Therefore, it is preferable that the lid of the extraction device is initially opened so as to be easily volatilized and then closed. As such a lid, a structure in which the central portion is bent or a structure in which the flow of steam can be adjusted by sliding is preferable. Further, the lid may be heated in an open state.

The part of the container for containing water and microbial post-fermented tea of green hair tea in the device for extracting the active ingredient from the microbial post-fermented tea of green hair tea may be integral with the heating part, or may be a separate body. May be a single container, or an outer container for separating microbial post-fermented tea of green hair tea and water, and water is circulated and after extraction tea leaves It may be a double-structured container having an inner container having a hole for taking out only.

When the container is a double container, the outer container may be constricted so that the inner container can be easily attached, or may be formed in a protruding shape, or a rubber packing may be provided on the inner container. Etc. may be provided.

Further, it may have a structure such that the extract can be taken out by air pressure after extracting the microbial post-fermented tea of green hair tea. In this case, it is preferable to use a double container capable of removing tea leaves after extraction. Controlling the heating temperature to the boiling temperature or lower can be performed by a conventional temperature control method or device such as a thermostat.

According to the invention of the present application, tea is extracted over a long period of time, so that it is possible to extract a larger amount of the active ingredient, and moreover, it becomes possible to drink in an easy-to-drink state, and the tea is extracted. The device is set so that the heating temperature is below the boiling temperature and the tea does not spill over due to boiling, so you can extract tea for a long time with peace of mind and easily drink it on a daily basis. . Also,
Since it contains more components than those extracted so far, it has more excellent uses, food preservation action, cooking promotion action, flavoring action and the like than ever before.
