Description of the Related Art Conventionally, green tea beverages have usually been prepared, filled, and sterilized by adjusting the particle size and turbidity of a green tea extract obtained by a kneader method or the like in a solid-liquid separation process such as centrifugation or filtration. Manufacturing. In this case, when trying to produce a refreshingly flavored green tea beverage, the strength of solid-liquid separation can be increased and the turbidity can be reduced, while the green tea particles are included, and the flavor is rich and deep. In the case of manufacturing the green tea beverage of (1), the strength of solid-liquid separation can be reduced and the turbidity can be increased.

その製品に関する。DISCLOSURE OF THE INVENTION The present invention relates to a method for producing green tea and a product thereof in which a conventional solid-liquid separator is used in the production process of green tea and the turbidity of green tea can be freely adjusted. .
【０００６】[0006]
【課題を解決するための手段】本発明の第一は、緑茶抽
出に伴って生じる微粒子を本質的に含まない透明緑茶抽
出液に、緑茶粉末を添加して濁度をＯＤ720で０．０５
〜３．００としたことを特徴とする緑茶飲料に関する。The first aspect of the present invention is to add a green tea powder to a transparent green tea extract liquid that essentially does not contain fine particles generated by green tea extraction, so that the turbidity is 0.05 at OD 720 .
It is related with the green tea drink characterized by being set to -3.00.

する緑茶飲料の製造法に関する。The second aspect of the present invention is characterized in that the fine particles are removed from the green tea extract by centrifugation, and green tea powder is added at the time of preparation to adjust the turbidity to an OD 720 of 0.05 to 3.00. The present invention relates to a method for producing a green tea beverage.
【０００８】緑茶抽出液から微粒子を除去する方法とし

離可能な最小粒径が０．５〜５μｍの条件で利用するの
が好ましい。As a method for removing fine particles from the green tea extract, a centrifuge is used. Centrifugation is preferably used under the condition that the minimum particle size that allows 100% separation is 0.5 to 5 μm.

０．１〜１５０μｍの緑茶粉末がより有効である。The green tea powder to be added at the time of preparation may be any one as long as green tea is finely crushed, but it is obtained by crushing tea leaves with a cutter rotating at a high speed rather than the green tea powder obtained by the method of producing matcha. The green tea powder is preferable because it has a uniform particle size. The particle size of the green tea powder may be arbitrarily adjusted with a separator, but a green tea powder having a particle size distribution of 0.1 to 150 μm is more effective.

５〜１．５が好ましいとの知見を得た。According to the production method of the present invention, the green tea beverage can be adjusted to have an appropriate turbidity. Turbidity affects the texture of green tea. That is, if the turbidity is too large, the graininess increases and the miscellaneous taste increases. On the other hand, if the turbidity is too low, it will be too refreshing and the umami taste will be reduced. Therefore, when the green tea powder was added after centrifugation, the texture was preferable, and the turbidity at which precipitation did not occur was examined. As a result, an OD 720 value of 0.05 to 3.00, particularly 0.0
It was found that 5 to 1.5 is preferable.
