[0038] (1) Oolong tea
[0039] Oolong tea is obtained by semi-fermenting the leaves of Camellia sinensis. Just as the difference in aroma is obvious even when drinking normally, the ingredients contained in the extracts of black tea and green tea that can be distinguished by different manufacturing methods and processes also vary greatly.
[0040] Oolong tea is made by heating the tea leaves during the fermentation process to stop the fermentation and carry out semi-fermentation. The preparation of oolong tea leaves can also be carried out by any method known to those skilled in the art. Tea leaves can be prepared, for example, through processes such as drying, semi-fermentation, and rolling. In addition, the tea leaves may be pulverized before the extraction step. This drying and crushing step can be performed by methods known to those skilled in the art, and the order and number of times thereof are not particularly limited. The drying method is not particular...
