How much is known about the polyphenol content of tea
Not all teas have the same polyphenol content. The deeper the degree of fermentation of tea leaves, the greater the number of tea polyphenols converted into other substances, and the content of tea polyphenols will be reduced accordingly.
Green tea is not fermented, the content of tea polyphenols is quite rich, there are data show that the content of tea polyphenols in green tea is 144% higher than that of black tea of the same quality, and about 59% higher than that of oolong tea of the same quality.
In addition to the variety, the quality of the tea also affects the content of tea polyphenols. For example, when making tea leaves, the more tender the tea leaves, the better the quality. Because the young leaves grow at the top, closest to the sun, they can fully photosynthesis and will synthesize more phenolic substances.
