Chinese people love drinking tea not only for its refreshing taste, but also as a healthy lifestyle habit developed over the years. But do you know what components in tea have beneficial effects on the body and mind? Today, Lao Zhu will talk to you about the treasure in tea - tea polyphenols.

1. What are tea polyphenols

Chinese name: Tea Polyphenols

Alternative name: Tea Tannin or Tea Tannin

Definition: The general term for polyphenolic substances in tea

Including: flavanols, anthocyanins, flavonoids, flavonols, phenolic acids, etc

Important content: Flavonoids (catechins), accounting for about 70% of the total tea polyphenols

Characteristics: It is one of the main components that contribute to the color, aroma, and health benefits of tea.

2. How much do you know about the content of tea polyphenols

Not all types of tea have the same content of tea polyphenols. The deeper the fermentation of tea, the more tea polyphenols are converted into other substances, and the content of tea polyphenols will correspondingly decrease.

However, green tea is not fermented and has a relatively rich content of tea polyphenols. Data shows 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 type, the quality of tea also affects the content of tea polyphenols. For example, when making tea, the younger the tea, the better the quality. Because tender leaves grow at the top, they can fully carry out photosynthesis and synthesize more phenolic substances.

CSY-SC8 developed and produced by Shenfen InstrumentTea polyphenol detectorCan quickly detect the content of tea polyphenols in tea and tea beverages. Suitable for tea product monitoring centers, tea production and processing, tea processing and trade, self inspection of tea growers, and rapid market screening by quality supervision departments, to constrain the quality of tea products.
