Theabrownin: An Important Component In Tea
Feb 07, 2025
What is Theabrownin?
Theabrownin is a polyphenolic compound polymerized from compounds such as catechin and gallocatechin. Its molecular weight is large, its structure is complex, and it is generally not easily absorbed by the human body.
But it can contact intestinal bacteria, regulate the structure of intestinal flora, and maintain the homeostasis of intestinal flora. Mainly found in partially fermented oolong tea and fully fermented black tea and dark tea.
The preparation methods of theabrownin include solvent extraction, ion exchange, adsorption, etc. Among them, solvent extraction is one of the most commonly used methods. This method uses ethanol as the solvent and obtains theabrownin through extraction, separation, concentration and other steps.
theabrownin benefits:
1. Antioxidant
Theabrownin can effectively scavenge free radicals, protect cells from oxidative damage, and play a certain role in preventing cardiovascular disease, cancer and other diseases.
2. Affects the aroma of tea leaves
Theabrownin can affect the aroma and taste of tea. During tea processing, theabrownin powder interacts with amino acids, sugars and other substances to produce different aromas and flavors.

3. Affect the color and taste of tea leaves
Theabrownin can affect the color and taste of tea. As the temperature and humidity change during tea processing, the content of theabrownin will also change, thus affecting the color and taste of tea.
4. Affects the brewing resistance of tea leaves
The brewing resistance of tea is related to the content of its contained substances, and TB theabrownin is one of them. During tea processing, if the content of theabrownin is too high or too low, it will affect the tea's brewing resistance.
5. Anti-aging
Theabrownin is a water-soluble polyphenol substance mainly extracted from black tea Pu'er tea. It can improve immunity, regulate blood pressure and blood lipids, reduce blood viscosity, increase cell activity and delay aging.
