Tea is obtained from the green leaves of the 'camellia sinensis' plant, a small tree of Asian origin. The black, green and white teas we enjoy drinking today are actually the leaves of the same plant. Only the way the leaves reach us is different. Green tea is the unfermented form of black tea. In fact, the raw materials for both are the same. But the difference emerges in the fabrication processes.
In black tea; The fermentation process ensures the formation of the desired color, astringency, brightness, odor and aroma. At the same time, due to oxidation between 21-32 degrees, the effect of epigallocatechin gallate (EGCG), which has antioxidant properties and a metabolism-accelerating effect, and many other beneficial active ingredients is also reduced.
In green tea, the enzymes that undergo the oxidation process lose their activity through heat, and thus the leaves remain green during the drying process. In white tea, the tea leaves are left to partially oxidize before being subjected to heat. Therefore, the antioxidant content of green and white tea is higher than black tea, which means it is more beneficial.
