Q. What is instant tea powder?

Instant tea powder concentrate is extracted from tea wastes processed leaves or concentrated under low pressure undried fermented leaves and then freeze-dried spray-dried or vacuum-dried to produce instant tea powder. The fermented tea is made by picking the leaves letting them wither until around two-thirds of their original water content has evaporated and then rolling them to break down their cell walls. The amino acids in the crushed leaves then undergo a chemical reaction known as fermentation. During fermentation molecules known as catechins undergo changes that result in antioxidants that are good for the human body.
