Abstract
The stability of green tea catechins was studied in the solid phase and in aqueous solution in the course of storage, degradation rate values were determined depending on ambient conditions. The stability of catechins was investigated in the course of mechanical activation; possibility is demonstrated for obtaining a mechanocomposite consisting of plant raw material and ascorbic acid, with a higher stability.
