Summary Green tea catechins are efficient absorbers of reactive oxygen species in vitro and can also act as in vivo antioxidants . However, low bioavailability and degradation of catechins during storage and digestion are the key limitations for their use, thus being a hindrance for getting the maximum benefit for one's health. To a certain extent, this problem can be solved using encapsulation. This paper focuses on stability of maltodextrin‐encapsulated green tea catechins subjected to thermal treatment in air. A positive effect of encapsulation on the stability of green tea catechins during thermal treatment was shown. Catechi stabilisation is shown to occur due to catechin–polysaccharide interaction; diffusion hindrance has almost no effect on stability of the resulting particles.
