  • Patent number: 10314915
    Abstract: Disclosed is a catechin bioavailability enhancer comprising cyclodextrin as an active ingredient. Further, disclosed is a composition comprising a catechin bioavailability enhancer comprising catechin and cyclodextrin. The composition disclosed in the present specification may improve the stability of catechin which has significantly low intestinal absorption rate, and thus may improve bioaccessibility, intestinal transport rate and bioavailability of catechin. Accordingly, the improved bioavailability may further increase the effects of catechin such as the effects of reducing weight and body fat, anti-oxidative effects and anti-aging effects. The composition disclosed in the present specification having the abovementioned characteristics can be effectively used in the fields of food or pharmacy.
