| Abstract: | Catechins are major bioactive substances in tea. However, the low solubility, poor stability and reduced bioavailability in vivo restrict their application. In this review, the current major methods for catechin modification and the physico-chemical properties and bioactivity of modified catechins are summarized. Meanwhile, future trends in the development of catechin modification are also proposed. |
