儿茶素改性的研究进展

摘要/Abstract

摘要： 儿茶素是茶叶中的主要活性物质，但由于较低的溶解性、稳定性及生物利用率使其在食品、医药、化工等领域的应用受到限制，因此通过改性可以提高儿茶素的应用特性。综述儿茶素改性的主要物理、生化方法以及改性后儿茶素的理化性质和生物活性，并展望儿茶素改性的发展方向。

关键词: 儿茶素, 改性, 理化性质, 生物活性

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.

Key words: catechins, modification, physico-chemical properties, bioactivity
