黑茶茶褐素的研究现状及进展

黑茶是中国特有茶类,独特的渥堆工艺使黑茶的物质成分区别于其它茶类。茶褐素是黑茶加工过程中由茶多酚氧化聚合成的一类化学结构复杂的水溶性褐色色素,是参与形成黑茶茶汤品质的重要物质之一,对人体具有一定的生理调节作用。本文综述了茶褐素的形成途径、制备方法和结构特征等性质,以及茶褐素在降脂减肥、降血糖、抗氧化、抗炎抗肿瘤等方面的生理活性,并对其研究的关键问题进行了展望,以期为茶褐素的深入研究和产品开发提供参考。 

Current research status and progress of the theabrownine in dark tea

As one of unique Chinese tea, dark tea's material composition is different from other tea due to its pile fermentation.Theabrownine, a class of complicated water-soluble brown pigment by tea-polyphenol oxidative polymerization in dark tea process, which is a vital substance for dark tea quality, and possess a certain physiological regulation function to the human body.This paper mainly reviews the formation ways, preparation methods, and structural characteristics of theabrownin. In addition, the application in therapy hyperlipidemia and adiposity, hyperglycemic effect, antioxidant, anti-inflammatory, antitumor, and other physiological activities were also reviewed. In order to provide reference for further research and product development, the key problems of the research were prospected.
