Tea Chemistry

Abstract

Abstract The chemistry of tea as a beverage is reviewed in depth, covering both historical and current chemical perspectives. Special attention is given to the polyphenols in tea, although the general composition and properties are also treated. Current trends in tea science, particularly in the area of polyphenol complexation and antioxidant properties, are also covered. The need for a chemically based understanding, rather than one hypothesized from generalized and indirect observation, is stressed.
