A Review the Enzymes of Tea and Their Role in Tea Making

A comprehensive review giving a bird's eye view of all the known tea enzymes is made. It is an observed fact that the enzymes play an important role in tea making. The enzymes are broadly categorized into four important groups. In light of recent work, methods of their isolation, their properties and their interactions with some of the commonly used chemicals in the tea industry, are discussed at length. Emphasis is placed on the specific role of each enzyme in relation to the quality of tea. The future lines and trends of research methodology have been evaluated in the light of previous work in the field.
