Abstract

The chapter covers all the existing literature on tannase and presents a unified picture of the state of knowledge on the topic, with suggestions for new areas of research. Tannin acyl hydrolase commonly called tannase, catalyzes the hydrolysis of ester and depside bonds in such hydrolysable tannins as tannic acid, thereby releasing glucose and gallic acid. Tannase acts only on the ester linkages present in hydrolyzable tannins, and does not act on condensed tannins. This enzyme finds widespread application in food and beverage processing. Tannase also finds extensive use in the manufacture of instant tea. It is also used as a sensitive analytical probe for determining the structure of naturally occurring gallic acid ester. Laboratory-scale studies on the production of tannase by solid-state fermentation showed several advantages over conventional submerged fermentation. Proper exploitation of this technique enables a significant reduction in the cost of enzyme production. Scale-up studies are essential to establish the feasibility of the process at an industrial scale. © 1997, Academic Press Inc.
