Abstract

Tannin acyl hydrolase (E.C. 3.1.1.20) commonly referred as tannase, is a hydrolytic enzyme that catalyses the hydrolysis of ester bonds present in gallotannins, ellagitannins, complex tannins and gallic acid esters. Tannases are the important group of botechnologically relevant enzymes distributed throughout the animal, plant and microbial kingdoms. However, microbial tannases are currently receiving a great deal of attention. Tannases are extensively used in food, feed, pharmaceutical, beverage, brewing and chemical industries. Owing to its diverse area of applications, a number of patents have been appeared in the recent past. The present review pretends to present the advances and perspectives in the industrial application of tannase with special emphasis on patents.

Keywords: Tannase, tea, tannic acid, tannin, gallic acid.
