Description

Tannase (Tannin Acyl Hydrolase, EC 3.1.1.20) is a hydrolytic enzyme that catalyzes the breakdown of tannic acid and other hydrolysable tannins into gallic acid and glucose. This enzymatic action is critical for improving clarity, reducing astringency, and enhancing the bioavailability of compounds in various industrial processes. It is an essential biocatalyst for manufacturers in the food & beverage, nutraceutical, and leather processing industries seeking natural and efficient solutions.

Application

• Beverage Processing: Used to prevent haze formation and reduce astringency in fruit juices, iced tea, wine, and beer by degrading tannins.
• Gallic Acid Production: Serves as a key biocatalyst for the enzymatic hydrolysis of tannic acid to produce high-purity gallic acid, a valuable pharmaceutical and antioxidant intermediate.
• Animal Feed Additive: Incorporated into feed to hydrolyze anti-nutritional tannins in ingredients like sorghum, improving protein digestibility and animal growth performance.
• Leather Manufacturing: Applied in the dehairing and bating stages of leather processing to degrade tannins and soften hides.
• Nutraceutical & Functional Foods: Enhances the bioavailability of beneficial polyphenols in plant-based extracts and green tea by breaking down complex tannins.
• Wastewater Treatment: Employed in bioremediation processes to degrade tannin-rich effluents from industries like tanneries and coffee processing.
