Tannase

Tannase (CAS 9025-71-2), also known as tannin acylhydrolase, is an enzyme that catalyzes the hydrolysis of ester and depside bonds in hydrolyzable tannins, releasing gallic acid and glucose.

Where is Tannase used?

• Food processing and biotechnology: reduce astringency, improve clarity, enhance bioavailability of polyphenolic compounds in tannin-containing substrates
• Beverage production: clarify tea extracts and cold-brew tea concentrates, preventing haze formation when tannins interact with proteins at low temperatures
• Instant tea and ready-to-drink tea: stable, clear products without sacrificing flavor profile
• Wine and fruit juice processing: reduce excess tannin load, improving mouthfeel and product consistency
• Biotechnology: gallic acid production, a key intermediate for propyl gallate and pharmaceutical antioxidants, through controlled enzymatic hydrolysis of tannin-rich plant materials
• Technical-grade preparations serve fermentation processes.
