Food Grade Tannase

Tannase, also known as tannin acyl hydrolase, is a hydrolytic enzyme that can hydrolyze tannic acid and other tannin - like compounds into gallic acid and glucose. It is mainly produced by microorganisms such as fungi like Aspergillus and Penicillium, and some bacteria. There is also a small amount of tannase in some plants.

Besthway food grade Tannase is developed by Besthway Technology with modern genetic engineering, microbe fermentation and advanced post-process technology. It could effectively hydrolyze tannin to gallic acid and glucose, which can be widely used in the production of gallic acid and tannin processing of tea, coffee, fruit juice, red wine, beer, and other beverages.

Product Functions

• It could degrade gallotannin, which is used to produce gallic acid or important gallates, such as propylgallate;
• It could highly hydrolyze tannins, improve the cold solubility of fruit juice, tea beverage, beer and other products and avoid turbidity when cooling after hot dissolution;
• It could break the ester bond between catechins and gallic acid, hydrolyze the bitter ester catechins, thus reduce the bitter taste;
• Small molecular weight water-soluble short chain substances which were composed of gallic acid , catechins and other forms could minimize the loss of active ingredients in tea, coffee, fruit juice, red wine and beer and other drinks and maintain the flavor.

Application Scheme

Recommended dosage: 50-100g/T

The optimum dosage is determined by experiments according to different processes and requirements.

Package and Storage

20kg/barrel

It should be stored under dry, ventilated and protected from light at 25℃, with a shelf life of 18 months from the date of production. The shelf life could be extended when refrigerated at 5℃.

Note

• After opening the barrel, it should be tightly tied to avoid moisture or contamination;
• Do not inhale. If inhaled, rinse mouth immediately with water for at least 15 minutes;
• People who are sensitive to enzyme dust should wear one-piece overalls, dust masks and gloves when operating. If contact with skin or eyes occurs, rinse immediately with plenty of water for at least 15 minutes.
