Product Name:Tannase
English Name:Tannase
CAS No.:9025-71-2
Aliases:Tannin acyl hydrolase
Physical Properties:White to light yellow powder or liquid, soluble in water. Optimum pH is 4.0–7.0 and suitable temperature is 20–80°C. It specifically cleaves the ester bonds between catechol and gallic acid, hydrolyzes ester-type catechins and releases gallic acid, effectively reducing tea liquor turbidity and preventing cold haze in tea beverages.
Uses:Tannase is a specific enzyme used in tea beverage production to prevent cold haze by solubilizing tea cream and improving clarity and stability. It is also applied in instant tea preparation to improve cold-water solubility, and widely used for clarification and de-astringency treatment of beer, fruit juice, and wine.
Technical Specifications:
Appearance: light yellow to light brown powder or liquid, soluble in water.
Optimum pH: 4.0–7.0; suitable temperature: 20–80°C.
Enzyme activity: 0.5–50 units per gram of dry tea added.
Treatment effect: can reduce tea beverage turbidity from 80% to 8%, significantly improving clarity.
