Specifications and Other Information of Our Tannase CAS 9025-71-2

Description

Tannase, also known as ellagitase, is a tannin acyl hydrolase that is prepared by submerged fermentation and refined as a highly e他ctive biological preparation. The enzyme hydrolyses the ester and carboxyl bonds of gallic acid tannins and is widely used in the tea processing and extraction industry and in the juice industry.

Effectiveness

Degrades ester-type catechins, promotes the conversion of tea cheese and prevents cold turbidity of tea beverages. Can improve the taste of tea broth, reduce bitterness and astringency, maintain colour and improve the extraction rate of tea leaves. Use in juice processing can degrade tannic acid, remove astringency and improve the taste of juice, while improving product stability.

Properties

Temperature of action: optimum 30℃-40℃, effective 30℃-60℃. pH: optimum pH 4.0-6.0, effective pH 3.0-7.0

Features

Safe: natural fermented sou陀e, high safety.
High efficiency: soluble in water, high activity, specificity and effectiveness.
