Brewing Enzyme Beta-Glucanase GC-500

A liquid Beta-Glucanase for beer brewing, juice processing and wine making, capable to reduce wort viscosity, speed up filtration , remove chill haze caused by β-glucan, improved wort clarity.

DESCRIPTION

Beta-Glucanase GC-500 is produced by submerged fermentation and advanced extraction process. It is endoglucanase which specifically hydrolyzes beta-1,3 and beta-1,4 glycosidic linkages of Beta-Glucan to produce oligosaccharide containing 3～5 glucose unit and glucose. It contains a certain amount of hemicellulase and can effectively break down beta-glucan in wheat and cereal endosperm cell wall. It is widely used in the beer brewing, juice processing and wine making industries.

APPLICATION BENEFITS
Use of Beta-Glucanase GC-500 can offer the following benefits to beer brewery:
1) Reduce wort viscosity
2) Improve filtration speed and wort clarity
3) Increase the colloidal stability of beer to remove chill haze caused by the β-glucan
4) Degradation of β-glucan, improve the efficiency of filtration in the production process of pure draft beer, extend the life of the filtration membrane
