Beta-Glucanase GC-500

BENEFITS FOR BREWING

• Reduce wort viscosity
• Improve filtration speed and wort clarity
• Increase the colloidal stability of beer to remove chill haze caused by the β-glucan
• Degradation of β-glucan,
• Improve the efficiency of filtration in the production process of pure draft beer,
• Extend the life of the filtration membrane

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.

EFFECT OF PH & TEMPERATURE :

• Effective pH for GC-500 is from 3.5 to 6.5; the optimal pH is 4.5 to 5.5. (See Figure 1)

• Effective temperature range for GC-500 is from 30 to 65°C;
• Optimal temperature is 37 to 55°C.
• This enzyme will be completely inactivated at temperatures above 80°C for 10 minutes. (See Figure 2)
