Product Description

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. 

Product Characteristics
Declared Enzyme:       Beta-Glucanase
Systematic Name: EC 3.2.1.6, 1,3(or 4)-beta-D-glucan 3(4)-glucanohydrolase
Appearance: Yellow brown liquid
Activity: 50,000 U/ml (minimum)


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

Effect of Temperature 
The effective temperature range for GC-500 is from 30 to 65°C; the optimal temperature is 37 to 55°C. This enzyme will be completely inactivated at temperatures above 80°C for 10 minutes. See Figure 2.
                                     
 
Applications
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
 
Dosage Guidelines
The optimal dosage of GC-500 should be determined according to the actual situation. Typical  dosage in beer brewery is 10 to 50 grams per ton of malt wort. 
 
Packaging, Storage & Shelf-life 
  • GC-500 is packaged in 25kg, 30kg HDPE plastic drums or 1125kg IBC totes. Customized  packaging is available upon request. 
  • Typical shelf-life is six months if it is stored below 25°C in its original packaging, sealed and  unopened, protected from the sunlight.  
  • Its shelf-life will be eighteen months if this product is stored properly at 0∼10°C.  
  • This enzyme has been formulated for optimal stability. Prolonged storage and/or adverse  conditions such as higher temperatures may lead to a higher dosage requirement. 
 
Safe Handling of Enzymes
Inhalation of enzyme dust and mists should be avoided. In case of contact with skin or eyes,  promptly rinse with water for at least 15 minutes. For detailed handling information, please refer  to the Safety Data Sheet.
