Product Description

Glucoamylase GA-6000FG is a food grade powder preparation made from selected strains of Aspergillus niger using submerged fermentation, extraction and refining techniques. GA-6000FG has a high conversion rate of starchy substrates into fermentable sugars. It can hydrolyze α-D-1, 4 glucosidic bonds from the non-reducing end of starch one after. It can also hydrolyze the
α-D-1, 6 glucoside branch bonds of starch and cleaves the α-1, 3 bonds, releasing glucose. GA-6000FG is widely used in the industries such as alcohol, distilled spirit, brewage, etc.
Product Characteristics
Declared Enzyme:      
Systematic Name:
EC, 1,4-alpha-D-glucan glucohydrolase
Light yellow powder
600,000 U/g (minimum)
8% (maximum)
Effect of pH
Effective pH range for GA-6000FG is 3.0 to 5.5. For maximum activity, the optimal pH is from 3.5 to 4.5. See Figure 1.
Effect of Temperature 
Generally, the temperature range for GA-6000FG is 30 to 65℃. The optimal temperature range is 55 to 60°C. See Figure 2.
Applications and Benefits
GA-6000FG is used to saccharify liquified mash from various sources including corn, milo, barley, wheat, rice, potatoes and tapioca. The resultant glucose product is fermented by yeast or another appropriate microorganism to yield alcohol.
GA-6000FG is designed to ensure the following benefits:
Increased fermentation rate
Increased alcohol yields
Efficient starch/dextrin degradation
Less residual starch in distiller’s grains
Improved performance in pre-saccharification processes
For ground-grain processing plants using simultaneous saccharification fermentation (SSF),
GA-6000FG may be added directly to the fermenter. For ground-grain dry mill plants and for wet mill plants using a separate pre-saccharification step prior to fermentation, GA-6000FG may be added to the cooling mash or liquefied starch when the temperature reaches 55 to 60°C. Temperatures above 65°C can result in loss of activity.
GA-6000FG should be dissolved in 25~30℃ warm water at a recommended ratio of 1:10 (enzyme: water) prior to use it.
Dosage Guidelines
GA-6000FG is generally added at a level of 0.18 to 0.23kg/TDS. The actual enzyme requirement is dependent on the raw materials, temperature, reaction time, and pH of the individual plant saccharification/fermentation process, and its desired result.
GA-6000FG is packaged in 25kg cardboard drums or kraft paper bags. Customized packaging is available upon request.
Storage & Shelf-life 
  • This enzyme has been formulated for optimal stability.
  • Typical shelf-life is twenty-four months provided it is stored below 25°C in its original packaging, sealed and unopened, protected from the sunlight.
  • 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 the skin or eyes, promptly rinse with water for at least 15 minutes. For detailed handling information, please refer to the Material Safety Data Sheet.
