Product Description

Non-GMO Glucoamylase PUREMEI PG For Ethanol Production

Glucoamylase PUREMEI PG is produced from non-genetic modified strain of Aspergillus niger

through submerged fermentation, extraction and refining processes. 

PUREMEI PG  can hydrolyze α-D-1, 4 glucosidic bonds from the non-reducing end  of starch

one after another. It can also hydrolyzes the α-D-1, 6 glucoside branch bonds  of starch

and cleaves the α-1, 3 bonds to release glucose. 

APPLICATION & BENEFITS

• Use of PUREMEI PG in the production of ethanol can result in higher ethanol yields, faster fermentations, and lower residual starch levels. It is designed to ensure the following benefits:

• Increased fermentation rate
• Efficient starch/dextrin degradation
• Improved performance in pre-saccharification processes
• Capable to saccharify liquified mash from various sources including corn, milo, barley, wheat, rice, potatoes and tapioca with maximized utilization of raw materials
• Non- genetic modified strain to ensure more safety

• For ground-grain processing plants using simultaneous saccharification fermentation (SSF), PUREMEI PG 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, PUREMEI PG 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 rapidly.

DOSAGE RECOMMENDATION

• PUREMEI PG is generally added at a level of 0.065 to 0.085% w/w (dry solids basis).
• The optimal dose depends on the actual processing conditions including raw materials, temperature, reaction time, pH and the desired results in individual ethanol plants.

EFFECT OF PH ON ACTIVITY

• The optimal pH for PUREMEI PG ranges from 4.0 to 4.5.

PACKAGING, STORAGE AND SHELF-LIFE

• PUREMEI PG is packaged in 25kg, 30kg HDPE plastic drums or 1125 kg IBC totes. Customized packaging is also 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.

• Prolonged storage and/or adverse conditions such as higher temperatures may lead to higher dosage requirement, thus should be avoided.

SAFETY & ENZYME HANDLING

• 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.
