Food Grade High Concentration Saccharification Enzyme

Glucoamylase SUPERMEI GD in Liquid Form

Halal and Kosher Certified , Ideal for Alocol and Brewing

, 

SUPERMEI GD is a food grade high concentration Glucoamylase derived from selected strains of Aspergillus niger using submerged fermentation, extraction and refining technology. SUPERMEI GD 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.

SUPERMEI GD is suitable for saccharification in alcohol production.

Product Characteristics

SUPERMEI GD has a robust glucoamylase activity. Use of this product provides higher alcohol yields, faster fermentations, and lower residual starch levels.

Applications and Benefits

SUPERMEI GD 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.

SUPERMEI GD has been designed to ensure the following benefits for alcohol production:

• Increased fermentation rate
• Increased alcohol yields
• Efficient starch/dextrin degradation
• Less residual starch in distiller’s grains
• Improved performance in pre-saccharification processes

Effect of pH

Effective pH range for SUPERMEI GD is 3.0 to 5.5. For maximum activity, the optimal pH is from 3.5 to 4.5. 

Effect of Temperature

Generally, the temperature range for SUPERMEI GD is 30 to 65°C. The optimal temperature range is 55 to 60°C. 
 

Application Guidelines

For ground-grain processing plants using simultaneous saccharification fermentation (SSF), SUPERMEI GD 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, SUPERMEI GD 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.

Dosage Recommendation

SUPERMEI GD is generally added at a level of 0.35 to 0.45kg/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.

Packaging

SUPERMEI GD is packaged in 25kg, 30kg plastic drums or 1125kg IBC totes. Customized packaging is available upon request.

Storage and Shelf-life

This enzyme has been formulated for optimal stability. Typical shelf-life is six months provided 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 it 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.

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 appropriate Material Safety Data Sheet.
