Glucoamylase PUREMEI GDS is made from Non-GMO strains of Aspergillus niger using submerged fermentation, extraction and refining techniques. PUREMEI GDS has a high conversion rate from starchy substrates into fermentable sugars. PUREMEI GDS can hydrolyze α-D-1, 4 glucosidic bonds from the non-reducing end of starch one after another. It can also hydrolyze the α-D-1, 6 glucoside branch bonds of starch and cleaves the α-1, 3 bonds to release glucose.
PUREMEI GDS offers the following benefits to baking industry:
Increases glucose content in flours, offers sufficient nutrients for yeast fermentation
Enhances dough fermentation and its ability of biogas production, hence enlarges loaf volume
Conducive to Maillard reaction, thus improves the skin color and flavors of bread
Can be used in frozen dough and enable yeasts to work fast in frozen dough
EFFECT OF PH
The optimal pH for PUREMEI GDS is 3.5 to 4.5 See Figure 1.
EFFECT OF TEMPERATURE
The effective temperature range for PUREMEI GDS is 30 to 65°C. The optimal temperature range is 55 to 60°C.
See Figure 2.

APPLICATION AND BENEFITS
Use of PUREMEI GDS gives the following benefits for baking :
■ Non-genetic modified strains to ensure safety
■ Increases glucose content in flours, offers sufficient nutrients for yeast fermentation
■ Enhances dough fermentation ability to produce biogas, magnify loaf volume
■ Increases content of glucose in flours, which is conducive to Maillard reaction, thus
improves the skin color and flavors of breads
■ Can be used in frozen dough and enable yeasts to work fast in frozen dough
PUREMEI GDS is packaged in 25kg water-proof kraft paper bags or cardboard drums with food
grade plastic bags inside. Customized packaging is available upon request.
STORAGE & SHELF-LIFE
PUREMEI GDS has been formulated for optimal stability. Its typical shelf-life is six months if it is
stored below 25°C in its original packaging, sealed and unopened, protected from direct sunlight.
Its shelf-life is eighteen months if it is stored properly at 0∼10°C. Prolonged storage and/or
adverse conditions such as higher temperatures may lead to a 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 skins or eyes,
promptly rinse with water for at least 15 minutes. For detailed handling information, please
refer to the Safety Data Sheet.
