Glucoamylase PUREMEI GDS

Product Description

Description
PUREMEI GDS is a food-grade glucoamylase produced from classical strains of Aspergillus niger through submerged fermentation, extraction and refining processes. PUREMEI GDS has a high conversion rate from starchy substrates into fermentable sugars. It can hydrolyze α-D-1, 4 glucosidic bonds from the non-reducing end of starches one after another. It can also slowly hydrolyze the α-D-1, 6 glucoside branch bonds of starch and cleave the α-1, 3 bonds to release glucose.
PUREMEI GDS is a powder enzyme specially designed for saccharification in baking.

Application and Benefits
Use of PUREMEI GDS gives the following benefits for baking:
  1. Non-genetic modified strains to ensure safety
  2. Increases glucose content in flours, offers sufficient nutrients for yeast fermentation
  3. Enhances dough fermentation ability to produce biogas, magnify loaf volume
  4. Increases content of glucose in flours, which is conducive to Maillard reaction, thus improves the skin color and flavors of breads
  5. Can be used in frozen dough and enable yeasts to work fast in frozen dough
 
Packaging, Storage & Shelf-Life
  • Standard packaging is 20kg cardboard drums lined with food-grade plastic bags or 20kg kraft paper bags. Customized packaging is available upon request.
  • Typical shelf-life is twenty-four months at 0∼25°C in its original packaging, sealed and unopened, protected from direct sunlight. 
  • Keep at clean, cool and dry storage room. Prolonged storage and/or adverse conditions such as humidity and 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.
