Glucoamylase PUREMEI PG
NON-GMO Saccarification Enzyme for Ethanol Production
(Halal and Kosher Certified)
Glucoamylase PUREMEI PG is a robust glucoamyalse produced from Non-GMO strains of Aspergillus niger through submerged fermentation, extraction and refining processes.
PUREMEI PG can hydrolyzeα-D-1, 4 glucosidic bonds from the non-reducing end of
starch one after another. It can also hydrolyze theα-D-1, 6
glucoside branch bonds of starch and cleaves the α-1, 3 bonds to
PUREMEI PG enables higher ethanol yields, faster fermentation and
less starch residues in the production of ethanol.
|Systematic Name||EC 18.104.22.168, 1,4-alpha-D-glucan glucohydrolase|
|Appearance||Sepia brown liquid|

PH AND TEMPERATURE PROFILE
The optimal pH range for PUREMEI PG is 3.5 ~4.5.
Effective temperature range for PUREMEI PG is 30 ~ 65°C
Optimal temperature range is 55 ~ 60°C
The robust glucoamylase activity of PUREMEI PG is capable to
saccharify liquified mash from various sources including :
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.
PUREMEI PG is generally added at a dosage 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
PACKAGING, STORAGE AND SHELF-LIFE
PUREMEI PG is packaged in 25kg, 30kg HDPE plastic drums or 1125 kg
Customized packaging is also available upon request.
|Storage and Shelf-life|
Typical shelf-life for PUREMEI PG 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.
