ABSAC is an amyloglucosidase enzyme which is designed to produce glucose from liquefied starch in grain alcohol production. Amyloglucosidase acts on the nonreducing ends of the soluble dextrin by hydrolyzing the linear (1, 4-a-D) and branched (1, 6-a-D) glycosidic linkages to release successive glucose units. ABSAC is produced by submerged fermentation of select strain of Aspergillus sp.

The recommended dosage is for complete reaction and highest DE and DX yields. The DE can be above 98% and DX above 96%. For highest DE and DX it is always recommended to start with a liquefied starch of DE 10-13. This maximizes yield during saccharification. ABSAC is also used to produce glucose syrups with a wide range of DE, like 40-50 DE syrups etc. However, the dosage and time for reaction has to be optimized according to the plant condition and DE or DX requirement.
Enzymes are active only at specific conditions like pH and Temperature. Their activity can be ceased by varying the optimum temperature and optimum pH conditions. For ABSAC, an increase in the temperature beyond 70°C and reducing it below 40°C and simultaneously altering the pH by increasing it to over 6.0 or decreasing it below 3.0 will effectively stop the enzyme action.
ABSAC is available in 25 Kg HDPE drums
ABSAC should be stored in cool and dry environment. ABSAC is stable for 6 months under these conditions
