DISTILAZYME GA is a selected gluco amylase enzyme capable of hydrolyzing glucosidic linkages of short chain dextrins to fermentable sugars to be up-taken by the yeast during the fermentation process. DISTILAZYME GA is used in food industry for saccharification, and for simultaneous saccharification and fermentation (sSF) of whole grain mashes and starch substrates to fermentable sugars. In the SSF process, DISTILAZYME GA provides to the yeast the necessary quantity of dextrose during fermentation avoiding the stress due to high level of sugars as well as mitigating contamination during the yeast lag phase. DISTILAZYME GA optimizes the conversion of starch to fermentable sugars and reduces the risk of residual sugars at the end of fermentation. DISTILAZYME GA contributes to the optimization of yield.
