A batch fermentation process ferments a starch hydrolysate containing 80-98 weight percent of glucose based on total carbohydrate and 0.3-5% weight percent of isomaltose based on total carbohydrate to a fermentation product. A fermentation broth is formed containing a first portion of a total amount of the starch hydrolysate so that the fermentation broth has an initial glucose concentration of at least about 50 g/L. Fermentaion is carried out until the fermentation broth contains 30 g/L or less of glucose. An effective amount of at least one active enzyme that converts isomaltose into glucose is adding to the fermentation broth. Then the remaining portion of the total amount of starch hydrolysate is fed into the fermentation broth to maintain a glucose concentration of from about 5 to about 15 g/L in the fermentation broth throughout the feeding step. The final fermentation broth containing the fermentation product is then produced.

The present disclosure provides a method for continuously producing starch saccharification products by using high-concentration starch milk.

In a first aspect of the present invention, there is provided a fermentation process for fermenting a carbon source comprising glucose and one or more oligosaccharides in the presence of a microorganism capable of fermenting glucose into a fermentation product, said process comprising the steps of: (a) forming an initial fermentation broth comprising the carbon source and the microorganism; (b) fermenting the broth under conditions suitable to ferment the glucose; (c) adding to the broth an effective amount of at least one active enzyme capable of depolymerizing the one or more oligosaccharides; and (d) recovering the fermentation product; wherein the carbon source comprises dextrose greens.

The present invention relates to a method for increasing attenuation in a fermented beverage. More particularly, the method relates to addition of a transglucosidase to a maltose depleted fermentate to convert non-fermentable dextrins to maltose.
