An improved dry grind system and method for producing a sugar stream from grains or similar carbohydrate sources and/or residues, such as for biofuel production, using membrane filtration. In particular, a sugar/carbohydrate stream, which includes a desired Dextrose Equivalent (DE) where DE describes the degree of conversion of starch to dextrose (aka glucose) and/or has had removed therefrom an undesirable amount of unfermentable components, can be produced after saccharification and prior to fermentation (or other sugar conversion process) using membrane filtration, with such sugar stream being available for biofuel production, e.g., alcohol production, or other processes. In addition, the systems and methods also can involve the removal of certain grain components, e.g., corn kernel components, including protein, oil and/or fiber, prior to fermentation or other conversion systems. In other words, sugar stream production and/or grain component separation occurs on the front end of the system and method.

A method and composition comprising hydrolyzed starch. In a first aspect, the method comprises several steps. A first step comprises combining at least a portion of pulse and a suitable enzyme to form an enzyme-pulse starting mixture. The enzyme-pulse starting mixture comprises starch. A second step comprises heating the enzyme-pulse starting mixture to between about 48.89 C. and about 93.33 C. to begin to hydrolyze the starch, thereby providing a heated pulse mixture. A third step comprises extruding the heated pulse mixture to continue hydrolyzing the starch and further to gelatinize and cook the heated pulse mixture thereby providing a pulse product comprising gelatinized, hydrolyzed starch. In a second aspect, the invention provides a composition comprising at least a portion of pulse, and the at least a portion of pulse comprises gelatinized, hydrolyzed starch.
