A process for producing a substantially non-retrograding starch hydrolysate, involves fractionating a starch hydrolysate comprising a DE greater than about 21 using a nanofiltration membrane, having a molecular weight cut-off of less than about 4,000 daltons, under nanofiltration conditions effective to result in a low DE starch hydrolysate fraction comprising a DE of less than about 25. A process for producing a substantially non-retrograding, low DE starch hydrolysate blend involves combining the product produced by the process of the present invention with a carbohydrate in a predetermined blending ratio to result in a low DE starch hydrolysate blend. A process for hydrogenating a low DE starch hydrolysate fraction produced by the process of the present invention to result in an hydrogenated low DE starch hydrolysate fraction.
A process for producing a substantially non-retrograding starch hydrolysate, said process comprising fractionating a starch hydrolysate comprising a DE greater than about 21 using a nanofiltration membrane selected from the group consisting of teflon membranes, stainless steel membranes, ceramic membranes, polyamide membranes, and polysulfonated polysulfone membranes having a molecular weight cut-off of less than about 4,000 daltons under nanofiltration conditions effective to result in a low DE starch hydrolysate fraction comprising a DE of less than about 25.
A substantially non-retrograding, low DE starch hydrolysate product comprising a low DE starch hydrolysate having a DE within a range of about 4 to about 20 and having less than about 10% weight concentration of mono- and di-saccharides and less than about 20% weight concentration of oligosaccharides with degree of polymerization higher than about 21.
