  • Process for producing low De starch hydrolysates by nanofiltration fractionation, products obtained thereby, and use of such products
    Patent number: 6068705
    Abstract: A process for producing a low DE starch hydrolysate, involves fractionating a starch hydrolysate comprising a DE greater than about 18 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 comprising a DE of less than about 25. A process for producing a low DE starch hydrolysate blend involves combining the product produced by the process of the present invention with At least one other substance in a predetermined blending ratio to result in a low DE starch hydrolysate blend. A process for hydrogenating a low DE starch hydrolysate produced by the process of the present invention to result in an hydrogenated low DE starch hydrolysate. A process for producing a substantially thermal and shelf-life stable emulsion comprising forming a mixture of the low DE starch hydrolysate of the invention with an effective concentration of at least one ingredient to result in an emulsion.

  • Process for producing low de starch hydrolysates by nanofiltration fractionation and blending of resultant products, preferably in liquid form, with other carbohydrates
    Patent number: 5853487
    Abstract: 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.
