  • Patent number: 8007850
    Abstract: The invention relates to a method for making a powder containing crystalline particles of glucopyranosyl-alditols, including the continuous mixing of a glucopyranosyl-alditol syrup with a dry matter content of at least 80% by weight and a glucopyranosyl-alditol content of at least 95% by weight, preferably of at least 98% by weight based on dry matter, the mixing being carried out by simultaneously dispersing the glucopyranosyl-alditol syrup and germs containing glucopyranosyl-alditols in an open rotary container containing (glucopyranosyl-alditol)-based granules, whereby the glucopyranosyl-alditol syrup and the germs containing glucopyranosyl-alditols are mixed at the surface of the (glucopyranosyl-alditol)-based granules contained in the container, recovering the (glucopyranosyl-alditol)-based granules from the container and crystallizing the glucopyranosyl-alditols contained in the granules, the (glucopyranosyl-alditol)-based granules in the container being kept in motion by rotating the container.

  • Publication number: 20090226590
    Abstract: The present invention relates to a granulated sweetening composition, characterized in that it comprises: a poorly soluble polyol with a water solubility of less than 60 g/100 g of solution at 20° C., a hydrogenated dextrin with a molecular weight between 3000 and 5000 daltons, maltitol. The invention is also directed towards a process for preparing such a composition.

  • 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.

  • 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.
