Abstract:
A process for preparing an amylose product, which comprises long-chain amylose with a degree of polymerization of more than 100 of 20 to 40 wt. % on dry substance, andshort-chain amylose with a degree of polymerization between 10 and 75 of 40 to 80 wt. % on dry substance, wherein the product has a dextrose equivalent of 5 to 10, wherein the product has a specific surface area, as determined by means of nitrogen adsorption, between 0.4 and less than 1.0 m2/g, and wherein the product forms a mattix thereby allowing programmed release of an active ingredient when the product is mixed with the active ingredient; comprising: treating an aqueous solution of starch with an &agr;-amylase and a debranching enzyme, wherein the &agr;-amylase and the debranching enzyme act on the starch simultaneously, isolating the amylose product from the aqueous solution, wherein the amylose product is in the form of flocks in the aqueous solution, and then drying the amylose product by vacuum drying.
