Patent ID: 8716468

Claim:
A process for preparing a randomly-bonded polysaccharide, wherein the randomly-bonded polysaccharide is produced from ingredients comprising a monosaccharide, a polyol and an acid catalyst, wherein the process is performed in a mixing kneader device having counter-acting blades, wherein said mixing kneader device is heated to a temperature of between 160° C. and 220° C. at a reduced pressure of between 50-400 hPa, wherein the process comprises the steps of a: simultaneously or consecutively feeding the ingredients into said mixing kneader device, wherein a total moisture content of the fed ingredients in the mixing kneader device is between 10 and 30 w/w %; b: kneading and mixing the fed ingredients in said mixing kneader device in order to remove water through which the fed ingredients are dehydrated to an anhydrous syrup; and c: polycondensating the anhydrous syrup by continuously kneading it in the said mixing kneader device in order to remove water until a required degree of polymerisation (DP) is obtained, wherein the DP of over 3 is equal to or higher than 80% by weight.
