The invention is directed to a method of preparing a blend comprising a polysaccharide and a water soluble or dispersible ingredient. More in particular, the invention relates to the preparation of such blend using a filter centrifuge. The method of the invention comprises a. feeding a polysaccharide slurry to a filter centrifuge via a first inlet; b. rotating the filter centrifuge at a first centrifuge speed to provide a polysaccharide cake; c. feeding a sprayable ingredient to the filter centrifuge via a second inlet; and d. spraying the sprayable ingredient onto the polysaccharide cake while rotating the filter centrifuge at a second centrifuge speed to produce a blend of the polysaccharide and the ingredient.

Preparing a blend of polysaccharide and ingredient

The starch composition comprises a cationic, cross-linked starch that is partly swollen and partly gelatinized. It has a gelatinization coefficient gT smaller than 0.7 with T the jet cooking temperature. The starch composition suitably comprises a wheat starch or a blend of a wheat starch and another starch, for instance a root or tuber starch.

Starch composition for use in paper manufacture

The present invention relates to a method of preparing a starch-based composition, characterized in that it comprises: (a) mixing a starch substrate with sodium perborate; (b) adding water to the mix of step (a) to form a slurry; and (c) pasting the slurry of step (b), provided that the method does not include, between steps (b) and (c), the step of adding an effective amount of hydrolytic enzyme to the slurry. The invention further relates to starch-based compositions prepared in accordance with said method, paper sizing and/or coating compositions comprising said starch-based compositions and paper products treated with said sizing and/or coating compositions.
