    Abstract: The invention relates to a method for the modification of starch in such a way that it is suitable for surface sizing at high dry matter contents of > 15%, typically > 20%, even more than 25%. The modification of starch comprises at least degradation and stabilisation of the starch, whereby the degradation of starch is carried out by means of a chemical treatment, such as hypochlorite oxidation or acid treatment, to such a degree of degradation at which the viscosity of the surface size prepared from the starch, calculated to a dry matter content of 10% and to a temperature of 60 DEG C, still is at > 10 mPas, typically > 20 mPas, most typically > 25 mPas, Brookfield RVTD II 100 rpm. The invention also relates to a starch intended for use in surface sizing at a high dry matter content and its use in surface sizing.

    Abstract: The invention pertains to a process for the regeneration and recovery of periodate from a spent iodate solution, by reacting the iodate with at least an equimolar amount of peroxosulphate. The regenerated periodate is especially suitable for oxidising carbohydrates to dialdehyde carbohydrates. The oxidation and regeneration can also be carried out in a single stage using a catalytic amount of periodate only.

    Abstract: The invention provides a process of producing a superabsorbent polysaccharide derivative by oxidation of a alpha -glucan, glucomannan or galactomannan to introduce aldehyde functions, the oxidised poly-saccharide subsequently being reacted with sulphur dioxide or an equivalent thereof to produce a hydroxysulphonated polysaccharide. The polysaccharide may be crosslinked before or after the oxidation. The preferred polysaccharide is starch or guar.
