Document Type and Number:
Japanese Patent JPH0157682
Kind Code:
B2
Abstract:
A mixture of starch, for example corn starch, with a reagent which reacts chemically therewith, for example an etherification esterification or oxidation reagent, is subjected to UHF radiation, e.g. at 2450 MHz, to effect chemical modification of the starch, the mixture having a moisture content greater than 10% by weight. Treatment is generally limited so that the temperature does not rise above 100 DEG C. If granular starch is used, conditions are chosen so as to effect the chemical modification without gelatinising the starch.
