Claims Analysis
Total Claims: 29
Claim 1
Independent Claim
81 words
A process for preparing a hot-water dispersible • starch-surfactant product comprising the steps of: (a) combining granular starch with at least 0.25% by starch weight of a surfactant contain-, ing a fatty acid moiety and sufficient- water to provide a moisture content of from 10% to 4 0% by total weight to form a semi-moist granular starch and surfactant blend; and (b) heat-treating said blend at a temperature of from 50°C. to 120°C. to produce a heat- moisture treated starch-surfactant product.
Claim 2
Dependent Claim
81 words
A process for preparing a hot-water dispersible • starch-surfactant product comprising the steps of: (a) combining granular starch with at least 0.25% by starch weight of a surfactant contain-, ing a fatty acid moiety and sufficient- water to provide a moisture content of from 10% to 4 0% by total weight to form a semi-moist granular starch and surfactant blend; and (b) heat-treating said blend at a temperature of from 50°C. to 120°C. to produce a heat- moisture treated starch-surfactant product.
