ABSTRACT:
Improved starch-metal derivatives are provided which have excellent dry flow characteristics and ready dispersability in hot or cold water. The preferred derivatives comprise granules of starch which have been expanded or preswelled and cross-linked, followed by reaction with a polyvalent metal salt, especially salts of Ca, Mg, Zn Cu and Al.
