GELLED STARCH COMPOSITIONS AND METHODS OF MAKING GELLED STARCH COMPOSITIONS

摘要

A starch composition is made by combining starch with a species which induces gelation, and cooking the starch before or after the combination, to produce a gel. The species which induces gelation is selected from the group consisting of the following species and combinations thereof. (a) one or more anionic, cationic or amphoteric inorganic colloidal species; (b) one or more species capable of ionic or coordination bonding; and (c) one or more species capable of hydrogen bonding. The invention also provides a dry starch composition suitable for forming an additive for a paper furnish. A method of making a starch composition is also provided.
