Abstract
This invention provides a starch derived from a single plant source, comprising less than 10%, optionally less than 5%, amylopectin. The starch additionally comprises at least 75% amylose, optionally at least 85% amylose, measured by butanol fractionation/exclusion chromatography measurement. In another aspect of this invention, the starch is extracted in substantially pure form from a starch bearing plant having a recessive amylose extender genotype that is associated with amylose extender modifying genes. The starch bearing plant from which the starch is extracted is preferably a maize plant.
