Abstract
This invention relates to a method of producing a starch with unique functionality in plants through mutableness, and/or using biotechnology, and/or breeding practices. Further the invention relates to the starch from maize plants and/or other plants which produce starch storing organs which contain low amylose starch which has an amylose content between 1.5% and 15% and preferably between 1.5% and 10% and most preferably 1.5 and 8%. The invention includes starch extracted from such grain due to at least one mutation induced by ethyl methanesulfonate. Additionally, the invention uses a biotechnology approach involving controlling the activity of the granule bound starch synthase enzyme in starch storing organ. The invention includes the use of the starch for its cooking, paste, and gel properties.
