Abstract

Flour from three varieties of rice containing high, medium and low amounts of amylose-equivalent (AE) was extracted with water at 96 °C. Gel permeation chromatography (GPC) of both the soluble and insoluble components of the rice flour on Sepharose CL-2B gave two fractions (FR I and FR II), as reported for native starch. Nearly one-third of the insoluble matter belonged to FR II and an equal proportion of soluble matter was FR I. The earlier assumed equivalences FR I of native starch ≈ insoluble AE of rice flour amylopectin and FR II of starch ≈ soluble AE of flour amylose, would no longer be valid.
