Waxy barley starch with unique self-liquefying properties

Abstract

Barley starch granules are prepared which have been found to have native amylase bound sufficiently tenaciously onto the starch granule, such that it is not extracted during ordinary separation of the starch from the grain, and hence has the property of being self-liquefying when the granules are heated to a temperature of from 67.degree. to 75.degree. C. These granules are obtained by separation from a novel variety of barley formed by cross-breeding a first barley variety characterized by a hulless gene n n on chromosome 1 and a second barley variety which is characterized by a waxy endosperm gene wx wx on chromosome 1. In one embodiment of this variety, the first variety cross-bred is characterized by both a short awn gene lk2 lk2 and a hulless gene n n on chromosome 1. In the most preferred embodiment, a variety now called Washonupana has been discovered which will yield the novel granules of this invention.
