HIGH SOLUBLE FIBER BARLEY FRACTION AND DRY MILLING METHOD OF PREPARATION

摘要

Disclosed are barley flour fractions havingconcentrated levels of soluble dietary fiber ("SDF"). Thebarley flour fractions have SDF contents ranging from about18% to 30%. Also disclosed are dry milling concentrationmethods for making the high soluble dietary fiber contentbarley flour fractions. The milling methods involve sizereducing a barley flour, especially a 70% to 80% extractionflour, having a native SDF level to a controlled particlesize distribution to form a size reduced flour. this isaccomplished by a single pass pinmilling step followed byparticle size classification at an opening of 30-60 micronsto separate the size reduced flour into,a starchy fractionand the present barley flour fraction having a 1.2×-5×concentration of SDF compared to the native SDF level.
