Method of dry milling and preparing high soluble fiber barley fraction

摘要

Disclosed are barley flour fractions having concentrated levels of soluble dietary fiber ("SDF"). The barley flour fractions have SDF contents ranging from about 18% to 30%. Also disclosed are dry milling concentration methods for making the high soluble dietary fiber content barley flour fractions. The milling methods involve size reducing a barley flour, especially a 70% to 80% extraction flour, having a native SDF level to a controlled particle size distribution to form a size reduced flour. This is accomplished by a single pass pinmilling step followed by particle size classification at an opening of 30-60 microns to separate the size reduced flour into a starchy fraction and the present barley flour fraction having a 1.2X-5X concentration of SDF compared to the native SDF level.
