Abstract
Waxy barley grain is processed by a series of processing steps to produce beta-glucan solids, a bran residue, a protein concentrate, barley oil and a maltose syrup in uncontaminated form. The process involves steps of mixing a meal produced from waxy barley grain with water, separating barley solids and a water extract, heating the water extract and separating coagulated protein and beta-glucan solids, mixing the barley solids with water and separating a bran fraction and crude starch, forming a dough from the crude starch and separating gluten and waxy barley starch from the dough, mixing the bran fraction with water and enzymes to carry out starch conversion and produce a liquid mixture, separating solids from the liquid mixture, extracting the solids with alcohol to produce oil and recovering maltose syrup from liquid remaining after separating the solids.
