Abstract
Waxy barley grain of reduced particle size is heated to inactivate natural enzymes to obtain an enzyme inactivated meal, and beta-glucans are extracted from the meal with water. Preferably, inactivation of enzymes is by heating at about 90.degree.-115.degree. C. for about 1 to 2 hours. Solids obtained by separation during extraction are treated with alpha-amylase, beta-amylase and beta-glucanase to obtain starch conversion. Barley oil, high protein concentrate and maltose syrup are recovered.
