Water-insoluble beta-(1,3)-D-glucan (lichenan) was determined in 43 samples of various cereal (oat, barley, wheat, millet) and pseudocereal (buckwheat, amaranth) cultivars using a modified procedure with fungal alpha-amylase (Fermizyme P 300). The content of water-insoluble beta-glucan depended on the cereal species and cultivar. The highest concentration was registered in covered oat cultivars (Cyril and the new breeding cultivar PS-100): 26.7-28.2 g/100 g dry matter (d.m.) followed by less traditional cereals such as millet, amaranth and buckwheat - more than 20 g/100 g d.m. A somewhat lower average content was found in wheat: 12.7-16.2 g/100 g d.m., in spelt: 8.5 g/100 g d.m., and in oat: 15.3-18.7 g/100 g d.m.
