Consumption of oat-based food is rapidly increasing due to consumer preference for functional foods. Until now, breeding is focused on the development of naked oat for food in Korea. Hulled oats recognized as forage have strong merits for yield and stability in cultivation except milling properties. Lately, advanced milling technology provides an opportunity to use hulled oats for food. Therefore, the processing characteristics of hulled oats are of great importance for food use. This study examined the physicochemical properties and dietary fiber of 9 Korean oat cultivars (4 hulled oats as compared with 5 naked oat cultivars). Findings showed that the color values (i.e. L and W) of hulled oat cultivars in seed and flours are lighter than the naked oats. The protein and ash contents are higher in hulled oats as compared with naked oats. The unsaturated fatty acid (USFA), mainly C18:1, C18:2 were 80~83%. USFA of ‘Daeyang’ (DY, naked) and ‘Jopung’ (JP, hulled) were 82.0 and 81.9% respectively. Total Dietary fiber and Total β-Glucan contents ranged from 13.2 to 20.6% and from 3.4 to 4.1% in oat flours. The ‘DY’ (4.10%, naked), ‘JP’(4.09%, hulled) and Highspeed (4.07%, hulled) showed high levels of β-Glucan contents. Findings of the study will provide useful information in extending the use of hulled oats for food.
