Due to increased consumption and demand for oat-related foods and processed food, this study examined physicochemical properties, antioxidant activity, and beta-glucan contents of 5 Korean naked oat cultivars. Oat seeds had long-grain appearance in all cultivars except for Seonyang. The contents of main components such as protein, starch, and crude fat were significantly different among cultivars. The total beta-glucan content was 3.78-4.60% and the soluble beta-glucan ratio was 71-83%. Fatty acid composition was C18:1, C18:2, C16:0, C18:0, and C18:3. Unsaturated fatty acid (USFA) content was 75.4-81.2%. 2,2-Diphenyl-1-picrylhydrazil (DPPH) and 2,2'-azino-bis-3-ethyl-benzo-thiaxoline-6-sulfonic acid (ABTS) radical scavenging activity were significantly different for each cultivar. Daeyang had the highest beta-glucan, USFA content, and antioxidant activity. Protein content showed a negative correlation with starch content (r = minus 0.775). Antioxidant activity was positively correlated with total phenol content (r =0.760). Ash content and flour whiteness showed a positive correlation (r =0.732).
