Oat is an economically important crop and ranks sixth in world cereal production after maize, wheat, rice, barley sorghum. It has been primarily utilized as livestock feed. However, the utilization of oats for human consumption increased progressively, owing to its dietary health benefits which relies mainly on total fibre ?-glucan content, significantly reduces postprandial blood glucose, insulin lipids, especially serum low density lipoprotein cholesterol. Henceforth, enhancing b-glucan...
