This research has shown that plasma treatment effectively improved the cooking properties of brown rice by reducing cooking time and increasing elongation. In addition, the change in the morphological structure of the rice bran layers and the increment in the quantity of the iodine-stained area demonstrated the effectiveness of plasma treatment on the modification of brown rice. The properties of the plasma-treated brown rice were also evaluated. It was determined that the utilisation of low-pressure plasma, a novel technology in whole grain processing, not only maintained the high nutritional values of brown rice, but also provided a better textural quality and shortened the cooking time. Finally, 1 kV plasma treatment reveals the better efficiency.
