Ultrasonic treatment can improve the quality and cooking characteristics of brown rice. By using ultrasonic waves on brown rice, researchers found that the rice cooked faster and had better texture compared to untreated rice. The treatment changed the rice's surface, making it cook more efficiently. Treated brown rice took around 24-28 minutes to cook, while untreated brown rice needed 48 minutes. This means ultrasonic treatment can make brown rice cook faster and taste better.
