Mustard and Canola oil are used around the world, as they can be used as substitutes for cooking in order to provide an alternative form of dietary fat and flavor. The saturated and unsaturated fats in appropriate quantity are essential for the body to function properly. Earlier, the mustard oil was considered to be allergic and toxic, due to its erucic acid contents, which results a negative impact on human body. Hence, the oil was prohibited in some countries. But today after the successful research and work; the oil is free from toxic nature and hence is fit to consume.
