Patanjali Musturd oil (Kacchi Ghani) is adultrated now. Earlier it used to be pure but now they have started mixing some other oil (palm oil looks like). Now they are claiming it is fortified oil with Vitamin A and Vitamin D to hide the adulteration. Once the oil is heated it becomes green in color. Smell of the oil is also very bad.
Never recommend any one to use Patanjali Musturd oil.
