Mustard oil (Sarson ka tel) is a vegetable oil and is obtained from seeds of the mustard plant. The oil is extracted from clean and sound mustard seeds, which belong to species namely compestris, juncea or napus varities of brassica. Large quantity of the mustard oil as traditional oil is used for edible purpose in many states of India namely J&K, Himachal Pradesh,Punjab, Haryana, Uttar Pradesh, Rajasthan, Madya Pradesh, Bihar, Chattisgarh, Jharkhand, West Bengal and some regions of Maharastra & north eastern states. Noticeably, India is the fourth largest oilseed producing country in the world, with mustard seeds playing a major part in this.
Kachchi ghani refers to cold press extraction process for taking out oil from seeds. Traditionally, oil from seeds were extracted in kohlus (wooden & now steel rollers). In this process, seeds are crushed at low temperature so that natural properties, antioxidants and essential oils are retained in the oil.
The tests were conducted to check adulteration of mustard oil with cheap oils like palm, mineral oil etc..
