Mustard oil extracted from seasonal crops, Brassica nigra, Brassica junea and Brassica hirta, has enormous edible and non-edibleusesin India. Theoil is consumedafter extraction from mustard seeds, generallywithout anyfurther processing. High price and dark colour of the oil make it vulnerable for adulteration. But there are some distinct physical and chemical parameters like refractive index, saponification value, iodine value, colour, essential content and unsap composition, by which the purity check of mustard oil can be done. Similarly, acid value, free fatty acid content, peroxide value, panisidine value of the oil helps to determine its conformity as safe and standard edible oil. In the present study few samples of mustard oil were procured from local market and analysed them to ascertain their purity and safety parameters. The packed samples are found as un-adulterated but few samples slightly deviated from safety standards.
