Mustard seeds are high in essential oil and are great source of plant sterols such as brassicasterol, campesterol, sitosterol, avenasterol, and stigmasterol. The global mustard seeds market is expected to witness significant growth in the coming years mainly attributed to increasing application of mustard seeds in food and beverages industry, pharmaceutical industry, personal care and cosmetic industry and others.
