In traditional medicine systems like Ayurveda, mustard oil is considered a heating oil, meaning it generates warmth in the body and is used for massages or to improve circulation. In biodiesel production, this “heating” classification has no effect—what matters is the oil’s chemical composition. Mustard oil’s fatty acid profile allows for effective conversion into biodiesel with good combustion properties when processed under controlled conditions using systems like the GlobeCore USB plant.
