Castor Oil Food Grade is a pale yellow, viscous vegetable oil derived by cold pressing the seeds of the Ricinus communis plant. Known for its high content of ricinoleic acid, it has a mild flavor and is widely used in the food, pharmaceutical, and nutraceutical industries. As a food-grade oil, it is purified to meet strict quality and safety standards. It serves both as a laxative agent and a food additive, often used in flavor carriers, coatings, and processing aids. The oil’s high stability and low moisture content also make it suitable for specialty industrial applications in food-safe environments.
