Does vegetable oil go bad?
Jump To:
Vegetable oil is most popularly used in cooking and for a variety of other purposes. Using an oil mill or a chemical solvent, this vegetable oil is extracted from various plants. Crushing the seeds or plants can also be used to extract them. Vegetable oil also includes polyunsaturated fat, which can aid in the prevention of heart disease.
