Vegetable oil is derived from various plant sources, including seeds, nuts, and fruits. It is a fundamental component of modern cuisine and finds widespread use in cooking, baking, and food preparation. The extraction process involves crushing the seeds or nuts to release the oil, which is then separated from the solid residue through pressing or solvent extraction methods. Common vegetable oil varieties include soybean oil, canola oil, sunflower oil, olive oil, and palm oil.
