Plant oils are natural oils extracted from various parts of plants, including seeds, nuts, fruits, and leaves. Common examples include olive oil, coconut oil, and sunflower oil. These oils are often used in cooking, cosmetics, and as dietary supplements due to their nutritional benefits and flavor-enhancing properties. The extraction process typically involves pressing or solvent extraction to obtain the oil. Plant oils are rich in fatty acids, vitamins, and antioxidants, making them valuable for health and wellness. They can also serve as a source of energy and are often used in biodiesel production as a renewable energy source.
