Final answer:
Vegetable oils can be extracted through pressing or solvent extraction methods.
Step-by-step explanation:
Vegetable oils can be extracted through pressing or solvent extraction methods.
Vegetable oils can be extracted through two common methods:
- Pressing: This method involves crushing the oil-containing seeds or fruits to release the oil. The extracted oil is then separated from the solid residue through filtration or centrifugation. This method is commonly used for oils like olive oil or coconut oil.
- Solvent Extraction: In this method, a solvent (usually hexane) is used to dissolve the oil from the seeds or fruits. The solvent-oil mixture is then separated from the solid residue, and the solvent is evaporated to obtain the pure oil. Solvent extraction is commonly used for oils like soybean oil or canola oil.
