Refined oil is manufactured through a series of chemical and physical processes that remove impurities and improve the oil's color, flavor, and shelf life. The following is the typical process of refining oil:
1. Degumming: The oil is mixed with water to remove impurities such as phospholipids, which can cause the oil to become cloudy and spoil quickly.
2. Neutralization: The oil is mixed with an alkaline solution to neutralize free fatty acids, which can also cause the oil to spoil.
3. Bleaching: The oil is filtered through clay or other absorbent materials to remove any remaining impurities and improve its color.
4. Deodorization: The oil is subjected to high heat and vacuum to remove any remaining odor and flavor.
5. Winterization: The oil is cooled and filtered to remove any waxes or solid fats that can cause the oil to become cloudy at low temperatures.
Refined oil is considered harmful to health because it often contains chemical residues from the refining process, as well as high levels of omega-6 fatty acids, which can contribute to inflammation and other health problems. Additionally, refining oil can also cause the oil to lose its natural nutrients, antioxidants, and other beneficial compounds, making it a less nutritious option compared to cold-pressed oil.
