The refining process involves several stages to purify the oil. Degumming removes phospholipids, neutralization eliminates free fatty acids, and bleaching with activated clay improves color and clarity.
How Impurities Are Removed During Oil Refining
Samples are tested for acidity, peroxide value, and contaminants to ensure the final product meets international safety standards. Interesterification rearranges the fatty acid chains on the glycerol molecule, altering the oil's texture and stability without introducing trans fats, providing a versatile ingredient for food manufacturers.
This initial purification is critical to prevent contamination and ensure the efficiency of subsequent extraction steps. Finally, deodorization uses steam distillation to remove volatile compounds, resulting in a neutral-tasting, shelf-stable product.
