What are the effect factors of oil color ?
In genreal, pure water is transparent while oil contains many other substainces. Thus the brighter oil color is, the purer oil is, the better oil extraction efficiency is.
1. Decolorization process remove pigments in oil to reduce pigment content in oil and force oil color to white.
2. Degumming removes gums in oil to make oil more transparent.
3. Dedorization and other oil extraction process can also help remove impurities in oil to pure oil to brighter.
However, transparent oil is unhealthy. We need oil to have some nutritional color, which is more healthy.
