Pure refined oils and fats are colorless in liquid state and white in solid state, but why do the oils and fats we see in daily life have colors?

Because oils and fats contain different pigments of different quantities and varieties. In addition, the decolorization of oils and fats is mainly carried out in the decolorization process of oil refining equipment.

In fact, there are many decolorization methods for oil refining equipment, but at present, the most commonly used decolorization method in industrial production is adsorption decolorization. Under the corresponding conditions of decolorization process and equipment, factors such as raw oil quality, adsorbent selection and addition amount, operating pressure, decolorization temperature, and decolorization time will affect the decolorization effect. In addition, in the refining process of oil equipment, hydration degumming, alkali scouring, deodorization and other processes also have corresponding decolorization effects. Therefore, in order to improve the color of finished oil, ensure the quality of finished oil, and improve its oxidation stability.
