The goal of oil decolorization is not to remove all pigments but to improve oil color and prepare it for deodorization. This step also prevents color reversion, enhances the shelf life of the refined oil, and improves its quality and marketability.

Deacidification is a crucial step in oil refining that removes free fatty acids (FFAs), which are responsible for unpleasant odors and accelerate the hydrolysis and rancidity of neutral oils. This process improves oil quality, enhances stability, extends shelf life, and ensures health safety. It is considered one of the most economically beneficial steps in crude oil refining.

Degumming is a vital step in oil refining, using physical or chemical methods to remove gummy impurities from crude oil. This purification process primarily tar...

Dewaxing is an essential process in oil refining, enabling the removal of high-melting-point waxes from liquid oils. By utilizing advanced forced cooling methods, the wax crystallizes and separates from the oil. This is followed by filtration or centrifugal separation. Dewaxing is critical for oils like corn oil, rice bran oil, sunflower seed oil, and cottonseed oil, ensuring superior clarity and quality.

Sesame oil, extracted from sesame seeds, is a widely recognized edible oil that has gained immense popularity due to its rich aroma and health benefits. Known f...

Oil dewaxing is a critical process that removes high-melting-point waxes from liquid oils through forced cooling. This separation is achieved by crystallizing waxes and then using filtration or centrifugal separation to eliminate them. Oils such as corn oil, rice bran oil, sunflower seed oil, and cottonseed oil typically require dewaxing to improve quality and clarity.
