Solution Features
Waxes in edible oils are high molecular esters formed by the combination of monounsaturated fatty acids and monohydric alcohols. They have a high melting point, poor solubility, and are not absorbed by the human body. When the oil temperature drops, these waxes can crystallize, causing the oil to become cloudy and affecting the product's appearance.

Corn crude oil contains approximately 500 mg/kg of wax. Conventional refining cannot remove waxes from edible oils. To remove waxes, the oil must go through a process of cooling, crystallization, wax precipitation, and filtration. Therefore, a dewaxing section needs to be added to the conventional processing flow when processing these three types of oils.

Filtration
Cooling and crystallization
The dewaxing section is an additional step in the conventional refining process, added either after drying or after decolorization. It not only removes waxes but also eliminates colloidal substances in the oil.
