Finding Edible Oil Refinery Solutions for Different Oils

HOME > Knowledge Center > Finding Edible Oil Refinery Solutions for Different Oils

Most of the common edible oils are vegetable fats and oils, crude oils produced in the oil mill plant through pressing method, solvent extraction method and water substitution methods. The impurities in the crude oil affects the edible value and safe storage of the vegetable oil, it needs to be processed before it can be consumed in order to have a market value.

Understanding Oil Refinery Process Characteristics of Vegetable Oils

Typically, the edible oil refining process consists of the following four main steps: 

  • Degumming Process - Removing colloidal impurities, phospholipids and some proteins from the crude oil.
  • Deacidification Process- Removal of free fatty acids (FFA) by neutralization with alkali, also known as alkaline refining.
  • Decolorization/Bleaching Process - Removal of color pigments from the crude oil by adsorbents.
  • Dewaxing/Winterization Process- Freeze crystallization to precipitate waxes, separation and filtration to remove (Note: this step is required for high wax content, e.g., rice bran oil contains high wax content, about 3%-9%)
  • Deodorization Process- High temperature distillation at reduced pressure to remove odorous substances

The refining process characteristics of different kinds of edible oils have specific requirements according to their raw material characteristics and the demand of final products, and the selection of suitable refining methods can ensure the quality of refined oil and the retention of nutrients.

For example
► The acid value of crude rice bran oil is very high, generally in 8-20mg (KOH)/g, alkaline refining loss is big, in order to reduce the refinery cost, physical refining method can be used;
► Secondly, the wax content is high, need to add the de-waxing process;
► Thirdly, the color of crude rice bran oil are darker, and the de-coloring process is more complicated.

Clarifying the specific requirements of the refinery process for different edible oils is not only the basis for investors to ensure the quality and safety of refined oils and fats, but also the key to improving market competitiveness, optimizing production costs and efficiency, ensuring regulatory compliance and enhancing profitability.
