Key Processes of Edible Oil Refining & International Market Certification Standards

Key Processes of Edible Oil Refining & International Market Certification Standards

With the continuous regulation of the global edible oil market, requirements for oil quality, food safety and market access have been constantly raised in various countries. A set of refining equipment in line with international standards is not only the foundation for oil mills to ensure oil quality, but also the key to smooth export, customs clearance and sales.

Core Functions of Edible Oil Refining

Crude oil contains impurities such as gums, free fatty acids, pigments, and unpleasant odors, which cannot directly meet edible and export standards.

Refining effectively:

• Removes impurities and improves oil transparency and stability
• Reduces acid value and peroxide value to extend shelf life
• Enhances color and taste to meet Grade 1 edible oil standards
• Satisfies national food safety requirements and passes market access certifications smoothly

Main Refining Processes

1.Degumming: Removes gums such as phospholipids to prevent emulsification and deterioration

2.Deacidification: Reduces free fatty acids to prevent rancidity

3.Dehydration: Conducts vacuum drying to improve storage stability

4.Decolorization: Adsorbs pigments to make oil clear and transparent

5.Deodorization: Removes odorous substances to improve flavor and grade

The entire process is mature and stable, with low loss and easy operation, suitable for various oilseeds and small-to-medium oil mills.

Standards for Refined Oil

After complete refining, edible oil meets the international Standard for Named Vegetable Oils , with:

• Acid value ≤ 0.2
• Peroxide value ≤ 5
• Free of moisture and impurities
• No off-odors or solvent residues

This meets import customs clearance and commercial procurement requirements of most countries worldwide (including EU standards, export standards, and retail standards for large supermarkets).
