Zhulin Activated Carbon, as a professional activated carbon manufacturer, provides the coconut oil refining industry with high-efficiency, stable, food-grade coconut shell powder activated carbon for pigment adsorption, deodorization, and improving oil stability.
Why does coconut oil need decolorization?
Whether it's RBD (refined deodorized coconut oil) or food-grade oil, crude oil typically contains the following impurities:
• Natural pigments: such as carotenoids and polyphenols
• Free fatty acids and oxidation products (affecting flavor)
• Trace amounts of metal ions (promoting oil oxidation)
• Residual off-odor compounds
These substances cause coconut oil to darken in color, reduce transparency, and affect its final flavor and stability. Therefore, the industry commonly uses coconut shell powder and activated carbon for decolorization and deodorization.
Why Choose Coconut Shell Powder Activated Carbon?
Coconut shell powder activated carbon possesses the following natural advantages, making it the preferred choice in the oil and fat industry:
1. High microporous structure, particularly suitable for adsorbing small-molecule pigments in oils: Coconut shell activated carbon is rich in micropores, exhibiting significant adsorption effects on pigments such as carotenoids and phenols.
2. Good thermal stability, suitable for high-temperature decolorization processes: Oil decolorization is typically carried out at 90–120°C, and coconut shell powder activated carbon remains stable and does not decompose.
3. Low ash content, high purity, food-grade safety: After acid washing or refining processes, it has low ash content, preventing secondary contamination of oils.
4. Effective deodorization, improving the sensory quality of oils: It can remove trace amounts of off-odors and undesirable volatiles produced by oxidation, enhancing the aroma of RBD oils.
