Oil decolorization

Subject Powdered Activated Carbon for Palm-Oil Bleaching — deeper color cut, lower clay dose, PAH & aflatoxin removal, low-ash low-iron.

Pain → Solution

• Crude palm oil carries high carotenoids and chlorophyll, so bleaching eats large doses of acid-activated clay and the finished oil still misses the red color grade (Lovibond red) your buyer demands.Solution. Tianyuan powdered carbon, run as a clay complement, adsorbs the pigments clay leaves behind — visibly pulling down Lovibond red while cutting your clay dose. Less clay, better color, lower bleaching cost per ton.
• Exporting palm oil to the EU means meeting strict PAH and aflatoxin limits. Bleaching earth alone does not reliably pull those down, and one failed lot blocks a whole shipment.Solution. High-activity coconut/nut-shell carbon strongly adsorbs PAH and aflatoxin from the oil, helping RBD palm oil clear EU export limits that clay alone cannot guarantee.
• High ash and iron in your carbon leach provxidant metals into the oil, accelerating oxidation and shortening shelf life — exactly what a palm-oil buyer tests for.Solution. Tight ash and iron control keeps the refined oil free of metal pickup and preserves its oxidative stability through storage and shipment.
• Heavy clay and poor carbon mean more neutral-oil loss trapped in the filter cake and more batch-to-batch drift in your recipe.Solution. High decolorizing power at low dose, with fine powder that filters fast and clean — lower oil loss, steadier recipe, lower total cost.

The Result Consistently lighter, cleaner RBD palm oil that meets red color grade and EU PAH/aflatoxin targets, with no metal contamination and lower bleaching loss — more on-spec and more exportable tons per ton of crude.
