Edible Oil Refining

Powder activated carbon is used in refining rice bran, palm, sunflower, and specialty oils — removing colour, odour compounds, and trace contaminants. Water-washed grades are mandatory: acid-washed carbon introduces free acid that can damage the oil.

How It Works

The process, step by step

Bleaching step

Carbon is added to oil at elevated temperature (80u2013110u00b0C) along with bleaching earth, in a bleaching vessel under vacuum.

Contact & mixing

Carbon contacts the oil for 20u201330 minutes. Colour bodies and odour compounds adsorb onto the carbon surface.

Filtration

Bleached oil passes through filter press. Carbon and bleaching earth are removed. Oil meets colour specification.

Key Specifications

Wash type

Water-washed only

Acid-washed carbon introduces free fatty acid into oil u2014 water-washed is the mandatory specification

Particle Size

200 or 325 mesh

Finer particle size gives more surface area per gram and improves contact efficiency in oil

Decolorisation

>85% (Lovibond)

Lovibond colour reduction test in standard oil at defined dose and temperature
