- •
Carotenoids and chlorophylls were absorbed from rice bran oil in the bleaching step.
- •
Pigments adsorption kinetics was described by pseudo-second order model.

Freundlich and Langmuir models were evaluated in the equilibrium study.
- •
The thermodynamic parameters were obtained in the industrial temperature range.
- •
The rice oil bleaching process was endothermic, favorable and spontaneous.
