Overview

Deodorization is basically a vacuum-steam distillation process in which a given amount of stripping steam is passed for a given period through hot oil that is kept at deep vacuum. It is usually the last stage of the refining process which various volatile components are removed. However, as it is carried out at high temperature, some others chemical and thermal effects may take place as well.

The principle of deodorization process has not changed much since its first application however the deodorizing technology itself has changed significantly. It has been steadily improved to increase process efficiency and better oil quality – light colour, bland odour, extended shelf life and contaminant free, particularly low in 3-MCPD and glycidyl esters.
