Deodorization technology of palm oil

Deodorization technology of palm oil

Deodorization is actually a stripping process in which a given amount of a stripping agent (usually steam) is passed for a given period of time through hot palm oil at a low pressure. Hence, it is mainly a physical process in which various volatile components are removed. However, since it is usually carried out at high temperature (> 200°C), some chemical, thermal effects may take place as well.

Palm oil contains various components, each with its specific volatility. In physical refining, it is mainly free fatty acids (FFA) that need to be stripped. Apart from FFA, other volatile components, either valuable (tocopherols, sterols, etc) or unwanted (off-flavors, pesticide residues, light polycyclic aromatic hydrocarbons, dioxins, etc), are also removed during deodorization.
