To produce refined palm oil (RPO), the objectionable impurities in the CPO are removed to obtain the required levels using two main methods: chemical or alkali refining and physical refining methods. Either of these is followed by fractionation as a final purification process to separate the oil into stearin and olein components.
What is crude palm oil refining?
To prevent iron oxidation, the storage tank is lined in a suitable protective coating. The oil at this stage is called the crude palm oil (CPO). The aim of refining is to convert the CPO to quality edible oil by removal of objectionable impurities to the desired levels in the most efficient manner.
Why is improvement of palm oil plantation necessary before refinery process?
Improvement of oil palm plantation, fruit harvest and oil extraction process in palm oil mills is necessary before the refinery process so that hydrolysis reactions that produce MAG and DAG and chlorine contamination can be minimized in crude palm oil (CPO).
What is crude palm oil (CPO)?
Crude palm oil (CPO) is obtained from the fruit of the oil palm tree ( Elaeis guineensis ). The oil is rich in palmitic acid, ¦Â-carotene and vitamin E. CPO has been fractionated mainly into liquid palm olein and solid palm stearin in order to diversify its food applications.
