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.
Is palm olein good for frying?
Matthaus (2007) reported that palm olein was comparable with high oleic vegetable oils and hydrogenated sunflower and cottonseed oils in terms of oxidative stability during frying. Palm oil is resistant to oxidation, polymerization and foaming. Palm oil does not produce any gummy or sticky residues in the fryer.
Does palm oil need a refining process?
However, the crude palm oil that has been extracted contains unwanted impurities and requires a refining process to partially or eliminate them to produce edible oil. In the current scenario, palm oil is widely used in tropical countries in South East Asia, Africa, and parts of Brazil for cooking purposes.
What machinery is used to refine palm oil?
Hence, here is a table showing machinery used to refine palm oil: A neutralizer works to reduce the free fatty acid (FFA) content in crude palm oil (CPO), improving its quality for various applications. This is achieved through a chemical reaction with an alkaline solution.
