• What is edible oil refining?
  • Edible oil refining is the process of converting raw vegetable oil into edible oil. Raw vegetable oils, whether obtained through pressing or solvent extraction, contain unwanted components such as free fatty acids, phospholipids, and others, which cause undesirable flavors, odors, and appearances.
  • 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.
  • 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.
  • How is refined palm oil produced?
  • 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.
  • Why is palm oil refining important?
  • Furthermore, the refining process of palm oil is critical for maintaining its quality and extending its application range. It removes unwanted compounds while preserving beneficial components such as tocopherols [12, 13, 14, 15].
  • Is palm oil sustainable?
  • Palm oil, derived from Elaeis guineensis, is a critical component of the global edible oil and industrial fat market. This review provides a comprehensive overview of the sustainability of the palm oil chain, focusing on industrial applications, environmental implications, and economic sustainability.
