  • How is crude coconut oil refined?
  • Refinement is usually used to remove undesired components to improve coconut oil quality. In the present study, crude coconut oil (CCO) was refined in four stages: conventional degumming, neutralization, bleaching, and deodorization.
  • What are the steps involved in the coconut oil refining process?
  • Crude coconut oil needs to be refined into bright and high quality coconut oil that meets national standards before it can be sold. There are mainly four steps involved in the refining process of coconut oil: degumming, deacidification, decolorization and deodorization.
  • Does the refinement process affect the quality of coconut oil?
  • The influence of the refinement process on the quality of refined, bleached, and deodorized coconut oil (RBDCO) has rarely been investigated. Moura and Jose revealed that unsaponifiable matter and total sterol content decreased during coconut oil refinement (Moura Fé 1971).
  • Is coconut oil chemically refined?
  • In chemical refining, mono- tively higher affinity for water. However, coconut oil is rarely chemically refined. Because of the high initial FFA content, physical refining is mostly preferred for lauric oils (11–13). long-chain fatty acids (e.g., palm, corn, and rapeseed oils). tillates are considerably higher. ing physical refining of coconut oil.
  • Does Physical refining of coconut oil cause neutral oil loss?
  • In the present study, neutral oil loss (distillative and mechanical carry-over) during physical refining of coconut oil was quantified. Neutral oil loss seems to depend on both the crude oil quality and the process conditions during deodorization.
  • What is the difference between chemical and physical deacidification of coconut oil?
  • In the coconut oil refining process, chemical deacidification involves adding lye to the oil in deacidification equipment to neutralize it and remove Free Fatty Acids (FFA). On the other hand, physical deacidification uses high temperature water vapor to remove FFA from the oil through distillation.
