  • How to extract virgin coconut oil from coconut kernel?
  • Extraction of virgin coconut oil from coconut kernel is a major influential step for their commercialization. There are many extraction methods, among which cold and hot extraction are conventional extraction processes.
  • What is coconut oil extraction method?
  • The wet milling process, also known as cold pressing, is another prominent Coconut Oil Extraction Method. Unlike solvent extraction, this method protects the nutritional integrity of the oil as it involves minimal heat, consequently preserving sensitive molecules like antioxidants and vitamins present in the oil.
  • Do extraction methods affect the quality of coconut oil?
  • It was observed that extraction methods had significant influence on both the oil yield and quality of coconut oil; the quality attributes of the oil were comparable to acceptable standards for vegetable oil.
  • How to extract coconut oil?
  • There are two methods used in extracting coconut oil: cold process and hot process. In cold process, the coconut milk strained from the freshly grated coconut flesh was refrigerated for 10 to 17 hours. After refrigerating for several hours, the milk was removed out of the refrigerator and was let to rest until it reaches room temperature.
  • What is the difference between cold and hot extraction of coconut oil?
  • In cold process, extraction of coconut oil takes place through destabilization of coconut milk emulsion without heating such as fermentation, chilling and thawing, or centrifugation, enzymatic treatment. Hot extraction processes has been provide better yield than cold extraction processes.
  • How to increase the yield of coconut oil extracted?
  • Based on the research conducted by Wong in year 2010, a combination of microwave and centrifugation can be used to increase the yield of coconut oil extracted. At a microwave power of 720 W and a centrifugation speed of 12,000 rpm and a centrifugation time of 105 min, the yield of coconut oil extracted is at 46.88%.
