  • 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.
  • 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 is coconut milk extracted?
  • There are many extraction methods, among which cold and hot extraction are conventional extraction processes. The hot extractions carried out by pressing the clean, ground and fresh coconut, to yield coconut milk followed by heating at high temperature that could remove the useful micronutrient.
  • How is coconut powder extracted?
  • Samples ranging from 0.424 to 1.5 mm were obtained by sieving. This process is a semi-batch process with a continuous flow of carbon dioxide at a flow rate of 3 mL/mins. The coconut powder is charged into the extractor along with the carbon dioxide.
  • 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%.
