  • How is coconut oil extracted?
  • Traditional methods of coconut oil extraction primarily revolve around using heat or a simple mechanical pressure. These rudimentary methods often yield a lesser quantity of oil and could affect the quality. However, over time, these methods have evolved significantly.
  • What are the different types of coconut oil extraction methods?
  • It’s important to note that coconut oil extraction methods can be broadly categorized into two types – dry and wet extraction methods. Dry extraction, which includes methods like copra drying, generally involves sun-drying the coconut meat to evaporate water content before pressing to extract the oil.
  • What is the process of low-pressure extraction of coconut oil?
  • Figure 2 exemplifies the process of low-pressure extraction. Virgin coconut oil yield with 92.54% was obtained when the centrifugation time was set to 60 min and the centrifugation speed was set to 2700 rpm . Advantages of this method includes the by-products of this process, such as the coconut shells and husks may be used as fuel.
  • What are the different methods of oil extraction?
  • The most popular traditional method of oil extraction are cold extraction and hot extraction process. The challenges faced by these two processes include low yield of oil and the heating process in the hot extraction technique will cause a reduction in the antioxidant properties in oil.
  • What is solvent extraction in coconut oil production?
  • Solvent extraction, a relatively modern practice in coconut oil production, leverages organic solvents to separate the oil from raw coconuts. Particularly, hexane is popularly used due to its efficiency and high oil yielding capacity.
  • Which extraction processes are used in modern industries?
  • This review paper aims to highlight several common extraction processes used in modern industries that includes cold extraction, hot extraction, low-pressure extraction, chilling, freezing and thawing method, fermentation, centrifugation, enzymatic extraction and supercritical fluid carbon dioxide.
