• What is dry process of coconut oil extraction using dried coconut meat (copra)?
  • Seneviratne and Jayathilaka (2016) gave a description about the dry process of coconut oil extraction using dried coconut meat (copra), which involves drying of coconut kernels by reduction of water content from 50% to about 6% from coconut kernels.
  • What are the different types of coconut oil extraction methods?
  • Moving beyond the cold pressing and hot extraction methods, there is the centrifugation technique. This method uses high-speed spinning to separate the oil from the other components of the coconut meat. Unlike other methods, centrifugation does not use heat, which means the quality of coconut oil is not compromised.
  • What are the challenges faced by the industries in extracting coconut oil?
  • Challenges that are faced by the industries in extracting the coconut oil using different methods of extraction are important to be explored so that advancement in the oil extraction technology can be done for efficient downstream processing. This study is vital as it provides insights that could enhance the production of coconut 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.
  • 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.
  • How to extract virgin coconut oil using enzymatic treatment?
  • The destabilization of emulsion stability by collapsing protein bonds is required in order to yield virgin coconut oil (Patil and Benjakul 2019). The different methods of VCO extraction are briefly discussed below. Some authors have extracted VCO using enzymatic treatment by destabilizing the coconut emulsion with good recovery of oil.
