• How is crude coconut oil refined?
  • J Food Sci Technol. 2019 Jun; 56 (6): 3109¨C3116. 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.
  • 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 F¨¦ 1971 ).
  • 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%.
  • How is coconut oil extracted?
  • Coconut oil is essentially extracted from copra or dried coconut, mostly by pressing. Specially designed oil expellers generate heat and pressure to the copra pieces that ease oil oozing out of the samples. These result in brown-coloured crude oil that must be purified in further steps to obtain refined organoleptically accepted coconut oil.
  • Does microwaving 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%. This result shows that when microwaving was implemented the yield of coconut oil extracted can be increased by 9.58%.
  • How does edible oil refining reduce production costs?
  • In edible oil refining, the continuous effort to reduce overall production costs is mainly achieved by increasing plant capacities, installation of mono feedstock plants, and increasing the degree of automation. Over the years, more energy-efficient processes and technologies, resulting in a higher refined oil yield, have gradually been introduced.
