  • Do you need a centrifuge for peanut oil refining?
  • It is common to use a day tank holding enough oil for one day refining needs and also allows analysis of the crude needed for the lot of oil (color, free fatty acids, and gums). Part B shows the refining sequence. As peanut oil is not degummed, a centrifuge for separation of gums is not needed.
  • What is the basis for Prime crude peanut oil?
  • Basis for prime crude peanut oil: must refine to a red color of 10 (AOCS) and with a loss of weight below 12%, with moisture and insolubles less than 1%. Settlements are made in accordance with rule 201 which provides discounts for oil not meeting prime crude (off color, refining loss, free fatty acids).
  • Where does peanut oil come from?
  • Peanut (groundnut, earth nut) oil production worldwide was about 5.4 million metric tons (MMT) in 2012/2013 and has remained fairly static over the past decade ( USDA, FAS, 2014 ). Worldwide, peanut seed production amounts to about 37 MMT primarily from China, India, US, Nigeria, and Indonesia with the remainder 15% from 15 other countries.
  • What are the rules for crude peanut oil?
  • Crude peanut oil is covered under Rules 175¨C179 as summarized below: Prime crude must be made from sound peanuts; be sweet in flavor and odor; must produce prime yellow oil when refined by these rules with a loss not less than 5%; combined moisture and insolubles not to exceed 1% by American Oil Chemists Society (AOCS) test methods.
  • How do you remove peanut Phosphatides from crude oil?
  • An early study on the recovery of peanut lecithin ( Helme and Desnuelle, 1948) on an industrial scale from solvent-extracted crude oil showed that peanut phosphatides can be efficiently removed by controlling the amount of water employed in the degumming step.
  • How many metric tons of peanuts are crushed in the US?
  • In 2014, 291,000 metric tons were crushed for oil (12%) in the US. A large portion of the US peanut crop is utilized as whole unshelled/salted peanuts and in peanut butter. Only four crushing plants in the US process peanuts into oil/protein with expeller pressing the technology of choice.
