  • How is palm oil refining improved?
  • In this context, refining technologies have been improved, with the dual temperature deodo-rizer, the double condensing unit and the ice condensing system. The DOBI is a good tool to assess quality of the crude palm oil and its ability to be properly refined.
  • Why is initial palm oil acidity important?
  • The results revealed that initial palm oil acidity is a statistically important parameter to obtain commercially acceptable values for final FFA content. The increase of temperature presented the most important effect on the reduction of all nutraceutical compounds.
  • How is palm oil refined?
  • Palm oil is generally refined by the physical process, which is preferred over the chemi-cal one, since high acidity can lead to excessive losses of neutral oil in the soaps-tock after alkali neutralization. However, chemical refining is still used at a limited capacity.
  • Is crude palm oil a good quality oil?
  • A crude oil with a DOBI above 3 can be considered as an oil of very satisfactory quality. Its a matter of fact ’ that good-quality refined oils can not be produced from low quality oils. A bleachability test was developed (table 2) to predict the final color of crude palm oil.
  • Why is palm oil a valuable feedstock for enzymatic interesterification?
  • Palm oil and fractions are also valuable feedstock for enzymatic interesterification in which applications are for commodity oil (low-trans margarines and shortenings) and for special products (cocoa butter equivalents, infant formulation, ...). Crude palm oil is produced from palm fruit by cooking, pressing and clarification.
  • What are the side effects of crude palm oil?
  • DOBI (min.) Carotene (ppm max.) Fe (ppm max.) Cu (ppm max.) Table 2. Influence of crude palm oil quality on the final color of physically refined palm oil (260 °C/3 mbar/50 min.). The unwanted side effects are the formation of trans fatty acids, polymerization, acyl-migration and degradation of natural vitamins and anti-oxidants.
