The first survey on palm fatty acid distillate (PFAD) from local refineries was carried out in 1983. In 1999, a similar survey was conducted and palm kernel fatty acid distillate (PKFAD) were included in the study.

 

The first survey on palm fatty acid distillate (PFAD) from local refineries was carried out in 1983. In 1999, a similar survey was conducted and palm kernel fatty acid distillate (PKFAD) were included in the study. There has been a nine-year lapse since the last survey, and this article intends to update the information pertaining to the quality and the composition of the distillates. Results from this update for PFAD, indicated that the quality in terms of iodine value, conventional mass per volume, titre, trace metal contents, saponification value and compositional data (e.g. free fatty acids and unsaponifiable matter), have remained almost unchanged over the years. However, partial glycerides were found to be two times higher than that in the last survey, but with less consistent quantities and the same increase was also observed in the contents of tocopherols and tocotrienols. In the case of PKFAD, while most of the quality remained almost unchanged, there was, however, an obvious drop in the iodine value and free fatty acid content compared to the previous surveys.
