Effect of fractionation temperatures on the physicochemical properties of palm stearin and palm kernel oil blend / Nur ‘Athiyah Abdul Jamil

The physicochemical properties of palm stearin (PS), palm kernel oil (PKO), 1:1 palm stearin palm kernel oil (PSPKO) blend and their fractions were evaluated in terms of their physical and chemical properties. The 1:1 PSPKO blend was subjected to dry fractionation at three different temperatures and...
