CLARITY OF SINGLE AND DOUBLE FRACTIONATED PALM OLEINS

NOR AINI, I.*; HANIRAH, H.*

ABSTRACT

The clarity of single and double fractionated palm oleins of different iodine values (IV) were studied. At 5°C, all samples crystallized within a day; two samples (DfPOo IV 65 and 67) were cloudy while the rest became solid. On the other hand, all samples were clear at 20°C except SfPOo IV 56 and 58. Samples DfPOo IV 62, 65 and 67 remained clear at 20°C until day 60. Fatty acid composition and the content of diglycerides seemed to have an influence on the clarity of palm oleins.

CRYSTALLISATION BEHAVIOUR OF PALM OLEINS

The tendency for palm oleins to cloud when subjected to cold temperatures has long been a problem for the palm oil industry. In the present study, the crystallisation behaviour of palm oleins was evaluated by means of differential scanning calorimetry (DSC), X-ray diffraction and nuclear magnetic resonance (NMR) spectrometry. While the ratio of saturated to […]
