Palm pressed fibre oil: A new opportunity for premium hardstock?

Palm pressed fiber (PPF) is a by-product from oil extraction of oil palm fruits. It has unique characteristics resulting from the combination of palm mesocarp fiber, kernel shell and crushed kernel. The present study on different extraction methods for PPF indicated that conventional hexane cold extraction would be the more preferable method compared to soxhlet and reflux method due to the yield recovered (4.35%) and diacylglycerol (19.93% ± 0.07) obtained. Acylglycerol composition using cold extraction gave high Diaclyglycerol and Triacylglycerol (67.04% ± 0.05) with reasonable amount of Monoaclyglycerol / Free Fatty Acid (13.02% ± 0.02). Lauric acid which was not present in crude palm oil were found to be significant in PPF (5.89 to 9.09%), thus making this oil suitable for application in the food industry in products such as shortening and margarine.
