Palm pressed-fibre oil (PPFO) is known as a phytonutrients rich oil. PPFO was practically recycled back to the crude palm oil (CPO) processing line to increase oil extraction rates. This study evaluated the effect of blending CPO with PPFO at different PPFO dosage from 5-25 (w/w) on blended oil quality.

Abstract

Palm pressed-fibre oil (PPFO) is known as a phytonutrients rich oil. PPFO was practically recycled back to the crude palm oil (CPO) processing line to increase oil extraction rates. This study evaluated the effect of blending CPO with PPFO at different PPFO dosage from 5-25 (w/w) on blended oil quality. Free fatty acid (FFA) of blended oils increased from 3.42-3.91 while deterioration of bleachability index (DOBI) and iodine value (IV) decreased from 2.76 to 2.33 and 51.96 0.37 to 50.21 0.03 respectively. Minor components amount in blended oils were found to increase with carotenoids (539-654 ppm) squalene (475- 1201 ppm) sterols (433-808 ppm) phospholipids (34.67-63.84 ppm) and vitamin E (1185-1626 ppm). The oxidative stability of blended oils was improved (14.31-16.76 hr) but chlorine iron and copper content were found to increase from 3.85-7.49 ppm 13.58-17.63 ppm and 0.19-0.38 ppm respectively. Although blending PPFO would deteriorate some quality properties of CPO nonetheless PPFO is rich with phytonutrients therefore signifying its potential applications in pharmaceuticals and food industry.
