The physicochemical and thermal properties of Malaysian high free fatty acid crude palm oil

This study was carried out to determine the physicochemical properties and the thermal behavior of Malaysian high free fatty acid crude palm oil (HFFA-CPO). The physicochemical properties showed that the free fatty acid (FFA %), acid value, iodine value, saponification value, unsaponifiable matter, hydroxyl value, specific gravity, refractive index at 28°C, moisture content, viscosity at 28°C and colour at 28°C values were 9.4±0.1 %, 21.3±0.1 mg/g, 50.6±0.2 mg/g, 203.1±0.1 mg/g, 0.7±0.1%, 43.4±0.2 mg/g, 0.878 g/ml, 1.4669, 0.6 %, 52 cP and 50R–40Y respectively. Gas chromatography (GC) was used to determine the fatty acid (FA) composition in HFFA-CPO. The fatty acids were found to be comprised mostly with 45.7 % palmitic acid (C16:0), 39.5 % oleic acid (C18:1), 9.4 % linoleic acid (C18:2) and 4.3 % stearic acid (C18:0). The analysis of triacylglycerol components with high performance liquid chromatography (HPLC) has resulted with 3.5 % triunsaturated (OOO, OLL and OLO), 32.7 % monosaturated (POO, PLO, SOO ...
