ABSTRACT:
The oil of coconut (cocos nucifera L.) was extracted by two different processing methods; aqueous (heating method) and solvent (soxhlet) extraction method. The physicochemical properties of the oil extracts were evaluated. The results showed that the density, specific gravity, viscosity and pH (aqueous extraction; 0.89 g/cm3, 0.91, 4.0 mpa.s, 4.7 and solvent extraction; 0.89 g/cm3, 0.91, 3.8 mpa.s, 5.1 respectively) of the oil extracts were relatively close. Other properties like the saponification value, free fatty acid, acid value and peroxide value of the aqueous and solvent extraction methods are 196.35 mgKOH/g, 0.56 mgKOH/g, 0.00028 mgKOH/g, 0.2 meq peroxide/g and 266.4 mgKOH/g, 0.95 mgKOH/g, 0.0047 mgKOH/g, 2.0 meq peroxide/g respectively..
