The samples were categorized in categories on the basis of properties which include moisture content, free fatty acid amount, kinematic viscosity and saponification value.
The oily extracts obtained were subjected to density, kinematic viscosity, acid value, pour point, cloud point, flash point, fatty acid profile, iodine value and saponification value.
Also, the viscosity, density, saponification value and iodine value (IV) are different when virgin oils are used (Tomasevic, Siler-Marinkovic 2003).
