文摘The industrial chemistry of oils and fats is a mature technology, with decades of experience and refinement behind current practices, therefore some physico-chemical characteristics of eleven vegetable oils sunflower oil （four different manufacturing companies）, olive oil （three different manufacturing companies）, corn oil, castor oil, coconut oil and canola oil in Iraqi Kurdistan region （Hawler city center） have been evaluated according to association of official analytical chemists （AOAC） （1995） official methods. The refractive index, viscosity, acid value, peroxide value, pH values, and values of specific gravity of the vegetable oil samples were measured at various different conditions. The results showed that some of the oil samples have unacceptable values in comparison with the standards.
