Physicochemical properties of black cumin seed oil

Abstract

The main goal of this research was to study the physical and chemical properties of black cumin seed oil .one kg of black cumin seeds were milled, were collect the powder was kept for further analysis .The oil extracted by petroleum ether and the result revealed that the physical properties of black cumin seed oil contain viscosity 40.12cp , density 0.906 , refractive index 1.463 ,colour 1.0333 , 10.343(R.Y.B)while the chemical properties peroxide value 1.7033 (mgo2/g) ,saponification value 186.55(mg/g) ,iodine value 97.733(mgI2/g),acid value 0.396 (mgKOH/g), saponification 1.51(mg/g)from the previous physicochemical tests of black cumin seed oil could be used for edible purpose because it proved to be of high nutritional value.
