 ABSTRACT

         Cashew nut oil is basically extracted from the fruit of cashew by the cold pressed method. The cashew nuts have a shell which has a hard layer inside and an oily layer outside. The cashew nut is actively contained within this. The oil comes out of the outer ashy colored shell. This oil is basically considered as toxic for the human beings but still, it has various uses. Four methods were used in caring out the chemical properties of cashew nut. The methods are Saponification value, Acid value, peroxide value, and Iodine value.
