![]() It is used in industry as a raw material for brake lining compounds, as a water proofing agent, a preservative and in the manufacturing of paints and plastics. It yield two oils one of these found between the seed coat (or pericare) and the nut, is called the cashew nut shell liquid (CNSC). (Tiyadurai 1963).Ĭashew nut is a high value edible nut. ![]() Through the plant was primarily intended for checking soil erosion, it is now mainly grown for its commercially important kernel and shell oil. It was noticed that the tree grew well on poor sandy soils along the costal belt and was used by the Portuguese in Africa as an anti soil, erosion measure the tree prospered and spread naturally, particularly in East Africa and India and the progeny of these wild cashew has formed the basis of the raw material for the cashew industry. The cashew was taken to West Africa, East and India by the Portuguese in the 15th and 6th centuries. The cashew nut (Anacadium Occidentale) produces nuts, the Kernels of which have increase considerably in economic importance over the past few decades. The methods are Saponification value, Acid value, peroxide value, and Iodine value.ġ.1 Nutrient value/Composition of Cashew Nutġ.1.2 Total Nutrient content of cashew nutġ.4 Cashew Nut Shell liquid composition and properties.Ģ.0 Physio Chemical Properties of Cashew NutĢ.2 Analysis of Acid, Sponification and Iodine value in Cashew Nut.ģ.4.1 Preparation of Methanolic Pottassium Hydroxideģ.4.3 Preparation of 0.1 sodium thiosulphateģ.4.6 Preparation of 0.1m of NAOH (Sodium Hydroxide)ģ.4.7 Preparation of 0.5m Hcl (hydrochloric Acid)ģ.6.2.1 Determination of Saponification Value This oil is basically considered as toxic for the human beings but still, it has various uses.įour methods were used in caring out the chemical properties of cashew nut. The oil comes out of the outer ashy colored shell. The cashew nut is actively contained within this. ![]() The cashew nuts have a shell which has a hard layer inside and an oily layer outside. EXTRACTION AND DETERMINATION OF THE PHYSICAL CHEMICAL PROPERTIES OF CASHEW NUT OILĬashew nut oil is basically extracted from the fruit of cashew by the cold pressed method.
