The global increase in demand for vegetable oils due to their nutritional, pharmaceutical, and industrial importance necessitates investigation on exploitation of new oil bearing crops. The results showed that the method of soxhlet extraction gave the highest yield and that the cashew nuts reject oil is non- drying, non - edible and can be employed for soap making, biodiesel production and other industrial uses. The oil yields are 40% and 26.66% for soxhlet and mechanical methods respectively.

The mean values of various parameters for proximate composition (%) obtained were: moisture content (8.90 + 0.2), crude protein (22.10 + 0.2), crude fiber (0.90 + 0.3), ether extract (40.23 + 0.1), ash content (3.73 + 0.1), Nitrogen free extract (24.04), tannin (1.02) and phytic acid (0.50). The oil was extracted using Soxhlet and mechanical methods separately the proximate composition and physicochemical characteristics of the oil were investigated using standard analytical methods. Cashew nut (Anarcadium occidentale) reject is a waste material from cashew nut processing industry usually regarded as non valuable.
