![]() The cashew ‘fruit’ is very peculiar and is really not a fruit but a swollen pedicle that grow, behind the real fruit which yields, “the cashew (2, 3)”. The tree which is widely cultivated in Asia for its nuts and other products grows as tall as twelve meters with a thick and tortuous trunk and branches so winding that they frequently reach the ground. There has been growing interest in cashew and this can be ascribed to the purported dual role of the kennel: it can be used as a substitute for peanut and almond in the confectionery industry and as an important source of lipids and protein. The specie belongs to the class of the dicotyledons, order terebintals, family Anacardiaceae (1). ![]() Introduction The cashew tree (Anacardium occidentale L) is native to tropical America. The investment profile revealed that all the methods were viable, however the soxhlet method has the highest NPV (N227, 727 at 21% and N328, 678 at 32%) and BCR thus indicating its high returns on investment.ġ. The method of evaluation involved an investment decision model comprising Net present value (NPV), Benefit Cost Ratio (BCR) and Internal Rate of Return (IRR) quality parameters of the resulting oils were characterized. The Cost and return analysis of the three methods of expressing cashew kernel oil was also examined. The high value of 10.12 meq/kg obtained for aqueous method can be rationalized on the basis that traces of water cannot be completely ruled out and this result to hydrolysis of the ester bond of the triglyceride. The highest yield value of 48.8% was recorded for soxhlet method of extraction. While there is no significant difference in the value for specific gravity, moisture content, refractive index, viscosity ratio, melting point there are differences in value for chemical variables such as saponification value, iodine value and peroxide value. Parameters characterized included refractive index, melting point, viscosity ratio, acid value, iodine number, peroxide value, saponification value etc. The physicochemical characteristics of the resulting oils were assayed. Three methods of expressing cashew ( Anacardium occidentale L) oil from kernel were investigated.
