Process parameters for chironji nut (Buchanania lanzan.) decortication

Buchanania lanzan (Chironji) a member of family Anacardiaceae consist of a hard nut that on decortication yields kernel containing 52% of oil and this oil is used as a substitute for olive and almond oil. Also, kernel is used for sweet meals, medicinal purpose, cosmetics etc. By manual decortication the capacity was observed to be minimum and recovery of whole kernel was nearly 12% only. This manual method is time consuming, laborious, inefficient and there is fear of injury to fingers. Decortication of chironji nut is a major problem and hence this valuable chironji kernel is to be procured at high price i.e. Approx. Rs.700-1000, whereas the chironji nut could be purchased at the rate of Rs. 100 to 150/kg. As the kernel is valuable, it was necessary to get maximum recovery during decortication so as to reduce the cost. Thus, considering all the facts related to the valuable kernel, decortication followed by drying of nut has been studied in detailed to obtain maximum recovery of good quality kernels. The RSM technology is applied for optimization of process parameters. Optimization of process parameters using response surface methodology (RSM) greatly overcomes the numbers of experimental trials generally undertaken for decorticating study of chironji nuts apart from maximizing the output of the system. | Process parameters for chironji nut (Buchanania lanzan.) decortication
