In the palm oil industry, various methods used for the control of product quality are of interest. The palm kernels sold to the kernel crushing factory should strictly adhere to the sales specifications of kernel mentioned in the sales agreement that stipulates the minimum allowable contamination of dirt and moisture in the kernel consignment. After crushing the kernel to extract the kernel oil, the residue called expeller is analysed for the residual oil and contaminant content. The percentage residual oil content in the expeller will give the extraction  fficiency of the kernel extraction plant. The production kernel oil also undergoes analyses as it also has to meet the sales specifications on quality. Similar analysis is also conducted by the kernel oil efinery when it receives the kernel oil from the kernel crushers. Currently, all the important tests to monitor product quality in the palm oil mills, refineries, kernel crushing plants and kernel oil refineries are carried out using lengthy procedures. This can be a set-back for timely quality control of the products as the time lag could cause the production of off-quality products for long periods. Until recently there were no instruments that could analyse the quality parameters that are critical in a continuous production line.
