Abstract

The usage of NIRS to determine oil quality parameters for palm oil is not entirely novel as studies have been carried out to determine the suitability of using NIR wavelength for Iodine Value IV free fatty acids FFA peroxide value -carotene palm oil residue in palm kernel methyl esters and palm oil methyl esters. It has also been used to study oil loss in palm oil mills by analysing residual oil content in press fibre palm oil sludge steriliser condensate and empty fruit bunches. The application of NIRS for routine analysis in oil palm breeding is an interesting prospect given i the larger range of values obtained in analysis due to genetic variation compared to samples obtained from commercial bulk ii the ability to perform analysis with minimal sample preparation and without the usage of organic solvents iii the advantage of analysing multiple parameters for crude palm oil samples simultaneously. In this study we developed calibration models for Oil to Dry Mesocarp ODM Iodine Value IV and -carotene content using conventional methods as reference data. Furthermore a validation step was performed using independent set of samples. In brief the sample number n coefficient of determination r2 for i calibration ii validation and iii standard error prediction SEP were satisfactory i.e. n573 r20.959; n442 r20.889; SEP1.284 for ODM n1238 r20.978; n3051 r20.892; SEP0.978 unit for IV and n728 r20.978; n142 r20.952; SEP54.491 ppm for -carotene.
