The purpose of this study was to determine whether near-infrared (NIR) reflectance technology is reliable to be used as a rapid method for qualitative analysis of palm kernel cake. Six parameters were analyzed; moisture, ash, crude protein (CP), ether extracts (EE), crude fiber (CF) and nitrogen free extract (NFE). Palm kernel cake (PKC) samples (n = 48) were randomly selected from Feed Analysis Laboratory, Malaysia Veterinary Institute, Johor in year 2009, 2010 and 2012. CP was determined by the Kjeldahl method, CF was measured using Fibertec methods, and EE was measured using Soxtec methods. Each sample was also scanned with NIRFlex Model N-500. The data was analyzed using the SAS statistical program. Statistical significance of differences between means was tested by paired t-test analysis. A p-value of less than 0.05 (p<0.05) was considered statistically significant. There was no significant difference in the results from reference and test method for CP, EE, CF and NFE. These statistical analyses suggested that both methods can produce the same results for PKC sample. However, there are significant differences for moisture and ash result.
