This study was conducted to determine the origin of roasted peanuts. The roasted peanut discriminative analysis was conducted based on data that was analyzed using the non-destructive analysis methods ED-XRF and NIRS(48 domestic and 23 imported samples). The results of the ED-XRF analysis showed that out of 71 cases, two imported samples were classified as domestic while all other samples were correctly classified, showing a 97.2% reliability of the discriminative rate. In the case of the NIRS-based approach, one domestic sample was classified as imported, indicating a 98.6% identification rate when the identification was performed using the sample absorption spectra. In conclusion, the results of this study showed that both the ED-XRF and NIRS analysis data could be potentially useful for determining the geographical origin of roasted peanuts when the discriminant analysis is applied by statistical analysis.
