In this study, NIRS and IRMS were used to determine the geographical origin of
Korean, American and Australian wheat flour. Results of NIRS analysis, the
classification achieved 98.8% of wheat flour samples assigned to the correct origin. The
mean 13C and 15N values were significantly different among the regions(p0.05).
However, 13C values seem more effective than 15N at determining the geographical
origin of wheat flour. The result demonstrated that application of NIRS and IRMS
along with statistical analysis could be used to discriminate the geographical origin of
wheat flour.
