Abstract: In order to protect the brand benefits of Wuchang rice, a total of 191 rice samples collected form Wuchang county and other places were identified by Fourier transform near infrared spectroscopy (FTNIS) combined with chemometrics. The results indicated that Wuchang rice and non-Wuchang rice were identified by factor analysis combined with FTNIS with 100% and 97.50% accuracy, by cluster analysis model with 100% and 100% accuracy, and by the quantitative analysis model developed using partial least squares (PLS) based on FTNIS spectra with 95.83% and 95.00% accuracy, respectively. It can be concluded that FTNIS combined with chemometrics is feasible to identify the geographical origin of Wuchang rice.

Key words: rice, geographical origin identification, qualitative analysis, cluster analysis, quantitative analysis
