The quality and quantity of amylose are two important factors that determine the quality of paddy. The feasibility of developing a technique for rapid monitoring of paddy quality by using Fourier Transform - Near Infrared (FT-NIR) Spectroscopy combined with chemometrics was investigated. Spectra of 250 paddy samples were collected by using an integrating sphere accessory. The amylose content was analyzed by reference method. It ranged from 13.24 to 27.93%. The spectral data was analyzed by partial least squares (PLS) algorithm and calibration model generated. Correlation coefficient (R2) for the calibration model was >0.78 with root mean square error of estimation (RMSEE) < 1.8. The validation model had R2> 0.72 and root mean square error of cross-validation (RMSECV) < 2. FT-NIR spectroscopy identified samples containing amylose at 5184 and 6834 cm-1 wave number. A fast, simple and accurate method to quantify the amylose of paddy was developed by using FT-NIR spectroscopy.
