Abstract: One hundred and twenty-four samples of small amount of rice grain were scanned by Foss Tecator Infratec 1255, and
their amylose contents were determined by chemistry method. With the WINISI calibration maker software, several mathematics
treatments to the sample spectra and several different regression methods were adopted t
