Abstract

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 to optimize a good calibration equation for determination of amylose content in small amount of rice grain. The standard error of calibration (SEC), standard error of cross-validation (SECV) and regression squared (RSQ) of the calibration selected were 1.489, 1.761 and 0.885.

Key words: NITS, Rice grain, Amylose content（AC）
