| Abstract: | The model of determining sesame moisture was built using near infrared spectroscopy(NIRS) and the FOSS system as the analyzer.The influences on the model of factors,such as the mathematics methods and optics treatment methods were studied.The calibrations of the moisture content in sesame were also performed.The results showed that the best factors were SNV only for optics treatment method and "2,4,4,1" for mathematics method.The square error of cross(SEC),the average determination coefficient of validation(RSQ),the square error of cross validation(SECV),the correlation coefficient(1-VR),the average determination coefficient of validation(RSQ) and the standard error of prediction(SEP) were 0.0430,0.9933,0.1434,0.9254,0.941 and 0.238,respectively.This model could determine the moisture content in sesame used as a rapid and lossless method to detect the quality of sesame seeds. |
