| Abstract: | Rice stored at different conditions was analyzed by using an electronic nose（PEN 3）from Airsense Company in Germany.Through the PCA analysis,rice sample in different storage conditions were distinguished well,according to loadings analysis on the contribution rate of sensors,selected W1S,W2S,W5S,W3S,W1W,W2W as the new sensor array,results of analyzing the sensor response the values at 15℃,25℃,30℃ showed that values at 30℃and 25℃ were evidently higher than values at 15℃,moisture content also affected the response values of sensors evidently,at the same temperature,the higher moisture content was,the greater sensor＇s response value was.By Bivariate Dependency Analysis on the values of sensors response and the total number of mold colonies with the SPSS18.0,there were significant correlation at the 0.01 level between them.Based on qualitative analysis,results of making quantitative analysis of molds in rice with PLS method indicated that this way was feasible. |
