Abstract:The product qualities of mustard collected from Sichuan， Zhejiang， and Chongqing were studied by taste， texture quality， physical and chemical index， and multivariate statistics. The results of Kruskal-Wallis indicated that moisture content of samples collected from Chongqing were significantly higher than those in Sichuan （P < 0.05），but the index of protein content showed the opposite trend （P < 0.05）. Although principalcomponent analysis（PCA）， canonical correspondence analysis（CCA）， cluster analysis（CA）， and multivari－ ate analysis of variance （MANOVA）all showed that there were significant difference in mustard samples pro－ duced from different regions （P＜0.05）， the mustard samples produced from Sichuan and Zhejiang had quite a lot in common. Thus， it could conclude that the regions have significant effects on the product profile characteri－ zations of mustard.
