| 摘 要： | 根据信阳市2004～2007年茶文化节名优绿茶连续四届的感官质量评比结果,运用生物统计软件SAS9.0进行数据处理结果:五项审评因子间,外形与其他四因子间的相关性不明显,汤色与香气、滋味、叶底的相关性显著;与品质总分(Y)的关系,滋味(X4)﹥香气(X3)﹥汤色(X2)﹥叶底(X5)﹥外形(X1);加权评分,色23分、香23分、味24分、形(包括干茶和叶底)30分的比例较为合理。并运用DPS数据软件处理,使用逐步回归建立各因子与品质总分间的相关方程为:Y=25.8852+0.731X1+0.702X2+1.02X3+1.2204X4+1.03X5。

| Abstract: | The factors of tea sensory evaluation by biological statistical software SAS9.0 were conducted according to the results of sensory evaluation from Tea Culture Festival in Xinyang city from 2004 to 2007.Results showed that the correlation between liquor color and aroma,taste,infusion was significant,but the correlation between appearance and the other factors was not significant.It was showed that the taste﹥aroma﹥liquor color﹥infusion﹥appearance in comparing with total quality score.The score proportion of color 23,aroma 23,taste 24,appearance 30 was rather reasonable.The correlative equation of each factor and total quality score was established by the method of stepwise regression with the DPS data processing software as follows: Y=25.8852+0.731X1+0.702X2+1.02X3+1.2204X4+1.03X5 |
