| 摘 要： | 该研究从市场上采集了隶属于18个品牌22个品名的甜面酱样品，并采用色度仪、质构仪、常规理化分析和多变量统计学方法相结合的手段对其品质进行了评价。研究表明甜面酱样品在红绿度（a*值）和黄蓝度（b*值）等指标上差异较大。通过聚类分析（CA）、多元方差分析（MANOVA）和典范对应分析（CCA）发现，市售甜面酱样品可以划分为3个聚类，经Kruskal-Wallis秩和检验发现隶属于不同聚类的样品其硬度、稠度、凝聚性和表观黏度等质构指标存在显著差异（P＜0.05）。

| Abstract: | 22 sweet fermented paste samples of 18 different brands were collected from market and the product quality of seasonings samples were studied by colorimeter, texture analyzer, common physical and chemical analysis and multivariate statistics. The results showed that there were significant differences in a* and b* value among samples. Through cluster analysis (CA), multivariate analysis of variance (MANOVA) and canonical correspondence analysis (CCA), the results showed that 22 samples could be divided into 3 clusters, and there were significant differences in hardness, consistency, cohesiveness and apparent viscosity of samples belong to different clusters (Kruskal-Wallis test, P＜0.05). |
