3种类型含乳饮料滋味品质的评价

         

摘要

In this paper, the taste profile characterizations of 3 kinds of milk beverage samples were studied by electronic tongue and multivariate statistics. Although principal component analysis(PCA), multivariate analy-sis of variance (MANOVA), and cluster analysis (CA) showed that there were significant difference in taste profile characterization of 3 kinds of milk beverage(P<0.05), formula milk beverage and the milk beverage fer-mented by S. thermophiles and L. bulgaricus had quite a lot in common. It was worth to mention that the taste profile characterization of the milk beverage fermented by probiotic strains were significant difference with 2 other groups. Meanwhile, sourness, umami, and richness were identified by redundancy analysis(RDA) as key variables significantly associated with the taste profile difference. We also found that sourness were significantly more abundant in the milk beverages fermented by probiotic strains(P<0.05), whereas umami and richness with higher content in the milk beverages fermented by S. thermophiles and L. bulgaricus(P<0.05).%采用电子舌技术和多变量统计学方法相结合的手段,对市售3种类型含乳饮料的滋味品质进行了评价分析。通过主成分分析、多元方差分析和聚类分析发现虽然3种类型含乳饮料样品其滋味品质整体结构存在显著差异(P<0.05),而S. thermophiles和L. bulgaricus发酵制备的含乳饮料整体滋味品质与配制型更为相似,且与益生菌发酵制备的有较大区别。通过冗余分析发现3种类型含乳饮料样品滋味品质整体结构存在差异是由于酸味、鲜味和丰度(鲜的回味)等3个指标导致的。通过Kruskal-Wallis分析发现,益生菌发酵型含乳饮料的酸味较高(P<0.05),而由S. thermophiles和L. bulgaricus发酵制备的含乳饮料鲜味和丰度(鲜的回味)较高(P<0.05)。
