摘要
应用电子舌传感技术和多元统计学方法相结合的手段,本研究对市售6个啤酒品牌下15个样品的滋味品质特征进行综合评价分析。结果表明,评价啤酒品质的8种滋味指标可以划分为三大类,其中第一主成分由酸味、鲜味和鲜味的回味组成;第二主成分由苦味和苦味的回味组成;第三主成分由咸味、涩味和涩味的回味构成。因子分析发现综合得分排名前三的啤酒样品分别为C_1、F_1和E_1。与此同时,通过聚类分析可以将15个不同品牌与类型的啤酒样品按照滋味品质的差异情况分为5类,与现有啤酒市场行情相符。研究说明电子舌传感技术在啤酒品牌区分、品质口感判定和市场分析中具有巨大的应用潜力。
In this study, the taste profile characterizations from 15 beer samples, including 6 different beer brands on the market, were evaluated by both the electronic tongue and multivariate statistical analysis tools. The results indicated that 8 kinds of beer taste profile in our research could be divided into 3 types. The first principal part was comprised of sourness, umami and richness. And the second was characterized by both bitterness and aftertaste-B; and the third is consisted of saltiness, astringency and aftertaste-A. Furthermore, the top three of beer samples were C1, El, and F~ respectively evaluated by factor analysis. Meanwhile, 15 beer samples could be divided into 5 types through clustering analysis, which was consistent with market conditions for beers.It could be concluded that the electronic tongue has great potential applications potential in quality distinguish and judge as well as the market analysis.
