中文摘要: 通过电子鼻和电子舌对冷鲜牛肉外脊和大黄瓜条的不同加热温度 70、80、90、100、110、120 ℃炖煮 3 h 的风 味物质进行测定,将数据进行主成分分析(Principal Components Analysis,PCA)、线性判别分析(Linear Discriminant Analysis,LDA)、判别因子分析(Discriminant Factor Analysis,DFA)雷达图分析。结果显示:不同部位牛肉会产生很大的 影响, 电子鼻能够很好地分析出不同炖煮温度下外脊和大黄瓜条的风味,LDA 比 PCA 能够更好的区分出风味的变 化。电子舌能够很好地分析不同炖煮温度下外脊和大黄瓜条的风味得到 DFA 很好地分辨出口感变化,雷达图能直观 的展现出物质成分。

Abstract:Through the e-nose and e-tongue for cold fresh beef'flavor substances about ectoloph and siverside of the different cooking temperature 70,80,90,100,110,120 ℃ for 3 h, further analysis of the characteristics. Various data analysis of Principal Components Analysis PCA,Linear Discriminant Analysis (LDA), Discriminant Factor Analysis (DFA), radar chart. Results showed that: when cooking about different parts of beef will great influence. The analysis of (LDA) and PCA:the analysis of ectoloph and siverside about different temperatures of e-nose, LDA is better than PCA that can distinguish change between the flavor. The analysis of DFA and radar chart: the analysis of ectoloph and siverside about different temperatures of e-tongue can get dif- ferent taste, radar chart can directly show material composition.
