摘  要:
世界上大部分的消费食品都受到微生物污染的影响。常用的微生物检测和鉴别方法存在一些缺点,不适用于食品的快速筛查。近年来,电子鼻为包括微生物污染诊断在内的食品品质与安全分析提供了有价值的分析手段。本文介绍了电子鼻的三个组成部分(气体采样单元、气敏传感器阵列、信号处理与模式识别系统),综述了电子鼻对食品中常见的细菌、霉菌、酵母和毒素等四种微生物污染类型的检测,最后对电子鼻的发展趋势和前景进行了展望。

摘  要:
Microbial contamination affected most of foodstuffs consumed in the world. Microbial detection and identification methods currently used had some typical drawbacks which made them unsuitable for routine rapid screening in foodstuffs.Electronic noses( E-noses) had recently emerged as valuable candidates in various areas of food quality and safety control,including microbial contamination diagnosis. The three components of e-noses,including sample handling system,detection system,and data processing and pattern recognition system,were described in this paper. Diagnosis cases of four kinds of microbial contamination based on e-noses in foodstuffs were presented:( a) bacteria,( b) moulds,( c) yeasts,and( d) toxins.Finally,recent trends and future directions of e-noses were illustrated.
