电子鼻技术在食品检测中的应用

Research and Application of Electronic Nose in Food Inspection

随着嗅觉传感器技术的不断发展,电子鼻技术得到了广泛的研究与应用。电子鼻由气敏传感器阵列、信号处理子系统和模式识别子系统等3种功能器件组成。为此,阐述了电子鼻技术的结构组成,介绍了其在食品新鲜度检测、果蔬成熟度评价及饮料与酒类识别等轻工业中的应用现状与发展趋势,并指出了这些新技术实现过程中所需要解决的问题。

With the development of olfaction sensors sensors, many research and applications have been made in the electronic nose. The electronic nose consists of an array of gas sensors with different selectivity patterns, signal handling and pattern recognition and decision strategy. Measurement data from the artificial smell and taste sensors are used to produce sensor-specific opinion about these two human-like sensing modalities. This paper is introduced the configuration and basic principle of electronic nose, at the same time, current research situation and applications of the electronic nose in the food industry have been introduced in details. It is also given that the theoretic and technology problem which should be solved.
