传感器型电子鼻技术在谷物品质研究中的应用进展

Application of Sensor Electronic Nose in the Research of Grain Guality

电子鼻技术是一种综合的气味分析技术,由样品处理系统、检测系统、数据处理系统三部分构成,根据检测系统不同分为传感器型电子鼻、气谱型电子鼻和质谱型电子鼻。通过对传感器型电子鼻前处理条件优化和电子鼻传感器列阵优化来得出较好的PCA结果,以区分谷物霉变程度、储藏时间、虫害情况以及感观品质。

Electronic nose technology is a comprehensive odor analysis technique and by the sample processing system,detection system,data processing system is composed of three parts. According to the detection system,there are three different types of electronic nose which are mass sensor electric nose,GC electric nose,mass spectrometry-based electric nose. In order to distinguish the moldy corn status,storage time,insect pest and sense of quality,the optimization of pretreatment conditions and electronic nose sensor array need to be done to get better results of PCA.
