电子鼻技术在果蔬检测中的应用

Application of electronic nose technology on the detection of fruits and vegetables

电子鼻技术作为一种新兴的智能仿生技术,在工业和农业方面都得到了广泛的研究与应用,具有样品处理简单、检测速度快、识别效果好、实时、无损的优点。由于电子鼻具有满足农产品品质无损检测要求等优点,电子鼻系统正在被越来越多地运用到农业研究之中。本文介绍了电子鼻的发展史和一些常见的电子鼻型号,其中典型的有PEN3型和FOX4000等。分析了电子鼻系统的组成构造,介绍了电子鼻系统的工作原理。其中重点阐述了电子鼻技术在水果与蔬菜中的研究与应用。在农业生产过程中,电子鼻在对区分果蔬的不同类型与品种、合理地制定与调整果蔬的贮藏时间和条件以及鉴别与评价果蔬品质等方面有着很大的帮助。最后,主要针对电子鼻技术在农业中的应用,从多个方面对电子鼻技术存在的问题及其发展趋势进行了探讨。

Electronic nose technology, as a new intelligent bionic technology in terms of industry and agriculture, has been studied and applied widely, and it has some advantages such as samples on processing simply, fast testing velocity, good recognition effect, real-time and nondestructive. Because the advantages of electronic nose can meet the requirements of quality nondestructive testing of agricultural products, the electronic nose system are being increasingly applied to agricultural research. Firstly the development history of the electronic nose system and different models of electronic nose were introduced in this paper, including the typical PEN3 and FOX4000, etc. Then the structure and composition principle of the electronic nose system was explained. The research and application of electronic nose technology in fruits and vegetables were expounded as the major content. Electronic nose had great effects on the processing agriculture production. The aspects could be summarized by the distinction about the varieties of the fruits and vegetables, the reasonable formulation and adjustment of fruit and vegetable storage time and conditions and the evaluation of quality of fruits and vegetables. Finally, in view of the electronic nose technology were used in agricultural products, this paper discussed the problems of electronic nose technology and its development trend from several aspects.
