中文摘要:

      电子鼻技术是近年发展起来的一种新型仿生嗅觉检测技术, 因其具备快速、无损等优点被广泛应用于食品品质检测领域。电子鼻通常包括两部分: 硬件部分——多个性能彼此重叠的气体传感器; 软件部分——恰当的模式识别技术对采集信号的分析、处理。本文主要综述了近年来国内外电子鼻技术在肉类品质分析中的应用。首先阐述了电子鼻技术工作原理、数据处理方法, 随后重点讨论了电子鼻技术在肉类新鲜度评定、肉与肉制品品质区分、肉类有害成分监测、肉类掺假检测等4个方面的应用进展, 最后对电子鼻技术目前存在的问题及未来发展趋势进行了简要探讨。

英文摘要:

      Electronic nose is a kind of novel bionic olfactory detection technology developed in recent years, which has been widely applied for food quality testing due to its rapid, non-constructive advantages. In general, the electronic nose includes two parts: the hardware part—an array of gas sensors to obtain the signals of different smell; the software part—the appropriate pattern recognition technology for analyzing and processing the measured signals. This paper focused on the current development of electronic nose technology for the analysis of meat quality at home and abroad, briefly introduced the working principle and data processing of the electronic nose, and discussed the applications of electronic nose in predicting the meat freshness, testing the quality of meat, monitoring the harmful compounds in meat and detecting the adulterated meat. At last, the existing problems and the future development of the electronic nose were dis-cussed briefly.
