电子鼻技术的研究进展及其在水产品鲜度评价中的应用

摘要

水产品的质量管理是水产加工企业的重要环节.传统上,水产品的鲜度主要是采用感官评价或气相色谱分析的方法进行的.这些方法费时昂贵,而且不便于对产品质量的适时监测.因此,高效、快捷的水产品质量监测技术的研究受到了很大关注.利用电子鼻监测水产品的鲜度,被公认是一种快速、可靠、可实现自动检测、而且对水产品无任何伤害的新型技术.本文阐述了电子鼻的工作原理和化学传感器技术的研究进展,并且讨论了电子鼻技术在水产品鲜度评价中的应用和未来发展前景.%Quality control of fishery product is of utnost importance to fishery product processing industry.Traditionally, the freshness of fishery product has been evaluated either by sensory organs or by gas chromatography that are expensive, time consuming and not suitable for real-time application. Development of an efficient and objective technique to monitor the quality of fish is therefore of increasing interest. Electronic nose has proven to be a rapid, automatic and non-destructive technique for measuring volatile compounds that exhibit spoilage odors in fish. The principle of electronic noses and the development of chemical sensor technology were described in this paper. The application of electronic noses in freshness assessment of fishery product and future prospect were discussed as well.
