中文摘要:

      快速筛选技术是指包括样品制备在内, 能够在较短时间内出具检测结果的行为, 也称之为快速检测技术。随着我国食品安全问题广受关注, 快速筛选技术便成为研究的重点。快速检测目前主要应用于食品中农、兽药残留, 微生物致病菌, 营养成分, 不明污染物等针对食品安全的现场快速检测及常规检测。本文介绍了分子光谱法、免疫分析方法、酶抑制法和生物传感器等几种快速筛选技术的研究进展以及在食品安全检测等领域的应用。随着快速筛选技术的不断发展使得快速检测方法及其相关仪器产品种类越来越多且原理复杂, 快速检测方法的质量控制和方法验证显得尤为重要。本文重点阐述了快速筛选技术与方法的评价验证, 其主要技术参数包括: 敏感度、阴性和阳性界限值的准确性、选择性和特异性、检出限、定量限、重复性和再现性等, 并对其发展前景进行了展望。

英文摘要:

      Rapid screening technology means, including sample preparation, a kind of technology to be able to issue the test results in a short time. It was also defined as rapid detection technology. It was mainly used in food, pesticide, veterinary drug residues, microbial pathogens, nutrients, and unknown contaminants, etc. Rapid screening technology had become the focus of research as well as the food safety in our country. Several technologies of the rapid screening method were mainly introduced, including molecular spectrometry, immunoassay, enzyme inhibition method, and biological sensors, etc. With the continuous development of rapid screening technology, rapid detection methods and related equipment products appeared more and more, and their quality control and validation method turned to be particularly important. In this paper, the development and application of the rapid screening technology in food safety were expounded as well as its evaluation methods. Its main technical parameters included sensitivity, the accuracy of the negative and positive threshold, selectivity and specificity, detection limit, quantitative limit, repeatability and reproducibility, etc. The development in the future was prospected as well.
