中文摘要:

      液相微萃取是一种绿色环保的样品前处理技术, 具有选择性好、操作简单、快速、富集倍数高、所需有机溶剂用量少等特点而成为一种备受关注的新型样品分离富集技术。近些年, 该技术已经在水样、土壤、饮品及食品等样品的分析中得到广泛应用。本文综述了液相微萃取技术近期的研究进展及其在食品安全分析领域的应用, 包括饮品、蔬菜水果、谷物及动物性组织等食品中农药、兽药、酚类物质、持久性污染物及其他一些物质的分析检测, 并对其发展趋势进行展望。

英文摘要:

      Liquid-phase microextracion (LPME) is an environmental benign separation and enrichment technique because of good selectivity, simple operation, rapidity, high enrichment factor, and low dosage of organic solvent and so on. At present, it has been widely applied in the analysis of environmental water samples, soil samples, beverages, foods and so on. This present review focused on the updated developments of LPME and its applications in food safety analysis, including the determination of different substances like pesticides, veterinary drugs, phenols, persistent organic pollutants and others in beverages, fruits and vegetables, cereals, animal tissue and other foods. Finally, its development trend was prospected.
