食品中重金属元素形态分析前处理与 检测研究进展
重金属的摄入可使人体的蛋白发生不可逆转的变性而危害人体健康。近年来, 食品中具有生物毒性的重金属含量越发受到关注, 但重金属的总量往往很难表示其污染特性及危害。食品中重金属元素形态决定其生物可利用率、毒性和迁移, 是食品安全检测关注的重要内容。本文从样品前处理、分析检测、联用技术等方面综述了食品中重金属的元素形态分析方法, 包括固相萃取等前处理技术、电感耦合等离子体原子发射光谱法等分析检测技术及高效液相色谱-电感耦合等离子体质谱联用等联用技术, 介绍了各种方法的原理、优点及不足。最后, 探究了其研究发展方向。生物、材料等领域的发展将推动重金属形态分析样品前处理技术的进步, 而联用技术将成为未来分析检测技术的发展方向。
The intake of heavy metals can make the proteins of human body occur irreversible degeneration and endanger human health. Biologically toxic heavy metals content received more and more attention in recent years, but the total amount of heavy metals are often difficult to represent the pollution characteristics and harm. Bioavailability, toxicity and migration of heavy metals in food were determined by the heavy metal elements form, which has become an important part of food safety inspection. Several aspects of speciation analysis of heavy metals in food, including sample preparation method, analysis and detection method, coupling technique were summarized in this review. Sample preparation method including solid phase extraction, detection method including inductively coupled plasma-atomic emission spectroscopy and coupling technique including high performance liquid chromatography-inductively coupled plasma-mass spectrometry were discussed. Moreover, their principles, advantages and disadvantages were introduced. The future development of speciation analysis of heavy metals in food was also prospected, in which the development of sample preparation method is driven by developments in the field of biology and materials and coupling technique will be the development direction of the future in the aspect of analysis and detection method.
