中文摘要:

      重金属元素是食品安全领域重要的检测项目, 目前, 用于检测重金属的仪器主要有原子吸收光谱仪、原子荧光光谱仪、电感耦合等离子体发射光谱仪、电感耦合等离子体质谱仪(inductively coupled plasma mass spectrometer, ICP-MS)等。ICP-MS具有线性范围宽、灵敏度高、精密度好、检出限低、可同时分析多种元素等优点, 广泛应用于医学、生物学、食品安全等多种领域。本文综述了近年来电感耦合等离子质谱法在食用油、面制品、乳及乳制品、水产品、果蔬及其他食品检测中的应用, 并对该领域的发展前景进行了展望, 以期为ICP-MS技术测定食品中重金属的检测发展提供一定的参考价值。

英文摘要:

      Heavy metal elements are important testing items in food safety field, the instruments for the detection of heavy metals include atomic absorption spectrometer (AAS), atomic fluorescence spectrometer (AFS), inductively coupled plasma atomic emission spectrometer (ICP-AES), inductively coupled plasma mass spectrometer (ICP-MS). ICP-MS has the advantages of wide linear range, high sensitivity, good precision, low detection limit, and can analyze many elements at the same time, so it is widely used in medicine, biology, food safety and other fields. This paper reviewed the application of inductively coupled plasma spectra in the detection of edible oils, flour products, dairy products, aquatic products, fruits and vegetables and other foods, and prospected the development prospect of this field. In order to provide a certain reference value for the determination and development of heavy metals in food by ICP-MS technology.
