测定面制品中铝含量的方法结合与比较

Combination and Comparison of Methods for Determination of Aluminum Content in Flour Products

在检测食品中铝含量的方法中,常用的检测分析仪器设备有紫外分光光度计和电感耦合等离子体质谱仪,前处理方法分为干灰化法、湿法消解法和微波消解法。本文选用质控样品(饼干中铝)作为检测样品,使用3种前处理方法和两种检测仪器设备相结合测定铝的含量,分析比较各自方法的优缺点,以便筛选最适宜的测定方法。

In the detection of aluminum content in food,commonly used detection and analysis of instruments and equipment are ultraviolet spectrophotometer and inductively coupled plasma,mass spectrometry,pretreatment methods are divided into dry ashing method,wet digestion method and microwave digestion method.In this paper,the quality control sample (aluminum in biscuits) was selected as the detection sample,using 3 kinds of pretreatment method and the combination of two kinds of testing instruments and equipment for determining the content of aluminum,comparative analysis the advantages and disadvantages of each method,in order to screening the most appropriate method.
