目的：建立一种简便易行测定油炸食品中铝的方法。方法：用改进后的铬天青S分光光度法测定铝含量。结果：改进后的方法线性范围由国标法的0～6μg提高到0～10μg，线性关系良好。曲线的回归方程为：Y=0.1174X-0.0236，相关系数0.9997，加标回收率93.0％～106.2％，方法的检出限0.37mg/kg。结论：改进后的铝含量测定方法简便，容易控制，结果精确。“,”Objective:To establish a simple determination method of aluminum in fried food. Methods:To determine the content of aluminum in extruded food with improved methods of chrome azurol S spectrophotometry. Result:Increased the linear range of the national standard method from 0 ~ 6μg to 0 ~ 10μg with the improved method. There was a linear relationship.The curve regression equation was Y=0.1174X-0.0236,the correlation coefficient was 0.9997, the recovery rate was between 93.0% ~ 106.2%, the detection limit was 0.37mg/kg. Conclusion:The improved aluminum determination method is simple, easy to control, resulting in accurate.
