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.
