| Abstract: | Objective To evaluate the uncertainty for the determination of aluminum in deep-fried dough sticks by inductively coupled plasma-optical emission spectrometery (ICP-OES). Methods According to the evaluation principle and measurement method based on measurement uncertainty, the mathematical model of uncertainty in measurement was established, component calculation was conducted, and then uncertainty was determined. The uncertainty of measurement results was evaluated. Results The results of determination of aluminum in deep-fried dough sticks were 12.65 mg/kg, The expanded uncertainty was 0.53 mg/kg(k=2, P=95%). Conclusion The uncertainty of determination process mainly comes from the fitting of standard curve, repeatability test and the rate of recovery. |
