201 Deep-Fried Dough Sticks samples were detected, the total aluminum detection rate was 96.5%, exceed the standard rate of 65.7%. The annual samples of aluminum detection rate in more than 90%, median aluminum content were greater than 100 mg / kg, exceeding the rate were more than 50%, 2015 fritters excessive aluminum was higher than that in 2014 (x2=7.647, P = 0.006).
The highest detection value of aluminum in each annual sample was 2 times higher than that in the limit value, and the highest value of aluminum in 2015 was more than 4 times of the limit value. See Table 1
