Objective To detect the content of aluminum in four kinds of noodle foods in Nanchong city and analyze the exposure of aluminum to the general population in Nanchong City. Methods Four kinds of noodle foods sold in Nanchong urban area were sampled and the samples were treated by ashing method. According to GB / T 5009.182-2003 “Determination of aluminum in noodle foods”, that is, chromazurol S colorimetric method Detection of aluminum products in flour content. According to the limit of contaminants in food GB / T 5009.182-2003 “Determination of aluminum in pasta food” hygiene evaluation. Results Among the 250 samples sampled, the total detection rate was 84.4%, in which the detection rate of aluminum was the highest (100.0%), followed by steamed bread (91.9%); the total exceeding standard rate was 22.0% (67.7%), followed by steamed bread (54.1%) and cake (18.7%). There was no excessive content of aluminum in the bread samples. The sampling area of the three areas, both in the fritters aluminum content exceeded the highest rate, followed by steamed bread, cake, bread in the detected content of aluminum did not exceed the national standard limit. Conclusions At present, the content of aluminum in steamed bread and fried dough sticks in Nanchong City is seriously over-standard, which should attract the attention of consumers and supervisory agencies.
