Analysis and Exposure Assessment of Aluminum Content in Fried Dough Stick in Shantou City from 2017-2023
Objective:To understand the aluminum content of fried dough stick in Shantou city from 2017 to 2023,evaluate the exposure risk of fried dough stick aluminum in Shantou city.Method:490 fried dough sticks samples were collected in Shantou from 2017 to 2023,and determined by inductively coupled plasma mass spectrometry(ICP-MS).Result:Aluminum was detected in 490 samples,the detection rate was 100%,the median was 237 mg·kg-1,and the content range was 1～1 731 mg·kg-1.The aluminum content in 202 deep-fried dough sticks samples was within the range of national standards,and the qualification rate was 41%.The results of dietary exposure assessment showed that the average aluminum intake through deep-fried dough sticks was 0.04 mg·kg-1 bw,significantly lower than the 2 mg·kg-1 bw specified by Joint FAO/WHO Expert Committeeon Food Additives(JECFA).Conclusion:The phenomenon that aluminum content in deep-fried dough sticks exceeds the standard is common in Shantou.The assessment of dietary exposure shows that the average intake of aluminum in deep-fried dough sticks is within the safe range,with less risk.
