摘要
目的监测油炸面食品中铝含量,评价其食品安全风险。方法在重庆市西部地区12个区县中随机抽取大足县、铜梁县、璧山县、沙坪坝区4个区县作为监测县,每个监测区县按东、西、南、北4个方位分别随机抽取餐馆、小食店等油条和油饼各6~10件,每件500 g,送璧山县疾控中心实验室,按GB/T5009.182-2003《面制食品中铝的测定》中铬天青S分光光度法定量检测铝含量。结果共检测渝西地区4区县油条和油饼各120件,铝检出率油条为100%,油饼为93.3%,总平均铝含量油条为537.4mg/kg,油饼为144.1 mg/kg,两者间差异有统计学意义(t=10.63,P<0.01)。4区县平均铝含量油条为328.5mg/kg^654.1mg/kg,铜梁、璧山、大足3县与沙坪坝之间差异有统计学意义,3县之间差异无统计学意义;油饼为99.8 mg/kg^170.2 mg/kg,4区县之间差异无统计学意义。按国家卫生标准铝含量超标率油条为97.5%,油饼为42.5%,两者差异有统计学意义(χ2=83.83,P<0.01)。结论渝西4区县油炸面食品铝含量高,尤其是油条,平均超过国家食品卫生标准4倍多,存在食品安全风险,有关部门应予高度重视。
Objective To monitor the content of aluminum in fried wheaten foods and to evaluate the food safety risk. Methods Three counties and one district were randomly selected from all the 12 counties /districts in western Chongqing,and 6- 10 samples of fired wheaten foods collected from eateries and snack shops,each weighed 500 grams,were tested in the lab of Bishan County Center for Disease Control and Prevention with methods of spectrophotometric according to GB /T5009. 182- 2003. Results Totally 120 samples were detected,with a detectable rate of 100% in deep- fried dough sticks and 93. 3% in deep- fried dough cakes. The total average content of aluminum in deep- fried dough sticks was 537. 4mg /kg and 144. 1 mg /kg in deep-fried dough cakes,with a statistical difference between the two（ t = 10. 63,P〈 0. 01）. The average aluminum content in deep- fried dough sticks ranged from 328. 5 mg /kg to 654. 1 mg /kg in the four areas,and statistical difference were found between Shapingba district and the other areas of Tongliang,Bishan and Dazu county; yet no statistical differences were found among the latter mentioned three counties. The content of aluminum in deep- fried dough cakes ranged from 99. 8 mg /kg to 170. 2 mg /kg,with no statistical differences among the four areas. According to national food hygienic standard,the over standard rate of aluminum in deep- fried dough cakes was 97. 5% and 42. 5% in deepfried dough sticks,with statistical difference between the two（χ2 = 83. 83,P〈 0. 01）. Conclusion The aluminum content in fried wheaten foods is high,especially in deep- fried dough cakes,with averagely three times higher above the national standard,which indicates a food safety risk and deserves high attention from relevant departments.
