目的通过对小学生进行膳食摄入量问卷调查,估计小学生通过食物摄入丙烯酰胺的量,为了解小学生丙烯酰胺膳食暴露水平提供依据。方法采用自行设计的问卷,调查咸阳市623名小学生常吃食物的种类与数量,用气相色谱-质谱法测定常吃的22种高温加工食品中丙烯酰胺的含量,并根据检测结果计算被调查学生丙烯酰胺的摄入量。结果所检测食物中丙烯酰胺的含量范围为7~1 044μg/kg,其中薯片中丙烯酰胺含量最高。被调查小学生每人通过食物摄入丙烯酰胺的均值为(30.15±0.21)μg/d。不同性别摄入量差异无统计学意义(P>0.05),不同年级差异有统计学意义(P<0.05)。结论咸阳市小学生通过食物摄入丙烯酰胺的量相对较高,应该采取措施降低小学生的丙烯酰胺膳食摄入量。
Objective To assess the intake of acrylamide by food intake among primary school students by means of a questionnaire survey of dietary intake among primary school students so as to provide a basis for understanding the dietary exposure of acrylamide to pupils. Methods Self-designed questionnaires were used to investigate the types and quantities of food consumed by 623 primary school students in Xianyang City. The contents of acrylamide in 22 high-temperature processed foods were determined by gas chromatography-mass spectrometry. According to the test results, Acrylamide intake. Results The content of acrylamide in the tested food ranged from 7 to 1 044 μg / kg, of which the acrylamide content in potato chips was the highest. The mean value of acrylamide intake per person by food intake of primary school students was (30.15 ± 0.21) μg / d. There was no significant difference in the intake of different genders (P> 0.05). There was significant difference in different grades (P <0.05). Conclusion Primary school students in Xianyang City, through the food intake of acrylamide is relatively high, should take measures to reduce the intake of acrylamide dietary intake of primary school students.
