目的分析成都市水发食品中甲醛含量并对其风险进行评估,从而指导消费及监管行为。方法对全市范围内水发食品中甲醛含量进行测定,结合成都市居民膳食消费数据,计算成都市居民甲醛暴露量及安全限值(MOS),采用点评估的方法开展成都市居民摄入水发食品中甲醛的风险评估。结果水发食品中甲醛含量差异较大,平均含量(中位数)为0.7 mg/kg,最大值为2 400.0 mg/kg。采用平均暴露量的点评估模型获得的畜禽血制品中甲醛急、慢性暴露的MOS分别为1 500、5 000,而采用高端暴露量的点评估模型获得的甲醛急、慢性暴露的MOS分别为2.5、6.7。结论成都市水发食品中甲醛摄入的急性、慢性风险是可以接受的。但从整个监测数据也反应出水发食品质量参差不齐,甲醛含量差距较大,个别食品中甲醛含量远远高于平均水平,均需要相关部门加强监管。
Objective To analyze the formaldehyde content of water food in Chengdu and evaluate its risk, so as to guide the consumption and regulatory behavior. Methods The content of formaldehyde in water-fat foods in the city was measured. Based on the dietary consumption data of Chengdu residents, the formaldehyde exposure and safety limit (MOS) of Chengdu residents were calculated. The methods of point assessment were used to investigate the water intake of Chengdu residents Risk assessment of formaldehyde in food. As a result, the content of formaldehyde in water-fat foods differed greatly. The average content (median) was 0.7 mg / kg and the maximum value was 2,400.0 mg / kg. The average daily exposure to formaldehyde and animal models of acute and chronic formaldehyde exposure were 1 500 and 5 000, respectively. However, the MOS for acute and chronic exposure to formaldehyde with high-end exposure was 2.5,6.7. Conclusion The acute and chronic risk of formaldehyde intake in water-fat foods in Chengdu is acceptable. However, the entire monitoring data also reflects the uneven quality of water produced foods, large differences in formaldehyde content, the individual food formaldehyde content is much higher than the average, both need to strengthen supervision of relevant departments.
