【摘要】：目的评估我国居民膳食中甜蜜素暴露水平及对我国居民健康状况的潜在风险。方法根据GB 2760—2014《食品添加剂使用标准》中规定允许使用甜蜜素的各类食品中甜蜜素的最大使用量和我国居民各类食品实际的消费量数据,采用简单分布模型方法,对我国居民全人群通过各类食品摄入甜蜜素的摄入量进行理论估计,并与国际组织制定的甜蜜素每日允许摄入量(ADI)进行比较。结果我国居民全人群每日通过各类食品摄入甜蜜素的平均水平为0.97 mg/kg BW,占ADI值的13.86%。高暴露人群(P97.5)每日通过各类食品摄入甜蜜素的量为6.69 mg/kg BW,占ADI值的95.52%。根据欧盟食品科学委员会(SCF)制订的ADI(7.00 mg/kg BW),各年龄组人群通过相应食品摄入甜蜜素的平均摄入量均未超过ADI值,但是2~3岁、4~9岁、10~17岁人群中的高暴露人群(P97.5)其甜蜜素的摄入量分别超过甜蜜素ADI的146.32%、86.78%、9.19%;糕点、带壳熟制坚果与籽类对我国居民膳食中甜蜜素暴露的贡献率较高。结论我国居民全人群通过GB 2760—2014中规定允许使用甜蜜素的各类食品摄入甜蜜素的水平均处于安全水平,但是我国部分高暴露人群的暴露水平应引起关注。
[Abstract]:Objective to evaluate the exposure level of cyclamate and its potential risk to the health status of Chinese residents. Methods according to the maximum amount of cyclamate used in all kinds of foods permitted to use cyclamate in GB 2760-2014 and the actual consumption data of all kinds of food in China, a simple distribution model method was used. The intake of cyclamate in all kinds of food was estimated theoretically and compared with the daily allowable intake of cyclamate (ADI) developed by international organizations. Results the average daily intake of cyclamate in all kinds of food was 0. 97 mg/kg BW, which accounted for 13. 86% of ADI. The daily intake of cyclamate in high exposure population (P97.5) was 6. 69 mg/kg BW, / day, which accounted for 95.52% of ADI. According to the European Commission for Food Science (SCF), the average intake of cyclamate in all ages (7.00 mg/kg BW),) did not exceed the ADI value, but it was 2 or 3 years old, 4 to 9 years old. The intake of cyclamate in high exposure population (P97.5) of 10 ~ 17 years old was higher than that of cyclamate ADI (146.32%) and 86.78% (9.19%). The contribution of pastry, cooked nuts and seeds to the exposure to cyclamate in Chinese diet was higher. Conclusion the level of ingestion of cyclamate in all kinds of food which is allowed to use cyclamate in the whole population of our country through GB 2760-2014 is at the safe level, but the exposure level of part of high exposure population in China should be paid attention to.
