食品中锌的安全强化水平研究

目的研究提出食品中锌的强化水平上限建议值,为评估和修订食品营养强化剂标准提供参考。方法基于风险评估基本原则,利用2002年中国居民营养与健康状况调查数据,探讨应用强化水平上限计算模型,按不同经济发展水平、年龄、性别分层分析,得出不同组别人群的食品中锌强化水平上限,将其中的最低值作为强化水平上限的初步建议值。结果大城市、一类农村及中小城市中的大部分组别居民食品中锌强化水平上限(MSFL)低于全人群相应组别水平。最低的MSFL出现在大城市孕妇和4~7岁学龄前儿童组,分别为9.01mg/1 000kJ和10.43mg/1 000kJ。结论通过模型计算结果与食品强化标准相应指标值的比较分析,认为现有规定可以保证食用安全,该模型是评估和审议营养强化剂安全强化水平的可选方法。建议在今后的全国居民营养与健康状况调查中增加强化食品以及营养素补充剂的摄入情况调查。

Study on the maximum fortification level for zinc in foods

Objective To provide appropriate method and scientific suggestions for revising the maximum fortification level of Zinc.Method On the basis of the principle of risk assessment,a model adapted to China situation was developed to derive MSFL of Zinc for different age groups,sex and economic development level areas.The data of China National Nutrition and Health Survey in 2002 were used for this analysis.Results MSFLs for most groups of Large cities,M&S cities and Rural I are lower than those of the whole popu...
