中文摘要:

      目的 统计分析2018年宁波市售的婴儿配方乳粉(1段乳粉, 适合于0-6个月婴儿食用)矿物质含量情况。方法 抽取市售婴儿配方乳粉150批, 对其中的12种矿物质元素进行检测, 分析产品中各矿物质元素的分布规律。检测结果与食品安全国家标准中的限量要求和《中国居民膳食营养素参考摄入量(2013版)》中相关参考值想对比。结果 所有元素实际含量均满足我国食品安全国家标准的限量要求, 但除铁外的11种矿物质含量均分布在标准限量范围的较低区间。与中国居民膳食营养素参考摄入量中给出的适宜摄入量比较, 硒、铜、钾、钠、碘5种元素均有不同比例的样品不满足适宜摄入量的要求。结论 目前市售婴儿配方乳粉存在矿物质元素不能满足婴儿生长发育需要的风险。建议国家结合欧盟等国外新修订婴儿配方食品标准, 同时充分考虑新版DRIs的要求, 尽快对食品安全国家标准进行修订。

英文摘要:

      Objective To statistically analyze the mineral content of infant formula milk powder (1 stage milk powder, suitable for infants aged 0-6 months) sold in Ningbo in 2018. Methods A totally of 150 batches of marketable infant formula milk powder were extracted and 12 mineral elements were detected to analyze the distribution rules of mineral elements in the products. The test results were compared with the limit requirements in the national food safety standard and the relevant reference values in “Reference intake of dietary nutrients of Chinese residents (2013 edition)”. Results The actual contents of all elements met the requirements of national food safety standards, but the contents of 11 minerals except iron were distributed in the lower range of the standard limits. Compared with the appropriate intake given in the reference intake of dietary nutrients of Chinese residents, samples with different proportions of 5 elements of selenium, copper, potassium, sodium and iodine did not meet the requirement of appropriate intake. Conclusion There is a risk that the mineral elements in commercially available infant formula will not meet the growth and development needs of infants. It is recommended that the country combine the European Union and other foreign countries to revise the infant formula standards, and fully consider the requirements of the new DRIs, and revise the national food safety standards as soon as possible.
