【摘要】 目的对营养包生产企业实验室的检测能力进行考察并对产品质量进行评估。方法抽取国内6家主要生产企业产品,参照CNAS-GL 005技术要求,制备考核样并检验其均匀性。在6家企业实验室进行室间比对,检测指标维生素A、维生素D₃、维生素B₁、维生素B₂、钙、铁、锌分别参照国标方法GB 5009.82-2016、GB 5009.82-2016、GB 5009.84-2016、GB 5009.85-2016、GB 5009.92-2016、GB 5009.90-2016、GB 5009.14-2017。结果通过单因素方差分析判别,考核样混合均匀;依据考核样检测结果进行Z评分,参与评估的6家企业检测能力均为"满意";实际产品检测结果与GB 22570-2014相比,除了1号实验室的产品2的钙元素结果含量略高于标准上限,其他含量均在国标许可范围内。结论我国主要的营养包生产企业基本具备把控产品质量的检测能力,抽检产品必需成分的含量符合GB 22570-2014相关指标限定值。更多还原

【Abstract】 Objective To evaluate the laboratory detectability of Chinese nutrition package and the quality of products.Methods The products of infantile complementary food packages were collected from 6 major manufacturers in China.According to the technical requirements CNAS-GL 005,blind samples were vortexed and checked its homogeneity.Proficiency testing by inter laboratory comparisons were performed.The test indexes included vitamin A,vitamin D₃, vitamin B₁,vitamin B₂,calcium,iron,and zinc,and the analysis methods were as follows:GB 5009.82-2016,GB 5009.82-2016,GB 5009.84-2016,GB 5009.85-2016,GB 5009.92-2016,GB5009.90-2016,GB 5009.14-2017.Results By One-way analysis,the samples were homogeneous.Z-score was used to evaluate the detection ability of the laboratories.All of the detection results were satisfied.Compared with GB22570-2014,the results were in the permission scope of national standards,except for the calcium content of Product2 in Lab 1 was slightly higher than the upper limit.Conclusion The main nutrition package manufacturers in China have the ability to control the quality of the products,and the content of the necessary components of the products is satisfied with the corresponding limits in GB 22570-2014.更多还原
