中文摘要:

      目的 对乳粉中矿物质元素检测的稳定性进行分析研究。方法 依据国标方法对GB 10765-2010中必需要求的12种矿物质元素进行检测, 在同一实验室对同一乳粉中的矿物质元素进行重复检测确定产品的稳定性; 在不同实验室对同一乳粉中的矿物质元素进行检测, 发现实验室检测稳定性的差异。结果 发现同一实验室对同一批次乳粉中矿物质元素检测的稳定性较好, 不同实验室间矿物质元素检测稳定性相对较差。 结论 统一实验室检测方法, 提升实验室检测水平, 是确保检测稳定性的前提, 有利于为企业生产时提供准确的检测数据, 对制定产品配方具有重要指导意义。

英文摘要:

      Objective To analyze the stability of minerals in milk powder. Methods According to the national standard method, 12 mineral elements required in GB 10765-2010 were tested, and the stability of the product was determined by repeated testing of the mineral elements in the same milk powder in the same laboratory. The mineral elements of the same milk powder were tested in different laboratories, and the stability of the laboratory was detected. Results It was found that the same laboratory had better stability in the detection of mineral elements in the same batch of milk powder, and the stability of mineral elements in different laboratories was relatively poor. Conclusion Unifying laboratory testing method, improving laboratory test level are the premise to ensure the stability of testing. It is helpful to provide accurate test data for the production of enterprises, which is of important guiding significance for formulating product formulations.
