摘要
目的对乳粉中维生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13种维生素进行检测,在同一实验室对同一乳粉中的维生素进行重复检测确定产品的合格性;在不同实验室对同一乳粉中的维生素进行检测,发现实验室检测稳定性的差异。结果同一实验室对同一批次乳粉中维生素检测的稳定性较好,不同实验室间维生素稳定性相对较差。结论统一实验室检测方法,提升实验室检测水平,尽可能开发仪器检测方法,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。
Objective To analyze the stability of vitamins in milk powder. Methods According to the national standard method, the 13 kinds of vitamins that are necessary for GB 10765-2010 were tested. The qualification of the product was determined by repeated testing of the vitamin in the same milk powder in the same laboratory. The vitamin of the same milk powder was tested in different laboratories and the stability of the laboratory was detected. Results The stability of vitamin test in the same batch of milk powder was better in the same laboratory, and the vitamin stability was relatively poor in different laboratories. Conclusion Unifying laboratory testing method, improving laboratory test level, and developing instrument detection method as far as possible are the premise to ensure the stability of detection. It is helpful to provide accurate test data for the production of enterprises, which is of great guiding significance to the formulation of product formulation.
