摘要
针对婴幼儿食品和乳制品中维生素B12测定方法(GB5413.14—2010),分析国标的实验关键点。虽然微生物测定方法不易掌握,但通过实验经验归纳总结和实验关键点控制,GB5413.14—2010方法精密度和重复性都可以得到理想结果。本研究对于质量分数甚微的维生素B12测定、低于仪器最低检出限的维生素测定、具有生物活性的维生素的测定具有一定指导意义。
Analyze critical points of the method that Determination of vitamin B12 in foods for infants and young children, milk and milk products（GB5413.14-2010）. Although the microbiological method is not easy to master, but through summarizing experiences and controlling experimental critical points, the satisfactory results of Method precision and repeatability of GB5413.14-2010 can be obtained. The paper may offer few suggestions for detecting low content of vitamin B12, lower than the instrument limit of detection of vitamin B12 and biological activi- ty of vitamin B12
