摘　　要：针对国标方法检测特殊医学用途婴儿配方食品中VB1、VB2、VB6、烟酸的适用性进行分析。7家实验室采用高效液相色谱法,分别对3类配方,8种特殊医学用途婴儿配方食品和婴幼儿配方奶粉质控样品中的VB1、VB2、VB6和烟酸进行测定,同时进行回收率测定。结果表明,国标方法适用于婴幼儿配方奶粉中VB1、VB2、VB6、烟酸的测定,适用于特殊医学用途婴儿配方食品中VB1、VB2和VB6的测定。VB1回收率偏低,VB2的深度水解配方和氨基酸配方的产品回收率偏低,烟酸检测的数据普遍不理想。本研究为特殊医学用途婴儿配方食品的检测方法建立起到了一定技术支撑。In this study,the applicability of the Chinese national standard methods to detect vitamin B1,vitamin B2,vitamin B6,and niacin in infant formula for special medical purposes was explored.High performance liquid chromatography(HPLC)was used to determine vitamin B1,vitamin B2,vitamin B6 and niacin in eight samples of three types of infant formula foods for special medical-purpose and infant formula milk powder quality control samples in seven laboratories.The recovery rate was also measured.The results showed that the national standard methods were suitable for the determination of vitamin B1,vitamin B2,vitamin B6,and niacin in infant formula milk powder,and for the determination of vitamin B1,vitamin B2 and vitamin B6 in infant formula for special medical purposes.The recovery rate of vitamin B1 was low.The recovery rate of vitamin B2 in deep hydrolysis formula and amino acid formula products was low,and the test data for niacin was generally unsatisfactory.This study provides technical support for the establishment of methods for testing infant formula for special medical purposes.
