| 摘 要： | 在反相色谱条件下,采用液相色谱-飞行时间串联质谱技术检测了18种婴幼儿配方乳粉,并应用主成分分析技术对大量的实验数据进行统计分析处理,研究了不同数据提取参数对分析结果的影响,通过T值检验筛选出3种罐标显示添加水解蛋白的婴幼儿配方乳粉的特征组分,提出了其中G号样品的16个特征组分的化学信息,并构建了相关的化学指纹图。

| Abstract: | 18 infant formula powder samples were analyzed by RP LC-Q-TOF MS,and potential chemical markers were filtered by PCA.Different parameters for pretreatment on the results of data analysis were studied.The characteristic components of partially hydrolyzed protein in infant formula powder were found by T-test.The chemical information of 16 characteristic components in G sample was proposed,and the correspongding chemical fingerprinting was constructed. |
