Research on the Chemical Fingerprinting of Infant Formula Powder Based on Liquid Chromatography-Quadrupole/Time-of-Flight Mass Spectrometry and Chemometrics
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.
