Abstract: To establish the quantification method for 23 low-molecular-weight organic components(nucleotides,nucleosides,organic acids and amino acids)in infant formulas,quantitative nuclear magnetic resonance(qNMR)technique was employed based on processing approach of global spectral deconvolution(GSD).The results revealed that it showed a good linear correlation for 23 components in the given concentration ranges(R²=0.9960~0.9997),with the RSD of precision between 1.02%~3.72%,the RSD of repeatability between 1.34%~3.68%,the RSD of stability between 1.62%~3.20%,and the recovery rate between 85.02%~110.00%.The choline content determined by this method was compared with the national standard method,and the results were consistent(RSD<15%).The results indicated that GSD-qNMR method was better than the traditional qNMR method,and was more suitable for the quantitative detection of low-molecular-weight organic components in complex food matrix such as infant formula.
