Comparative Analysis of Similarity of Fatty Acid Composition between New Generation of Infant Formula and Breast Milk

Breast milk is the most ideal natural food for infants and the gold standard for the development of infant formula (IF). Accurately simulating the nutritional components of breast milk is an important means to improve IF. In order to better simulate breast milk lipids, a new generation of IF was developed based on the reported breast milk data, and then the total fatty acids and sn-2 fatty acids in breast milk and the new generation of IF were comparatively analyzed. The results showed that the new generation of IF and human milk were highly similar in total fatty acids and sn-2 fatty acids (the similarity coefficients were > 85% and > 70%, respectively). In conclusion, the new generation of IF can accurately simulate the total fatty acids and sn-2 fatty acids in human milk.
