Abstract:
This study analyzed human, goat, sheep, and pig milks using metabolomics, lipidomics, and proteomics, specifically untargeted LC-MS/MS metabolomics, untargeted LC-MS/MS lipidomics, and 4D-label-free proteomics. The aim was to determine differences among these milks and identify components with similar functions to human milk, providing a reference for the research and development of infant formulae. In goat milk, expression of lactoperoxidase, inosine, and allantoin were relatively high, while in sheep milk, concentrations of ceruloplasmin and alpha-ketoglutarate were higher. The content of linoleic acid (LA) was relatively high in both goat and sheep milks. A relatively high content of milk fat globule EGF factor 8 protein was found in pig milk.
