摘要： The present invention relates to a method for multidimensional evaluation of the similarity of a sample to breast milk, wherein the method is performed in the following steps: (1) establishing a local breast milk phospholipid database; (2) collecting and pretreating a sample to be evaluated; (3) determining the contents of characteristic phospholipid subclasses, the contents of characteristic phospholipid molecules in the sample to be evaluated, and obtaining a microstructural image of milk fat globules in the sample by confocal laser scanning microscopy; (4) calculating the score G for the sample to be evaluated. The present invention evaluates the similarity of samples to breast milk based on phospholipids in three aspects: the composition of characteristic phospholipid subclasses, the composition of characteristic phospholipid molecules, and the morphological similarity evaluation, so that the scheme can better evaluate the simulation quality of infant formulas and their raw and auxiliary materials to breast milk based on phospholipids.
