Composite nutritive suspension and preparation method and application thereof

The invention relates to a composite nutritive suspension and preparation method and an application thereof. The composite nutritive suspension consists of a fatty fat containing emulsifying colloid solution and a powdery foundation bottom material, wherein fatty fat containing emulsifying colloid solution is prepared by mixing a water-soluble solution with a fat solution; and the fatty fat containing liquid is prepared through the steps of performing dissolving, performing emulsifying, performing homogenizing and the like, so that the emulsifying colloid solution of which the fatty fat is wrapped in the manner of granules is prepared, and then the colloid solution is mixed with the powdery foundation bottom material of carbohydrate, entire protein, or polypeptide and the like in the manner of a spraying-in method, so that the fat can be separated from air, and oxidation is avoided. The technology is stable, and quality guarantee period of products is prolonged. 本发明涉及一种复方营养混悬剂及其制备方法与应用，所述复方营养混悬剂由含脂肪油脂成分的乳化胶体溶
