Lipid powder having cross-linked coating thereon and process for preparing same

摘要

A lipid powder having a cross-linked coating thereon comprises a core lipid powder and a water-soluble coating agent coating the core lipid powder. The water-soluble coating agent contains cross-linked protein. A process for preparing lipid powders each having a cross-linked coating thereon comprises the steps of emulsifying lipid and a water-soluble coating agent containing protein to obtain an emulsion, adding a cross-linking agent for the protein the the emulsion to thereby cross-link the protein, atomizing and drying the emulsion containing the cross-linked protein to terminate the cross-linking reaction and to obtain lipid powders each coated with the water-soluble coating agent, and cooling the coated lipid powders.
