The invention relates to the technical field of functional fat processing, in particular to a method for preparing fat microcapsules by a low temperature electrostatic spray drying method, and a method for producing fat microcapsules through nitrogen-charged low temperature electrostatic spray drying. The method comprises the steps of preparing materials, dissolving wall materials, preparing corematerials, pre-emulsifying the wall materials and the core materials, performing high-pressure homogenizing and performing spray drying. The fat microcapsules for infant formula milk powder, producedby the method disclosed by the invention, are high in oil content, can be stored at normal temperature for 2 years or above, and can be stored at 63 DEG C in a sealed light-away manner for 1 month, and the physical and chemical indexes of products conform to the national standard. The entrapping rate of the obtained perilla herb oil microcapsules disclosed by the invention is as high as 98% or above, compared with microcapsule products prepared by a traditional spray drying method, the fat microcapsules are lower in initial peroxide value and acid value, more stable in quality, simpler in technology and higher in operability, and large-scale continuous production is easy to realize.
