摘要:
Provided is a manufacturing method of particles coated with coatable microparticles. The method is a manufacturing method of particles coated with coatable microparticles, comprising the step of adding the coatable microparticles to an inner core comprising a component of interest and a macromolecule, and, while rolling the mixture, coating the mixture while spraying a solvent that can dissolve the macromolecule, wherein the particles coated with the coatable microparticles are coated, component of interest-containing hollow particles.
