Abstract
We attempted to microencapsulate hem iron particles by fatty acids to give functionality, such as masking black color and water resistance. In the experiment, lauric acid, myristic acid and palmitic acid were used as shell materials and methyl cellulose (MC) and casein sodium (CS) were used as dispersants. Multicore-type and monocore-type microcapsules were prepared by addition of MC and CS, respectively. Furthermore, by addition of CS, the microencapsulation efficiency, black color masking and water resistance were significantly improved.
