title: Preparation of egg albumin microcapsules and microspheres.
abstract: Protein microspheres and microcapsules containing fine hydrophilic particles (spherical silica gel beads, iron hydrous oxidemodified nylon 12, or phenacetin) were prepared by using water-soluble egg albumin, which is heat-coagulable at 50-80 degrees. The size and size distribution of the microspheres and microcapsules formed and the microencapsulation percentage of fine particles were determined, and the factors affecting them were studied. Favorable conditions are suggested to obtain phenacetin-containing microcapsules in high yield.
