High molecular weight sodium alginate (HMWSA)/low molecular weight sodium alginate (LMWSA) microcapsules containing phytoncide oil were prepared with different LMWSA contents. The effects of the stirring rate and ratio of HMWSA/LMWSA on the diameter and morphology of the phytoncide/alginate beads were investigated by optical microscopy and the release behaviors of phytoncide oil from the phytoncide/alginate beads were characterized by UV/Vis. spectrophotometry. The mean particle size of the phytoncide/alginate beads decreased with increasing stirring rate and concentration of the calcium chloride solution. The surface morphology of the phytoncide/alginate beads changed from smooth surfaces to skin-like rough surfaces with increasing LMWSA content. These results were due mainly to the increased hydrophilic groups at the bead surface, resulting in an increase in the release rate of phytoncide oil in the phytoncide/alginate beads.
