摘要：
The microencapsulation of jasmine oil with polymethyl methacrylate (PMMA) was carried out by solvent evaporation method in oil in water (O/W) emulsion system. The oil phase was formed by the mixing of PMMA, jasmine oil and toluene and then dispersed in polyvinyl alcohol solution as stabilizer. After solvent evaporation, PMMA microcapsules with encapsulated jasmine oil were formed. The influence of weight ratio of PMMA: jasmine oil on the preparation of polymer capsule was studied. It was found that using 1:1 weight ratio of PMMA: jasmine oil, the polymer capsules could not prepared. The increase of PMMA content resulting in the formation of spherical PMMA microcapsules as in the case of 2:1 and 3:1 weight ratios. The amount of encapsulated jasmine oil and the encapsulation efficiency was measured with UV-visible spectroscopy. Approximately 72% encapsulation efficiency was obtained. (C) 2014 Elsevier Ltd.
