Abstract—In this investigation, the water-soluble sulphite parison with a wide variety of microencapsulation encapsulated using ethylcellulose phase separation and then techniques. Phase separation method has been used essfully ethylcellulose microcapsules were used as core material to prepare in the preparation of drug delivery systems which were always dual coated microparticles using melting scattered condensation made from natural and biodegradable polymers such as method. Morphology of microencapsulation was observed by ethylcellulose [3]. In addition to protecting the core, the scanning electron microscopy (SEM). Release profiles of SO2 from encapsulation provides controlled release. Therefore, the release sulphite microparticles were also studied. The results showed that performances of core from encapsulated powder are quite the rates of SO2 released from microparticles were not only affected important for its application [4,5]. by varying the type, but also by the relative humidity in the Only few s
