The Effect of Formulation Variables on the Encapsulation Efficiency and SO2-Release Behavior of Microparticles Containing Sulphite
The water-soluble sulphite was encapsulated using ethylcellulose phase separation. The effect of different process factors in the phase separation process on the encapsulation efficiency and the release profile of SO2 from the microparticles were evaluated. The results showed that the SO2 release from the microparticles containing sulphite was affected by the relative humidity in the microenvironment.
