Abstract

The main objectives of this project is to study the fundamental idea of retention volatile organic on coating materials with spray drying process. Many studies had been done in the retention of complex materials in microcapsules but only few in the pure or single component. Maltodextrin and xanthan gum were used as the microencapsulating agents and methanol as the core materials in this study for volatile retention using spray drying process. The volatility retention of the core component in different coating materials was studied using gas chromatography/mass specthrophometer analysis. The results showed that the retention volatility is directly proportional with the concentration of microencapsulating agent. The high concentration of the agent leads to the formation of thicker wall to encapsulate the methanol. The morphology of the microcapsules produced were observed using scanning electron microscopy (SEM), the analysis collected is mainly showing a tendency of agglomeration. The microcapsules sizes are ranging from 3 µm to 6µm and the data was obtained from particle size image analyzer.
