Glutaraldehyde (GA) crosslinked gelatin (G) microcapsules containing Zanthoxylum limonella oil (ZLO) were prepared by coacervation technique. The effect of various parameters such as variation of oil-loading, gelatin concentration and degree of crosslinking on release rate of oil were studied. Scanning electron microscopy (SEM) was used to understand the surface characteristics of microcapsules. FTIR-results indicated the absence of any significant interaction between polymer and oil.
