Ca-Alginate beads for microencapsulation of lime oil (Citrus aurantifolia) by ion-gel method was manufactured and then soaked in Chitosan solution to obtain Ca-Alginate-Chitosan beads. Increased CaCl2 concentrations reduced lime essential oil release. The alginate concentration (2 to 3%) and water temperature significantly affected the release of oil (P 0.05). In the storage of beads in 1% CaCl2 solution at normal temperature, after the first 15 days, Ca Alginate-Chitosan system released about 3% slower than Ca-Alginate system, but there was no difference between the two systems after 45 days. This shows that if prolonged for a long time, the ion-gelation of Ca-Alginate prevails over the Alginate-Chitosan cross-link.
