Alginate Capsules for oil entrapment

Abstract

In this study, the drying condition for dried the Kaffir lime oil loaded alginate gellan gum macrocapsules (KLO-AG) and Kaffie lime oil loaded alginate gellan gum/TOBC macrocapsules KLO-AGT macrocapsules were determined at 50 and 60°C by observing their %weight loss. The results showed that the minimum drying hour for the KLO-AG and KLO-AGT macrocapsules was 2 and 3 hrs, respectively. Moreover, the 4 types of chitosan coated capsules were preparing and testing their physical and chemical properties. The results indicated that the capsules coated 2% w/v chitosan solution gave the best results in which highest shell thickness, compression strength and KLO loading. However, the release profiles of those coated capsules were not clear and repeat experiment was necessary.
