  Abstract

This study was carried out in order to optimize the condition of microencapsulation with natural sea buckthorn fruit oil as core and chitosan-arabic gum as wall material by coacervation method using response surface analysis. As independent variables, the rate of sea buckthorn fruit oil, the rate of emulsifier (Tween 80), stirring speed, and stirring duration entered the regression models to maximize microencapsulation yield, and to minimize particle diameter mean and particle size distribution. As results, the models suggested that 4.48(wt%) as sea buckthorn fruit oil rate, 4.58(wt%) as the rate of Tween 80, 10,354 rpm as stirring speed, 3.34 second as stirring duration could be the optimized conditions to produce chitosan-arabic gum microcapsules containing sea buckthorn fruit oil with better predictable for particle size diameter of microcapsules. The microcapsules prepared under the optimized conditions were shown to have thermal stability by TGA and to exhibit a little release rate of oil till 70 hours have passed.
