Abstract

The purpose of this study was to determine the encapsulation efficiency and cumulative release of red ginger oleoresin from microcapsules with different wall materials. Red ginger oleoresin was added to the maltodextrin solution, followed by a tween 80. The mixture formed was transferred to a spray dryer for the drying process. Other materials used are carrageenan and a combination of maltodextrin and carrageenan in a ratio of 1:1, 2:1, and 1:2. Red ginger oleoresin microcapsules were analyzed for encapsulation efficiency and release test using phosphate buffer medium pH 7.4, then determine release kinetics using zero-order, first-order, Higuchi model, Korsmeyer-Peppas model, and Peppas-Shalin model. The highest encapsulation efficiency was 78.6%, and the lowest cumulative was 58.46% from microcapsules with a wall material of a mixture of maltodextrin and carrageenan with a ratio of 1:2. The release kinetics best fit the Korsmeyer-Peppas and Peppas-Shalin models with anomalous transport (non-Fickian) and Fickian diffusion release mechanisms.
