[en] The objective of the research was to study the effect of limonin core to coating ratio on eficiency limonin and stability of limonin microcapsules in aqueous pH 4 dan 7. Maltodextrin Dextrose Equivalent 10 was chosen as encapsultant with core to coating ratio 1 : 10 and 1 : 20. Stability of limonin microcapsule in aqueous pH 4 and 7 was investigated for 14 days. Microencapsulation was conducted using freeze dryer. Microcapsules surface was analyze using Scaning Electron Microscope and the result show limonin microcapsule with core to coating ration 1 : 20 had better appereance and uniformity in size. Limonin content was measured using spertrofotometry method. Result showed limonin microencapsulation with core to coating ratio 1 : 10 had efficiency of 81, 3% while ratio 1 : 20 had efficiency of 83,5%. Maltodextrin was unstable at aqueous pH 4 and limonin in microcapsule with core to coating ratio 1 : 10 start released at day 6. While limonin microcapsule with core to coating ratio 1 : 20 start to release on day 4 at aqueous pH 4 and on aqueous pH 7, microcapsule start to release on day 10. (paper)
