Daftar Isi:
- Ginger essential oil distillation produces pulp which still contains oleoresin. In this study, the extraction of pulp gingeroleoresin was done for further exploitation. Microencapsulation was done to ease product handling and packaging. Theaim of this study was to determine the characteristics of the microcapsules of pulp ginger oleoresin. Pulp ginger oleoresinwas extracted using ethanol 96% as solvent with three variations of ratio (w/v)of 1:4, 1:5, and 1:6. Microencapsulationwas performed with spray drying technique using maltodextrin coating. In this study, there were three ratio of oleoresin: maltodextrin (1:50, 1:25, and 1:16,7). The results showed that the highest microencapsulation efficiency of pulp gingeroleoresin was attained by the ratio of 1:16,7. This microcapsule had a water content of 6.37% (db), water activity 0.20,bulk density 0.46 g/ml, solubility 622.33 seconds, total oil 42.62 x10-2 g/g microcapsules, surface oil 18.12 x10-2 g/gmicrocapsules, microencapsulation efficiency 22.13%, and the estimated size between 1.05 to 12.90 μm. The chemicalprofile of pulp ginger oleoresin after the drying process was changed in this experiment.

Dalam penelitian ini dilakukanekstraksi oleoresin ampas jahe agar bisa dimanfaatkan lebih lanjut. Mikroenkapsulasi dilakukan untuk mempermudahpenanganan dan pengemasan produk. Penelitian ini bertujuan untuk mengetahui karakteristik mikrokapsul oleoresinampas jahe. Ekstraksi oleoresin ampas jahe menggunakan pelarut etanol 96% dengan tiga variasi rasio (b/v), yaitu1:4,1:5, dan 1:6. Mikroenkapsulasi dilakukan dengan teknik spray drying menggunakan penyalut maltodekstrin. Dalampenelitian ini dilakukan tiga variasi rasio oleoresin:maltodekstrin (1:50, 1:25, dan 1:16,7). Hasil penelitian menunjukkanbahwa efisiensi mikroenkapsulasi oleoresin ampas jahe tertinggi ada pada rasio 1:16,7. Mikrokapsul ini memiliki kadarair 6,37 % (db), αw 0,20,bulk density 0,46 g/ml, kelarutan 622,33 detik, total oil 42,62x10- 2g/g mikrokapsul, surface oil18,12 x10- 2g/g mikrokapsul, efisiensinya 22,13 %, dan estimasi ukuran antara 1,05-12,90 μm.
