Encapsulated Indian gooseberry (Phyllanthus emblica L.) powder was prepared using different drying techniques (freeze dry and spray dry), and different wall materials consisting of a combination of maltodextrin and hydrocolloids or maltodextin only. An encapsulation efficiency, moisture content, solubility, color, morphology, and wall-materials released during in vitro digestion were studied. The 10MalGA, using the spray drying techniques showed higher encapsulation efficiency than that of freeze drying techniques and other samples. The spray dried samples powder were lighter than that of freeze dried samples powder. The high %EE and low solubility of MalGe-FD powder might be due to the rougher surface and highly porous investigated from SEM. The combination of maltodextrin and hydrocolloids displayed less susceptibility to amylolytic enzymes digestion compared to the pure maltodextrin as a wall-materials. Thus, the properties of encapsulated extract powder was depending on wall material, total solids in the system, and drying technique.
