N2  - Roselle (Hibiscus sabdariffa L.) have a lot of pharmacological activities which have
been widely reported both in vitro and in vivo and has been clinically tested. The
usage of the extract in powder form would be more practical and scalable as a raw
material and have advantages to facilitate its storage, distribution, standardization
of active substances and can improve its stability. The objective of this research is
to study the effect of maltodextrin addition for microcapsules formation related to
roselle flower calyx extract powder characterized by using spray drying method.
Research was carried out by made feed solution in ratio of 1: 1 (R1); 1: 2 (R2); and
1: 4 (R3) with a total solids content of 10%. Then, microencapsulated by spraydrying
method with 110-115C inlet and 99-104C outlet temperature, and flow rate
of 200 mL/hour. Microcapsules had characteristic morphological structures such
as spheric form. The average particle size decreased with the addition of
maltodextrin. The addition of maltodextrin can reduce the hygroscopicity of
extracts and increase solubility in water and moisture content. Spray drying
process in powder R2 give the encapsulation efficiency of 97.73% and product
recovery of 74.05%. All powder microcapsules have residual solvent <1%.
