Roselle is a very useful plant. Widely used as traditional medicine, its
calyx functions as antioxidant, antiseptic, diuretic, and anticholesterol. This
research is aimed at knowing the concentrate of povidone toward the condition of
a good quality of granule, taste reaction, and the detection of content of flavonoid
in the instant granule of the roselle extract. The fresh calyx roselle was pounded
with mixer and then the obtained essence was steamed to lose the water content,
until thick extract was derived. The instant granule of rosella juice was
formulated with wet granulation method in 3 formulas which is based on
differrent concentrate of povidone, they are F I (1%), F II (3%), F III (5%). The
test were done to the instant granule from the extract Hibiscus sabdariffa for its
granule physical test and taste reaction test. The result of the test of physical
instant granule showed that F I meet the requirement of good granule. For flow
rate test (8,29  0,38 second), point of quit test (39,11  0,790), moisture content
test with %MC (2,99  0,046), and for test distribution of the size of particle with
microscopis method (692,1797 μm). The result of the test of taste reaction showed
that the extract of instant granule can be accept by the respodent.
