Abstract
The research of microcapsule efficiency of ethanol extract of sepal flower (Hibiscus sabdariffa Linn) coated crude carrageenan has been done. The aim of research is to determine the highest eficiency microencapsulation based on the ratio of ethanol extract of the sepal flower toward seaweed crude carrageenan (Eucheuma cotonii ) as coating substance. The microencapsulation was carried out by using freeze drying technique. This encapsulation may preserve the active compound of ethanol extract. Ratio of ethanol extract of the sepal flower toward seaweed crude carrageenan were set at 1:3 1:4 1:5 1:6 dan 1:7 (w/w). The result of research obtained that the highest eficiency ratio is at 1:7 with percentage of 86,01%.
