Daftar Isi:
- Roselle (Hibiscus sabdariffa L.) or Red tea is herbal agricultural products. Rosella flower has medicinal properties and characteristics more organic so it does not use chemicals. This rosella flowers contain essential for the body include: vitamin C, A, delphinidin 3-monoglukosida, sianidin 3-monoglukosida, delphinidin and phenolic compounds. However, this has the disadvantage of flowers quickly decay after being picked so it must be in the process within 2 days and the poor drainage. Compounds are easily damaged it contains flavonoids gossypetine, hibiscetine, and sabdaretine and previously identified as a major pigment phniphylline. The risk of physical damage and chemical compounds on the rosella flower so unthinkable to try to protect a lost and damaged compound with the microencapsulation process. The objectives of this research was to understand the effect of microencapsulation process concerned to physical, chemical, characteristic of final product. Production of Hibiscus sabdariffa L. extract used substance and aquadest ratio 1:4. This extract was added with maltodextrin in variation 22,5 gr (1:0,5), 45 gr (1:1), 67,5 gr (1:1,5), 90 gr (1:2) and dried with spray dryer at temperature 100°C inlet and 70°C outlet. Hibiscus sabdariffa L. extract with 22,5 gr maltodextrin added had the highest yield. Adding 22,5 gr of maltodextrin had obvious effect for increasing solid content in the extract. Microencapsulation by spray drying had obvious effect in order to decreased water content, the particle size became smaller, encapsulation efficiency ascorbic acid, encapsulation efficiency phenolic and the increased of the solubility in final product. Hibiscus sabdariffa L. powder encapsulation of variation 1:0,5 until 1:2 had 44,79%, 44,35% 37%, and 43,57% ascorbic acid efficiency in 100 gram. Hibiscus sabdariffa L. powder encapsulation of variation 1:0,5 until 1:2 had 41,61%, 39,17%, 30,58%, and 26,96% phenolic eficiency in 100 gram.
