Abstract/Description: | Spice oleoresins exhibit sensitivity to light, heat and oxygen and have lower shelf life if not stored properly. The technique of microencapsulation provides a better stability and in addition controls the release of bioactive compounds. Paprika oleoresin with 1,00,000 CU was encapsulated at three concentrations as 5, 10 and 15 per cent based on carrier. Quality characteristics of the microcapsules revealed that the storage life of Paprika oleoresin was maximized by encapsulating Paprika oleoresin (5- 15%) in miniature sealed capsules with a matrix material (Gum Arabic) in order to protect destructive changes and also to convert it into a free flowing powder. Scanning Electron Microscopy study showed that microcapsules obtained from oleoresin encapsulated with 10 and 15 per cent, had superficial indentations and dents similar to honey comb structure, as well as lesser cracks and breakages on the surface, which ensured greater protection to the core material. Of the three concentrations of microencapsulated paprika oleoresin (MPO), oleoresin encapsulated at 10 per cent had better scavenging activity. HPTLC analysis confirmed the presence of major phytochemicals namely alkaloids, flavonoids and carotenoids in the microencapsulated paprika oleoresin |
