DEVELOPMENT AND CHARACTERIZATION OF MICROENCAPSULATES OF RED PROPOLIS FROM ALAGOAS BY THE ION GELIFICATION METHOD
Red Propolis, alginate, thermic analyzes, chromatography, beads
Propolis is a natural product that presents a complex mixture, formed by a resinous and balsamic material collected by bees from branches, flowers, pollen, buds and tree exudates. In Brazilian territory, red propolis can be found in several parts of the coast, mainly in mangrove areas. Botanically originating from Dalbergia ecastaphyllum, popularly known as "bugio's tail". Red Propolis of Alagoas stands out for having a large amount of flavonoids, phenolic compounds and some other exclusive compounds. These bioactive compounds have several biological activities, such as anti-inflammatory, healing, antioxidant, antimicrobial, as well as antiviral, antifungal, anticancer, immunomodulatory potential, among others. In this study, we developed microencapsulates (beads) containing crude extract of red propolis, from the ionic gelation method using sodium alginate and calcium chloride, in different concentrations. Subsequently, the generated beads were characterized by scanning electron microscopy (SEM), attenuated total reflectance (ATR), thermogravimetry (Tg), differential scanning calorimetry (DSC), phenolic compounds content, and high-performance liquid chromatography (HPLC). Finally, it is expected that this work can generate an interesting formulation containing red propolis, which can be improved in the future.
