Physicochemical, antioxidant, and enzyme inhibitory properties of Bignay (Antidesma bunius L. Spreng) and Duhat (Syzygium cumini L.) extracts microencapsulated with β-cyclodextrin

Seasonal tropical fruits with health-promoting properties are commonly dehydrated to preserve their bioactive potential. Despite the commercial and industrial appeal of spray drying, the significant capital outlay may deter small-scale applications associated with small volumes of seasonal fruits. In this study, inclusion complexation using β- cyclodextrin (bCD) was applied to ethanolic extracts of two common seasonal fruits, duhat and bignay, and the resulting powders were characterized using spectrophotometric, electron microscopy, colourimetric, and gravimetric methods. Electron microscopy images of microcapsules and changes in FTIR spectra indicate successful encapsulation. Despite having different concentrations of monomeric anthocyanins, phenolic contents and radical scavenging activities, the inclusion complexes possess equal encapsulation efficiencies and retention of bioactive components with antioxidant and enzyme inhibitory activities. The results of this study can be used to design small-scale encapsulation strategies for indigenous, seasonal fruits

Abstract

Seasonal tropical fruits with health-promoting properties are commonly dehydrated to preserve their bioactive potential. Despite the commercial and industrial appeal of spray drying, the significant capital outlay may deter small-scale applications associated with small volumes of seasonal fruits. In this study, inclusion complexation using β- cyclodextrin (bCD) was applied to ethanolic extracts of two common seasonal fruits, duhat and bignay, and the resulting powders were characterized using spectrophotometric, electron microscopy, colourimetric, and gravimetric methods. Electron microscopy images of microcapsules and changes in FTIR spectra indicate successful encapsulation. Despite having different concentrations of monomeric anthocyanins, phenolic contents and radical scavenging activities, the inclusion complexes possess equal encapsulation efficiencies and retention of bioactive components with antioxidant and enzyme inhibitory activities. The results of this study can be used to design small-scale encapsulation strategies for indigenous, seasonal fruits
