Total phenolic content and antioxidant activity of spray-dried microcapsules propolis from Tetragonula species
The objective of this study was to determine the total phenolic content (TPC) and antioxidant
activity (AA) of propolis microcapsules from Tetragonula spp. A microplate reader was used
to determine TPC and AA. Smooth propolis extract with the highest TPC and AA was used
as core material for microencapsulation with maltodextrin and gum arabic as coating
materials, prepared by using the spray-drying method. Scanning electron microscopy was
used to analyze the morphologies of microcapsules. The spray-dried propolis (SDP) …
