Freeze and spray drying of Scaptotrigona bipunctata (Lepeletier, 1836) pollen - development and physicochemical characterization

This study was carried out to evaluate human consumption of the pollen of Scaptotrigona bipunctata colonies stored in pots; it was lyophilized and spray-dried in arrays of arabic gum and hydrolyzed collagen which have been widely applied to get products with best technological features and highest biological activity. After the samples were prepared they were evaluated by physicochemical analysis, and the data were compared. S. bipunctata pollen lyophilized had product with higher antiradical activity than the pollen dried using spray dryer which only quantified the antioxidant activity of the antioxidant compound that was encapsulated and stabilized in the solid matrix material. Key words: Biological activity, encapsulated pollen, lyophilized pollen, phenolic profile, stingless bees.
