Effect of coating material on microencapsulated phenolic compounds extracted from agroindustrial ciriguela peel residue.

Background: Extract of ciriguela residue was microencapsulated by spray-drying and freeze-drying using maltodextrin (M), gum arabic (GA) and their mixture (50% M; 50% GA on dry basis) as encapsulating agents. Total phenolic compounds (TPC), antioxidant activity, physicochemical properties, profile of phenolic compounds by HPLC with diode-array detection and storage stability were evaluated.

Results: TPC content of powders ranged from 306.
