Microencapsulation of Spray Dried Resveratrol Emulsion Using Sodium Caseinate-Maltodextrin Conjugate

Abstract

Resveratrol (RSV) has been linked to a wide range of biological activities, particularly anti-oxidant, antibacterial, anti-inflammatory, and anti-carcinogenic characteristics. However, because of limitations such as chemical deterioration happen during storage (UV light and oxygen), low aqueous solubility, and oral bioavailability, this study used an emulsion-based system with sodium casein-ate-maltodextrin (SC-MD) conjugate by Maillard reaction as coating materials to increase RSV aqueous solubility. The characterization of microencapsulated RSV emulsion spray-dried powder was done. Conjugate and casein microen-capsulated RSV spray-dried powder showed 76.41 and 54.61% encapsulation efficiency, 7 and 6.5 mm of average diameter, respectively. The composition of spray-dried microencapsulated RSV emulsion with conjugate was found to be 14.2% moisture, 85.78% total solids, 38.20% protein, 7.81% fat, 0.83% ash, and 38.2% carbohydrate. As a result, microencapsulated RSV spray-dried powder with a SC-MD conjugate improves the stability of RSV for providing the poly-phenolic health advantages of RSV.
