Formulation and characterization of food-grade microemulsions as carriers of natural phenolic antioxidants

- Food-grade W/O microemulsions were developed as carriers of phenolic antioxidants.
- Swollen micelles with diameters smaller than 10 nm were detected by DLS measurements.
- Membrane dynamics were slightly affected by the encapsulation of the antioxidants.
- Cryo-TEM indicated the existence of entangled thread-like reversed micelles.
- Radical scavenging activity of the encapsulated antioxidants was evaluated by EPR.
