Method & Evidence

AimTo investigate the physicochemical properties, microencapsulation, and application of lemon verbena essential oil in starch-based bioplastics for enhanced functionality and sustainability.
MethodExperimental research involving chemical characterization, microencapsulation via spray drying, and material testing.
ProcedureLemon verbena essential oil was characterized for its chemical composition and bioactivity. It was then microencapsulated using dextrin and soy lecithin via spray drying. The resulting microparticles were incorporated into starch-based bioplastic films, and the films were tested for visual changes, flexibility, UV barrier properties, water vapor permeability, and mechanical integrity. Microstructural analysis using SEM and molecular interactions using FT-IR were also performed.
