Fabrication of pectin/agar blended functional film: Effect of reinforcement of melanin nanoparticles and grapefruit seed extract

Pectin/agar blended multifunctional composite films were prepared by reinforcing with melanin nanoparticles (MNP) and grapefruit seed extract (GSE). The physical properties of composite films made by mixing pectin and agar have been improved. The MNP and GSE were well dispersed in the pectin/agar blend film. The addition of MNP and GSE significantly increased the composite film's UV-blocking property, with some sacrificing transparency. The...
