Galactomannan is a filmogenic polysaccharide suitable for edible coatings. The addition of nanoencapsulated active ingredients improves its antifungal activity. In this way, nanocomposite materials were developed based on galactomannan and anoencapsulated essential oil and polyphenols, extracted, respectively from Lippia grata and grape skin by-products. The size of chitosan nanoparticles increased after encapsulation, varying from 42 ± 24 to 295 ± 0 nm for polyphenols. Overall, the nanoparticle suspension was stable, with encapsulation efficiency close to 20% for the essential oil and 90% for polyphenols. Nanocomposite films were isolated by casting and characterized by scanning electron microscopy (SEM), infrared spectroscopy (FTIR), water vapour permeability, mechanical properties, release profile, and antifungal activity. By SEM, the films showed good nanoparticle dispersion in the matrix and improved mechanical properties compared to the non-added film. The sample based on essential oil showed good antifungal activity against Lasiodiplodia theobromae. Such properties make these films adequate for postharvest coating applications. |
