Development of bionanocomposite film based on chia seed mucilage incorporated with ZnO nanoparticles and their application for preserving fresh rainbow trout (Oncorhynchus mykiss) fillets

In this study, chia seed mucilage was used as the film-forming matrix. The antimicrobial and antioxidant activity of chia seed mucilage films has been attributed to Zn0-NPs. The addition of different concentrations of Zn0-NP (0.25%, 0.5% and 1%) to the chia seed mucilage film matrix significantly affected the mechanical, thermal, antioxidant and antimicrobial properties. It also improved the storage quality of rainbow trout fillets during storage at 4˚C for 18 days (p
