According to the abstract released by the Intellectual Property India: "An Anti-fungal food packaging film and a method of preparation The present invention discloses a sustainable anti-fungal food packaging material, comprising (i) Polyvinyl alcohol (3wt %), (ii) ZnO nanoparticles (20 wt%) and methanolic extract of lactic acid bacteria (1.25 wt %) and a method of preparation thereof; where the bacterial extract is prepared using the consortium of Lactiplantibacillus plantarum and Limosilactobacillus fermentum (LABCON) mixed at 1:1 ratio. The nanocomposite film showed antifungal activity against aflatoxigenic Aspergillus flavus MTCC 2798. The addition of methanolic lactic acid bacterial consortium and ZnO nanoparticle with Polyvinyl alcohol, enhanced mechanical and hydrodynamic properties of the film simultaneously offering microbial barrier property and easy biodegradability in soil. Overall, the claimed composition of film serves as an ideal packaging material for food articles."
