Abstract
Solanum lycopersicum, a climacteric, and highly perishable commodity suffer significant postharvest loss along the supply chain. Staphylococcus aureus, Bacillus subtilis, Rhizopus stolonifer, and Aspergillus flavus are chief microorganisms responsible for the biological deterioration of tomatoes. The bioactive compounds present in the extracts of Azadirachta indica, Annona squamosa, and Carica papaya seeds effectively inhibit the growth of these spoilage-causing microorganisms. The research work has investigated the minimum inhibitory concentration of the target microorganisms and has incorporated the optimized concentration of the extracts into the biofilm. The designed biofilm was examined for various physical parameters and antimicrobial activity. The shelf-life of tomatoes packed with the bioactive film was extended to 13 days and the physical, physicochemical, and sensory parameters were found to be acceptable. Whereas the control sample was spoiled on day 5. Therefore, the packaging of tomatoes in the antimicrobial bioactive packaging material is a promising approach toward enhancing the shelf life.
