Bio-nanocomposite films loaded with lemon leaf extract for bio packaging application

Objective: The present article details the preparation and characterization of bio-nanocomposite films loaded with nanoclays and chitosan which are the catalysts for retaining the fresh quality of flowers, fruits, and vegetables and extending their shelf life under packed with this film. The development of new packaging films is currently an emerging field for the consumers and edible goods trading industries. Hence, novel bio packaging films with a unique combination is essential to ensure optimum characteris-tics for the bio packaging films, thereby obviating synthetic plastics.Methods: Synthesis and characterization of the formulated blends of carboxymethylcellulose incorpo-rated with chitosan, nanoclays, epoxy, and polyethylene glycol with the addition of lemon leaf extract (LLE) and analysis of their antibacterial activity.Result: The results indicate that when the jasmine flower buds were packed with the synthesized film, retain their buddy state for a minimum of 5 days at room temperature, freshness, and fragrance. Conclusion: Hence, the nano-bio packaging film will ensure the transportation of daily harvested flowers, fruits, and vegetables from farms to firms, stores, and homes.(c) 2022 The Author(s).

Automated summary

This article describes the preparation and characterization of bio-nanocomposite films loaded with nanoclays and chitosan, which act as catalysts for maintaining the freshness and extending the shelf life of flowers, fruits, and vegetables. The results show that jasmine flower buds packed with the synthesized film can retain their freshness and fragrance for at least 5 days at room temperature.
