Construction of efficient ethylene removal and antibacterial cellulose paper-based packaging materials for avocado preservation.

Fruits are susceptible to ethylene ripening and microbial infestation, which can lead to spoilage and further significant economic losses. Thus, using functional preservation materials is an effective controlling technology to improve the post-harvest quality and extend the shelf life of fruits. Hence, a dual-function cellulose-based paper with exceptional antibacterial efficiency, favourable ethylene removal performance, improved mechanical and hydrophobic properties was prepared by covalently grafted antibacterial guanidine salt and surface-modified ethylene scavenger.
