Abstract
Fresh fruits are susceptible to microbial and insect infestation, and proper packaging is critical in reducing wastage. Essential oils are promising ingredients for food-active packaging, but their high volatility limits direct application. In this study, the inclusion complex (IC) of β-cyclodextrin/Litsea cubeba essential oil was prepared and incorporated into polylactic acid nanofiber films to achieve the dual functions of antifungal and anti-Drosophila. The successful synthesis of IC was confirmed by XRD and DSC. The films were characterized by SEM, FT-IR, WCA, TGA, and mechanical properties, with good gas permeability and release profile. It showed good inhibition effects of Aspergillus niger, Curvularia lunata growth, and the egg hatching, third-instar larval growth of Drosophila melanogaster. In the actual preservation of Chinese bayberry, the shelf life was extended by 4 days. This research opened up new perspectives for the development of dual-functional food packaging that is resistant to microorganisms and insects.
