This study investigated the antifungal features of sodium alginate (Alg) 1% combined with lemongrass essential oil (LGO) 0.25%, 0.5% and 0.75% as a Pickering emulsion coating to control Penicillium digitatum and P. italicum, identified as citrus fruit pathogens. Cellulose nanofibers 0.24%, 42.55 ± 9.34 nm, were selected as a stabiliser. Confocal laser scanning microscopy and Fourier-transform infrared spectroscopy were used to analyse the droplet size and morphology and chemical interaction of emulsified coating, respectively. The effective dosage of lemongrass oil (0.75%) may enhance the antifungal action confirmed with a series of in vitro tests on spore germination by 88.28% (P. digitatum) and 91.94% (P. italicum), germ tube elongation by 89.28% (P. digitatum) and 90.13% (P. italicum) and membrane integrity by 41.67% (P. digitatum) and 63% (P. italicum). Additionally, the incorporation of LGO Pickering emulsion improved the beneficial properties of Alg-based coating film, including light transmission at UV and visible light wavelengths and hydrophobicity. Scanning electron microscopy was performed to evaluate the interior microstructure of the coating film. Pickering emulsion-based coatings described in this study may have potential applications for active packaging, particularly for citrus fruit commodities.
