C.  aPreservation of quality and bioactive compounds in mangoes using chitosan-graphene-oxide-based biodegradable packaging.h[electronic resource]  c2023  aMango is a climacteric fruit that requires efficient postharvest technologies to maintain quality during storage and transportation. This study aimed to investigate the effect of biodegradable packaging from chitosan (CS) incorporated with graphene oxide (GO) on the quality, bioactive compounds and antioxidant activity of cold-stored ?Tommy Atkins? mangoes. Mangoes harvested at physiological maturity were stored without packaging or in CS, CS-GO or non-biodegradable polyethylene (PE) packaging at 12.0 ◦C and 89% relative humidity for 42 days. The results show that GO improved the water barrier and mechanical properties of CS packaging. All packaging delayed fruit ripening by reducing the respiration rate, mass loss, softening and changes in color, soluble solids, titratable acidity and beta-carotene content, also preserving the mangoes? visual appearance. In addition, all packaging maintained higher ascorbic acid, yellow flavonoid, phenolic compounds and antioxidant activity levels in the fruit, compared to non-packed ones. Chitosan packaging is a promising, eco-friendly alternative for the preservation of quality, bioactive compounds and antioxidant activity of cold-stored ?Tommy Atkins? mangoes, extending their postharvest life by at least 14 days.  aBiopolymers  aCarotenoids  aMangoes  aNanoparticles  aPackaging  aPhenolic compounds  aPostharvest physiology  aPostharvest technology  aPostharvest treatment  aShelf life  aArmazenamento  aCarotenóide  aComposto Fenólico  aEmbalagem  aManga  aMangifera Indica  aPós-Colheita  aAmadurecimento de frutos  aBiopolímeros  aCompostos bioativos em mangas  aEmbalagem de quitosana  aEmbalagens biodegradáveis  aNanopartículas  aÓxido de grafeno  aÓxido quitosana  aQualidade pós-colheita  aSubstâncias biodegradáveis  aTommy Atkins1 aFREITAS, S.
