description	Papaya is a highly perishable climacteric fruit. Anthracnose, a disease provoked by fungus, is one of the main causes of postharvest losses. The activity of plant extracts has allowed the inhibition of the development of microorganisms; in particular, the antifungal activity of essential oils has been reported. The aim of this research was to evaluate the effect of a biodegradable antifungal coating based on chitosan with citrus essential oil in the physicochemical and physiological properties and the antifungal activity of postharvest papaya (Carica papaya L.). The coating was prepared with chitosan, glycerol, acetic acid, essential oil of Citrus reticulata (0.5 %, 1.0 % and 1.5 %) and Tween® 80. The solution was applied with a brush to the epidermis of the postharvest papaya fruits and stored at room temperature (24 °C ± 2 °C) for 10 d. The variables evaluated in the fruits were color, pH, °Brix, firmness, weight loss, production of CO2 and ethylene and anthracnose damage. An analysis of variance (ANOVA) was performed under a completely randomized design and a comparison of Tukey means (P < 0.05). The coating applied delayed the color change of the epidermis of the papaya fruits, these maintained the high firmness values with respect to the control fruits. The changes were associated with the modification of the respiration rate and ethylene production of the coated fruits. The chitosan matrix containing essential oils used as a coating significantly improved shelf life of papaya and decreased anthracnose damage by 80 %.

La papaya es una fruta climatérica altamente perecedera. La antracnosis, enfermedad provocada por hongos, es una de las principales causas de pérdida poscosecha. La actividad de extractos vegetales ha permitido la inhibición del desarrollo de microorganismos, en particular se ha reportado la actividad antifúngica de aceites esenciales. El objetivo de la presente investigación fue evaluar el efecto de un recubrimiento biodegradable a base de quitosano con aceite esencial de cítricos, aplicado en etapa poscosecha, en las propiedades físicoquímicas, fisiológicas e inhibición del crecimiento del hongo Colletotrichum gloeosporioides en frutos de papaya (Carica papaya L.). El recubrimiento se preparó con quitosano, glicerol, ácido acético, aceite esencial de Citrus reticulata (0.5 %, 1.0 % y 1.5 %) y Tween® 80. La solución se aplicó con una brocha en la epidermis de los frutos de papaya y se almacenaron a temperatura ambiente (24 °C ± 2 °C) por 10 d, junto con los frutos testigo. Las variables evaluadas en los frutos fueron color, pH, sólidos solubles totales (SST), firmeza, pérdida de peso, producción de CO2, de etileno y daño por antracnosis. Se utilizó un modelo estadístico completamente al azar. Los datos se sometieron al análisis de varianza (ANOVA) y comparación de medias por la prueba de Tukey (P < 0.05). El recubrimiento aplicado retrasó el cambio de color de la epidermis de los frutos de papaya, la pérdida de peso, firmeza y SST respecto a los frutos testigo. Los cambios estuvieron asociados a la modificación de la tasa de respiración y de producción de etileno de los frutos con recubrimiento. La matriz del quitosano conteniendo aceites esenciales, usada como recubrimiento, mejoró significativamente la vida de anaquel de la papaya y disminuyó más del 80 % el daño por antracnosis.
