Papaya (Carica papaya L.) is one of the most cultivated fruit species in the world, with Brazil being the second largest producer of this crop in the world, however it is still necessary to develop techniques in post-harvest management aimed at improving the quality of the fruit. Papaya has a high moisture content and respiratory rate, being easily damaged, and may suffer losses directly in the fruit due to pulp degradation and economic losses due to lack of consumption in a timely manner. The objective of this work was to evaluate the effect of different concentrations of a homogeneous solution of citrus essential oil containing D-Limonene on papaya disinfestation in the post harvest process, on extending shelf life and its effect on fruit quality. An in loco experiment was carried out with 'THB' papaya fruits, carried out in a packing house at Fazenda Caliman Agrícola AS. The experimental design was in randomized blocks with six treatments, consisting of four doses of D-Limonene (3000, 4000, 5000, 6000 ppm), a negative control treatment (water) and a conventional standard farm treatment (20 ppm of chlorine), each with four replicates. The fruits were exposed to two tests: fruit storage at 16 °C + 2 °C with evaluations after 8 and 11 days of storage, in which the physicochemical quality was evaluated; in the second trial, the fruits were stored at a temperature of 25°C and evaluated after 7 days of storage to evaluate the incidence of diseases. The results indicated that there was no statistically significant interaction between D-Limonene doses and storage time, for any of the characteristics evaluated. The incidence of diseases was low and was not related to the treatments, a result linked to the high health of the fruits studied. The physicochemical quality of the fruits was not affected by the treatments. It is concluded that the concentrations of D-limonene can be used in papaya post-harvest as they do not affect the quality of the fruit, however, to prove the sanitizing effect, basic research studies should be conducted, with inoculum control.
