Being a highly perishable fruit, it is susceptible to mechanical damage and the attack of pathogenic microorganisms that reduce the quality of the fruit and limit its commercialization at a national and international level, which has caused great post-harvest losses. Thus, the purpose of this research was to evaluate the application of sodium bicarbonate as an antifungal treatment for the control of anthracnose in papaya (Carica papaya L.) in the postharvest period. In the fruits, the microorganism was inoculated by wound and the treatments were applied: study sodium bicarbonate at different concentrations (1, 2 and 3%), fungicide treatment (prochloraz) and control fruits (without any treatment) and it was stored during 35 days, 28 days at 13 ± 1°C and 90 ± 5% RH and 7 days at room temperature (20 ± 2°C). To evaluate the antifungal effect of the treatments, daily measurements of the severity of the rot were made and the physical-chemical parameters of the fruits under study were evaluated at each exit. In addition, semi-trained panelists evaluated the sensory quality. The alternative treatment that had the greatest antifungal effect in controlling anthracnose was the application of 2% sodium bicarbonate, since it ended the growth of Colletotrichum sp., as well as it did not affect the physicochemical quality of the fruit and presented a better visual appearance compared to control fruits. |
