SUMMARY:

The tomato fruit (Solanum lycopersicum L.) is versatile, being consumed fresh or processed, but has a limited shelf life. Therefore, the use of natural substances with antimicrobial and antifungal properties are important for use as post-harvest treatment. Thus, the objective was to evaluate the effects of copaiba and propolis essential oils on post-harvest characteristics and physicochemical parameters in tomato fruit variety TY-16. The fruits were immersed in the prepared solutions of essential oils with the exception of the control treatment, in which they were only washed with the chlorinated solution. A completely randomized design and factorial scheme (2 x 5) were used. Data were determined at 0, 5, 10 and 15 days and subjected to analysis of variance by the F Test and the use of Dunnett's test to compare each concentration versus control, at a 5% probability level (p<0.05) . Data were also subjected to regression analysis to determine the best dose. The statistical program used was GENES. There was no significant difference between the concentration levels of green propolis and, for red propolis, there was a significant difference only for Brix, highlighting the treatments with doses of 2 and 4%. The most interesting effects were those obtained with the treatments of fruits with copaiba. The distilled copaiba presented better results at 5% and 7% of inclusion and the balsamic copaiba as the inclusion level increases, the mass loss and fruit firmness decreases. The estimate of the most efficient doses for post-harvest treatment, from the regression equations, would be 24.45% for the distilled extract of copaiba and 20.98% for the balsamic extract of copaiba.
