This study evaluated the effect of the native cassava starch solution (Manihot esculenta crantz) and commercial wax application on the firmness, rate of breathing, degrees brix and tomato pH (Lycopersicom esculentum mill) to room temperature, through an experimental design completely at random with 3 replications and 3 repetitions, the results were submitted to a variance analysis with a probability of 95%; the significantly different average values were compared using the test of Dunnet, for a probability of 95%. There were no significant differences in the evolution of the rate of breathing, degrees brix and titleable acidity (Pf of 0,26, 0,48 and 0,28 respectively) whereas if there were it, in the firmness (Pf of 0,045), where the tomatoes covered with commercial wax showed a greater firmness and a lower rate of breathing that the fruits covered with the starch solution and the witness.
