The experimental design was completely randomized blocks, where the factors were the treatment (0 and 25 mg/mL of ethanolic seed extract) and the time, which was blocked to see the effect of the treatment on the phenolic compounds, antioxidant capacity and microbial growth in mango cubes. Analysis of variance ANOVA was performed (p ≤ 0.05) to estimate significant differences between treatments, Tukey Kramer was the mean test used for comparison (p ≤ 0.05) performed with the Number Cruncher Statistical Systems [21].
