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 phe- nolic compounds, antioxidant capacity and microbial growth in mango cubes. Analysis of variance ANOVA was performed (p ≤ 0.05) to estimate significant differ- ences between treatments, Tukey-Kramer was the mean test used for comparison (p ≤ 0.05) performed with the Number Cruncher Statistical Systems [21].
