Enzymes activity, ascorbate peroxidase, catalase and superoxide dismutase, showed differences (p < 0.05) between the maturation stages, with exception of the ascorbate peroxidase of fruit skin that didn’t differ ( Table 3). The green stage presented the highest activity for all antioxidant enzymes, highlighting the enzymes on the pulp related to the skin. These results agree with the highest antioxidant activity in this stage. Behavior similar to X. americana was observed in fruits of acerola when studying the antioxidant metabolism of fruits, which found that the antioxidant activity, polyphenols, vitamin C and antioxidant enzymes showed higher values for the green fruits
