Abstract The changes in concentration of vitamin C, enzymatic and antioxidant activity during the ripening of two soursop selections (G1 and G2) at room temperature (22 ºC) and refrigeration (15 ºC) with an HR 85% were evaluated. The content of soluble protein, the activity of catalase (CAT), superoxide dismutase (SOD), peroxidase (POD), the concentration of vitamin C, as well as the antioxidant activity was evaluated by DPPH, ABTS and FRAP methods. The initial soluble protein concentration of the G1 and G2 selections diminished at 22 and 15 °C during ripening. Fruits stored at 22 °C showed the highest CAT activity. The maximum activity of SOD was recorded on the sixth and fourth day in fruits stored at 22 and 15 ºC, respectively. Fruits stored at 22 °C recorded the highest amount of vitamin C. Fruits stored at 22 and 15 ºC showed the highest antioxidant activity on the fourth day. The fruits stored at 15 ºC was able to increase the shelf life up to 8 days without affecting the ripening process. Therefore, the enzymatic and antioxidant activity has an important role in the possible alteration that the fruit might suffer during its fruit ripening.
