Changes in ethylene production, carbohydrase activity and antioxidant status in pepper fruits during ripening

► Pepper Kulai is climacteric fruit with a peak ethylene production. ► β-Galactosidase is likely to play a role in cell wall modification during ripening. ► Comprehensive study on profile antioxidant during ripening of pepper Kulai. ► Oxidative stress increased along the ripening process. ► Antioxidant status is elevated at the same time, suggesting a defensive response.
