RESUMO

ABSTRACT The bioactive compounds and in vitro antioxidant activity of jabuticaba fruits var. Pingo de mel were evaluated during their physiological development. The fruits were harvested ten days after anthesis until maturity, at intervals of four days between collections. The period between anthesis and maturity was 34 days. Higher phenolics levels, hydrolysed tannins, and antioxidant activity were observed in 10 days after anthesis, while vitamin C contents were higher throughout the ripening process. At the end of development (34 days), higher levels of vitamin C and lower hydrolysed tannin were observed. It is known that the lower the hydrolysed tannins, the better the sensory characteristics of the fruit, and considering the benefits of vitamin C, it is necessary to harvest the jabuticaba fruits var. Pingo de mel in 34 days after anthesis for better use of these compounds.
