The objective of this work was to determine quality, bioactive content and metabolism of vitamin C and phenolic compounds during the development of acerola BRS 238 (Frutacor). Fruits were harvested at five different stages of maturation and evaluated for physical-chemical and chemical quality characteristics, as well as for the metabolism of vitamin C and polyphenols variables. During development, there was an increase in SS/AT ratio, a decrease in chlorophyll content, increase in carotenoids content, and a decline in vitamin C and polyphenols content, alhhtough of yellow flavonoids and anthocyanins content increased. The enzyme activity of vitamin C metabolism, ascorbate oxide (AO) and ascorbate peroxidase (APX) decreased with ripening, while for phenolic metabolism, the activity of phenylalanine ammonia lyase (PAL) increased and polyphenoloxidase (PPO) decreased. It can be concluded that the fruits of aceroleira BRS 238 had a high content of bioactive compounds. For industrial extraction of bioactive compounds, fruits must be harvested at the initial stages, while for fresh consumption, they must be harvested in the final stages of development.
