The possibility of commercialization of Moro blood
oranges in tropical countries such as Brazil was evaluated to verify whether
post-harvest management through storage at low temperatures for a period of 60
days can improve the bioactive properties and quality parameters. Moro blood
oranges cultivated in Brazil did not contain significant amounts of
anthocyanins at the time of harvesting, but these compounds were activatedby post-harvest management through storage at low
temperatures (4°C and 8°C) for a period of 60 days. The emergence of the anthocyanins
in the juices occurred within a few weeks of storage, but the maximum levels
were attained after 60 days and at the temperature of 8°C. Cold storage positively influenced other
bioactive compounds such as total phenolic compounds, individual phenolic
compounds, β-carotene and the antioxidant activity determined by
the sequestration of DPPH free radicals. It did not influence the vitamin C
content. In addition, storage significantly altered the color, total
