The aim of the present study was determine the O2 and CO2 levels for active modified atmosphere (MAP), besides evaluate 1-MCP effect about pulp softening delaying and skin browning during shelf life of persimmon fruit after storage in controlled atmosphere (CA) at the temperature -0.5°C. The experiment was carried in factorial arrangement (2x5) with three replications with eight fruit each. After storage plus shelf life was not found significant interaction on pulp softening, but fruit submitted to 1.0 kPa O2 during shelf life in MAP showed lower softening. However, for skin browning was observed significant interaction. The use of highly CO2 levels during storage at -0.5°C promotes higher skin browning in all the shelf life MAP conditions, except on fruit of control treatment, after six days of shelf life at 20°C. Partial pressure of 1.0 kPa O2 during MAP shelf life is the best condition for reduction pulp softening and skin browning of 'Fuyu' persimmon. Partial pressure of 6.0 kPa CO2 during storage in CA with 0.15 kPa O2, in cold storage (-0.5°C) keep higher skin browning during MAP shelf life. The use of 1-MCP no brink effect in low O2 level during MAP shelf life at 20°C.
