The present work had the objective to evaluate the effect of the temperature and CO2 in controlled atmosphere storage on the quality of 'Quioto' persimmons. Temperatures of -1,0 and -0,5ºC and CO2 partial pressures of 0, 5 and 10kPa were evaluated, and treatments were organized in a bifatorial design. The fruits were evaluated after 3 months of storage more 3 days of shelf-life (18-20ºC). There was only significant effect of the temperature on pulp firmness. The Fruits stored at -1,0ºC showed higher pulp firmness than fruits at -0,5ºC. Different CO2 partial pressures did not have influence on the weight loss and pulp firmness. A negative lineal response was observed for decay in relation to CO2 partial pressures, which incidence was very high. The other parameters had a quadratic response. In CA storage with CO2 value between 5 and 10kPa the fruits had a lower skin browning and more yellow and red coloration. The CO2 between 5 and 10kPa presented the best results and added to temperature of -1,0ºC were the best storage condition, however, the storage period should be shorter than 3 months at these condition, due to high losses with decay.
