Conteúdo: | This study describes the deterioration rates of ?Imperial Gala? and ?Fuji Suprema? apples fruit along 30 days after controlled atmosphere storage (ACAS). It was simulated handling periods of 11 days at packinghouse (PH), 7 days at shipping and distribution center (S&DC) and 12 days at retail and consumer home (R&C). Apple fruit harvested from six commercial orchards in Brazil were stored in commercial CA rooms at 0.7°C for 17 to 29 weeks. At the pre-shipping period (PH), fruit was kept at 10°C between the 2nd and 4th day ACAS simulating the sorting and packaging periods and then at 0.5°C between the 5th and 11th day ACAS, simulating storage of sorted or packed apple. The treatments were four temperature regimes applied from 12th to 30th day ACAS: 1) continuously at 0.5°C; 2) continuously at 22°C; 3) 0.5°C from 12th to 18th day (S&DC) and 22°C from 19th to 30th day (R&C); 4) 22°C from 12th to 18th day and 0.5°C from 19th to 30th day. Fruit deterioration was affected by post-storage temperature, cultivar, and orchard-length of CA storage factor. Fungal decay was the main disorder developed ACAS period and the limiting factor of the marketing period. The maximum incidence of decayed fruit was 7 and 25% for ?Imperial Gala? and 10 and 34% for ?Fuji Suprema? kept continuously at 0.5 and 22°C, respectively. Low temperature from 12th to 18th day was more effective than low temperature from 19th to 30th day to delay the appearance of fungal decay symptoms and to increase the marketing period. However, low temperatures from 19th to 30th day resulted in a lower incidence of decayed fruit on 30th day ACAS than low temperatures from 12th to 18th day. Low temperature following CA storage also delayed the development of flesh browning and loss of firmness in ?Galas? apples and shrivel in both cultivars.
