Abstract
Controlled atmospheres (CA) have been widely used in postharvest storage of fruits and vegetables. The gas compositions of common CA are consisted of O2, CO2 and N2, postharvest storage condition with gas combination of O2 and CO2 was rarely studied. In this research, the effects of CA with different CO2/O2 levels, i.e. 70% O2 + 30 % CO2, 60 % O2 + 40 % CO2, 50 % O2 + 50 % CO2, 40 % O2 + 60 % CO2, 30 % O2 + 70 % CO2, and air (control) on the storage life and properties of broccoli during storage were investigated at different temperatures including 0, 10 and 20 °C. Results showed that the storage period of air treatments at 0, 10 and 20 °C was 21, 12, and 4d. Treatments with 60 % O2 + 40 % CO2 at 0 °C, 50 % O2 + 50 % CO2 at 10 °C, and 40 % O2 + 60 % CO2 at 20 °C maximum inhibited respiration rate and ethylene production, maintain chlorophyll and ascorbic acid content, reduced the accumulation of acetaldehyde and ethanol, and extended the storage life of broccoli florets to 49, 31, and 14d compared to 21 d at 0 °C, 12 d at 10 °C and 4 d at 20 °C in air-treated broccoli. These results indicated that an appropriate CA with O2/CO2 might be a potential strategy for postharvest storage of broccoli heads, and the appropriate proportion of O2 and CO2 might vary with different temperature.
