Effect of Microenvironment Fluctuation on the Quality of Blueberry during Ice-temperature Controlled Atmosphere Storage
In order to explore the changes of blueberry quality after microenvironment fluctuations(i.e.,temperature fluc-tuations,gas environment fluctuations,and temperature and gas fluctuations)under the state of ice temperature and gas regulation,Lanfeng blueberry was taken as the test material and pre-cooled at different ice temperature(-2℃ and-1 ℃)for air conditioning(CO2:10％-14％;O2:6％-9％)were stored in the environment for 7 days,and the optimal en-vironmental state of blueberry fruit was analyzed.On this basis,three groups of microenvironment fluctuation tests were designed,namely,temperature fluctuation,air fluctuation,temperature and air fluctuation,which fluctuated for 1aq to 6 days,respectively.After each fluctuation,corresponding measures were taken for storage.The hardness,cohesion,titra-ble acid content,anthocyanin content and malonaldehyde content of blueberry fruits in each experimental group were measured for 1 to 7 days.The results showed that the fresh-keeping effect of experimental group was better.In the mi-croenvironment fluctuation test,the optimal storage time of blueberry was 1 day.The optimal ice temperature and air conditioning environment of Lanfeng blueberry fruit was-1 ℃(CO2:10％-12％,O2:6％-9％),and there was a negative correlation between blueberry fruit quality and fluctuation time.Although cooling/oxygen lowering/double descending meth-ods had certain effects,the blueberry fruit quality could not be restored to the best state in the ice temperature and air conditioning group.
