摘要
为探究冰温气调状态下微环境波动(即温度波动、气体环境波动、温度气调双波动)后蓝莓品质的变化规律,以“蓝丰”蓝莓为试材,预冷处理后分别放入不同的冰温(-2℃和-1℃)气调(CO_(2):10%~14%;O_(2):6%~9%)环境贮藏7 d,分析蓝莓果实的最佳贮藏环境状态。在此基础上,设计3组微环境波动试验,即温度波动、气调波动、温度和气调双波动,分别波动1~6 d,每次波动结束后采取相应措施进行贮藏,测定1~7 d各试验组蓝莓果实的硬度、内聚性、可滴定酸含量、花青素含量、丙二醛含量。结果表明,试验组的保鲜效果更好。微环境波动试验中,蓝莓的最佳贮藏时间1 d。“蓝丰”蓝莓果实的最佳冰温气调环境为-1℃(CO_(2):10%~12%;O_(2):6%~9%),蓝莓果实品质与波动时长呈负相关,采用降温/降氧/双降手段虽有一定效果,但不能使蓝莓果实品质恢复至冰温气调组的最佳状态。
In order to explore the changes of blueberry quality after microenvironment fluctuations(i.e.,temperature fluctuations,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(CO_(2):10%-14%;O_(2):6%-9%)were stored in the environment for 7 days,and the optimal environmental 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,titrable 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 microenvironment 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℃(CO_(2):10%-12%,O_(2):6%-9%),and there was a negative correlation between blueberry fruit quality and fluctuation time.Although cooling/oxygen lowering/double descending methods had certain effects,the blueberry fruit quality could not be restored to the best state in the ice temperature and air conditioning group.
