摘  要：
为研究O_2/CO_2气调环境下CO_2对西兰花叶绿素降解及保鲜效果的影响,在固定O_2为50%的前提下,分别设置CO_2体积分数为20%、30%、40%和50%,同时以自然大气为对照,对5℃贮藏条件下西兰花的总叶绿素、叶绿素a和叶绿素b含量,叶绿素还原酶、脱镁叶绿素酶活性,乙醇、乙醛和抗坏血酸含量进行了定期测定。结果表明:过低或过高的CO_2体积分数都会对西兰花贮藏品质造成不利影响,CO_2体积分数过高易造成西兰花无氧呼吸生成乙醇、乙醛;CO_2体积分数过低则造成西兰花叶绿素还原酶、脱镁叶绿素酶活性升高,导致叶绿素迅速降解,引起西兰花黄化和抗坏血酸的损失。本实验条件下,50%O_2+40%CO_2处理可有效延缓西兰花叶绿素降解,且不会造成乙醇、乙醛的积累,达到很好的保鲜效果。

摘  要：
In order to study the effect of CO_2 concentration in O_2/CO_2 controlled atmosphere on chlorophyll degradation and quality preservation in chilled broccoli, fresh broccoli were in atmospheres consisting of 50% O_2 and CO_2 at four different concentration levels of 20%, 30%, 40% and 50% or air and then stored at 5 ℃. During storage, the contents of total chlorophyll, chlorophyll a, chlorophyll b, ethanol, acetaldehyde and ascorbic acid, and the activities of chlorophyllase and Mg-dechelatase were regularly determined. The results showed that too low or too high CO_2 proportion in controlled atmospheres had a disadvantageous effect on the storage quality of broccoli. Too high CO_2 could accumulate the contents of ethanol and acetaldehyde through anaerobic respiration. However, too low CO_2 could promote the activities of chlorophyllase and Mg-dechelatase, leading to rapid degradation of chlorophyll, yellowing and ascorbic acid loss in broccoli. Under the experimental condition in this study, 50% O_2 + 40% CO_2 treatment could effectively retard chlorophyll degradation and avoid the accumulation of ethanol and acetaldehyde and therefore have an ideal effect on quality maintenance of stored broccoli.
