研究4℃、10%O2结合不同体积分数CO2(10%~50%CO2)处理对鲜切结球莴苣的主要品质和生理指标变化的影响。结果表明:高体积分数CO2导致了细胞膜通透性增加;10%O2+30%CO2气体组合显著抑制了多酚氧化酶、过氧化物酶和过氧化氢酶的活性,延缓了组织的衰老和褐变,并较好地保持了鲜切结球莴苣中叶绿素、VC和还原糖含量。感官评价结果表明,在10%O2+30%CO2气体组合条件下,鲜切结球莴苣贮藏15d仍具有商品价值。
Effect of Modified Atmosphere Packaging with Different Concentrations of Carbon Dioxide on Storage Quality and Physiology of Fresh-Cut Iceberg Lettuce
The effect of modified atmosphere packaging(MAP) with systems consisting of 10% O2 and different concentrations of CO2(10%-50%) on major quality and physiological indices of fresh-cut iceberg lettuce stored at 4 ℃ was investigated.The results showed that high CO2 concentrations could increase the membrane permeability of iceberg lettuce.Significantly,10% O2 +30% CO2 inhibited the activities of PPO,POD and CAT,delayed tissue aging and browning,and maintained the contents of chlorophyll,vitamin C and sugar content well.The sensory evaluation results showed that the fresh-cut iceberg lettuce exposed to 10% O2 +30% CO2 still had commercial value after 15 days of storage.
