摘要
为探究臭氧处理对冬枣贮藏品质变化的影响,以白熟期的山东沾化冬枣为材料,探讨(0.00±0.50)℃贮藏条件下,不同臭氧浓度(0、2.14、10.72、21.44 mg/m3)对冬枣贮藏品质的影响。结果显示:臭氧处理能减缓冬枣果实硬度的下降,维持较高的可溶性固形物含量,降低超氧阴离子产生速率和过氧化氢含量以及丙二醛的含量,促进抗坏血酸过氧化物酶(ascorbate peroxidase,APX)和过氧化物酶(peroxidase,POD)的活性,通过对比不同处理组的冬枣品质变化趋势,发现T1处理组保鲜效果较好,以上结果表明适宜浓度臭氧处理可延缓贮藏期冬枣的成熟衰老,维持果实具有较高的品质和营养价值。
To investigate the effect of ozone treatment on the storage quality of ripe-stage winter jujubes in Shandong Zhanhua,the study examined the effect of different ozone concentrations(0,2.14,10.72,and 21.44 mg/m3)on the storage quality of the jujubes at(0.00±0.50)℃.The results demonstrated that ozone treatment effectively decelerated the decrease rate in fruit hardness,preserved higher soluble solids content,suppressed the generation speed of superoxide anions and contents of hydrogen peroxide and malondialdehyde,and enhanced the activities of ascorbate peroxidase and peroxidase.A comparison of the quality changes among various treatment groups showed that the T1 treatment group enjoyed the most favorable preservation effect.These findings suggested that ozone treatment in an optimal concentration can effectively retard the aging process of winter jujubes during storage,thereby preserving their superior quality and nutritional value.
