摘要

为探究泡沫箱包装抑制黄瓜在冷藏期间冷害的机理,分别设置无包装4 ℃贮藏组(对照组)、无包装模拟泡沫箱温湿度贮藏组(模拟组)、泡沫箱包装后4 ℃贮藏组(泡沫箱组)研究泡沫箱逐步降温和气体微环境对冷害的影响。结果表明,相较于对照组,模拟组及泡沫箱组通过逐步降温均能抑制黄瓜冷害指数和超氧阴离子自由基产生速率,降低呼吸速率、相对电导率及丙二醛含量的上升,保持较高的硬度,同时提升了总酚及花青素含量并增强抗氧化酶如过氧化氢酶、过氧化物酶、超氧化物歧化酶的活性,提高黄瓜抗冷性,抑制冷害的产生。泡沫箱组的效果优于模拟组,说明泡沫箱在实现逐步降温的同时,还通过控制泡沫箱中的气体微环境起作用,结合冷害抑制效果来看,泡沫箱的逐步降温功能比其控制气体微环境功能发挥的作用更大。

Abstract

To explore the mechanism of foam box packaging inhibiting the chilling injury of cucumber during refrigeration, the unpacked 4 ℃ storage group (control group), the unpacked simulation foam box temperature and humidity storage group (simulation group), and the 4 ℃ storage group after foam box packaging (foam box group) were used to study the effects of foam box gradually cooling and gas microenvironment on the chilling injury. Results showed that compared with the control group, both the simulation group and the foam box group could inhibit chilling injury index and superoxide anion (·O-2) production rate. They also reduced the respiration rate, relative electrical conductivity and malondialdehyde (MDA) and maintained the high hardness of cucumber by gradually cooling. At the same time, the contents of total phenols and anthocyanins were increased, and the activities of antioxidant enzymes such as catalase (CAT), peroxidase (POD) and superoxide dismutase (SOD) were enhanced to improve the cold resistance of cucumber and inhibit the generation of chilling injury. The effect of the foam box group is better than that of the simulation group. In addition, gradual cooling plays a greater role than controlling the gas microenvironment from the perspective of the cooling damage inhibition effect.
