中文摘要:

      气调包装(modified atmosphere packaging, MAP)可以有效延长果蔬保鲜期, 减少果蔬储运过程中腐败变质造成的巨大经济损失。其中自发气调包装利用果蔬自身的呼吸作用和包装薄膜选择透过性, 建立适宜果蔬保存的气体环境, 降低果蔬的生理消耗, 对延长保鲜期有明显功效。自发气调包装关键技术是果蔬呼吸速率和包装内外气体交换。本文综述了呼吸速率3种测量方法, 分析了基于酶动力学和化学反应原理构建的果蔬呼吸速率模型, 并基于阿伦尼乌斯方程和一元一次线性方程讨论了模型参数对温度的依赖性, 按照逻辑关系整合模型, 总结出求解果蔬呼吸速率的路径以及选择适宜包装材料的方法, 为果蔬保鲜包装的研究提供支持。随着技术的发展, 未来呼吸速率模型将更加细化、精准化, 自发气调包装技术将成为果蔬储运保鲜重要的应用方向。

英文摘要:

      Modified atmosphere packaging (MAP) can effectively prolong the fresh-keeping period of fruits and vegetables, and reduce the huge economic losses caused by spoilage during during storage and transportation. Among them, spontaneous MAP uses the respiration of fruits and vegetables and the selective permeability of packaging film to establish a gas environment suitable for the preservation of fruits and vegetables, reduce the physiological consumption of fruits and vegetables, and has obvious effect on prolonging the preservation period. The key technologies of spontaneous MAP is respiration rate of fruits and vegetables and gas exchange inside and outside the packaging. This paper summarized 3 kinds of methods for measuring the respiration rate, analyzed the respiration rate model based on enzyme kinetics and chemical reaction principle construction, mean while described the dependence of model parameters on the temperature based on Arrhenius equation and one-variable linear equation, and integrated the model according to the logical relationship, we concluded the path to solve the respiration rate of fruits and vegetables and the method of selecting suitable packaging materials, and provided support for the research on fresh-keeping packaging of fruits and vegetables. With the development of technology, the respiration rate model will be more refined and precise, and spontaneous MAP technology will become an important application direction of storage, transportation and preservation of fruits and vegetables.
