目的 为提高果蔬气调包装的设计效率， 对果蔬气调包装CAD方法进行研究。方法 在建立果蔬气调包装数学模型、 果蔬产品呼吸速度及塑料薄膜透气性数据库的基础上， 利用Matlab GUI开发果蔬气调包装CAD系统， 并进行实例研究。结果 系统界面清晰， 操作简便。可根据产品的理想气调环境参数， 选择合适的薄膜材料， 计算有利于气体交换的塑料薄膜面积或厚度。果蔬产品呼吸速度数据库包含17种果蔬呼吸速度模型， 塑料薄膜透气性能数据库包含21种塑料薄膜材料的透气性数据。结论 该系统可快速进行常见果蔬产品的气调包装设计。

In order to improve the design efficiency of modified atmosphere packaging (MAP) for fruits and vegetables, a CAD method for MAP design of fruits and vegetables was studied. The CAD system was developed via MATLAB GUI based on the establishment of mathematical model of fruits and vegetables packaging, databases of respiration rate of fruits and vegetable, and database of permeability of plastic films. The system was applied in a case study. The system had clear interfaces that were easy to operate. According to the ideal gas environment parameters of products, the software could select suitable packaging materials and calculate the area or thickness of the plastic film beneficial for gas exchange. Two databases were built in the software, including the respiration rate database containing the respiration rate models for 17 fruits and vegetables, and the film permeability database containing the permeability data for 21 polymeric films. This system could facilitate quick MAP design of common fruit and vegetable products.
