| Abstract: |
| The work aims to design an air-conditioned packaging bag suitable for transportation and sale of fresh jujube. The changing characteristics of post-harvest physiology of niumama jujube were studied by experiment. Then, combined with theoretical mathematical model of air-conditioned packaging, and by selecting appropriate packaging materials, the number of packaging bags required by a certain amount of fruit was calculated. Finally, in combination with green consumption and humanized design, the profile diagram of air-conditioned packaging bag was drawn. The 0.25 m2 low density polyethylene (LDPE) fresh-keeping film (thickness of 0.03 mm and permeability coefficient ratio β of 2.75) was selected as the material to manufacture air-conditioned bags. The structure of air-conditioned bag conformed to a variety of functions, such as usage for multiple times, core recovery, vertical display and convenient transportation. The proposed design has improved the edible value and prolonged the storage period of niumama jujube. |
