Embodiment 1
[0028] A fresh-keeping method for broccoli suitable for logistics transportation, specifically implementing the following steps: packing broccoli, ethylene remover and silica gel desiccant into an airtight container, maintaining the air relative humidity in the airtight container at 85%-95%, using an air-filled The equipment is replaced and filled with fresh-keeping mixed gas in the airtight container. The volume of the gas filled is about 3.5 times the volume of broccoli, and the logistics transportation temperature is 20-25 ° C, of which O 2 The volume fraction of the mixed gas is 55%, and the rest is CO 2 , and then airtight and fresh, and at the same time carry out logistics transportation.
Embodiment 2
[0030] A fresh-keeping method for broccoli suitable for logistics transportation, specifically implementing the following steps: packing broccoli, ethylene remover and montmorillonite desiccant into an airtight container, maintaining the air relative humidity in the airtight container at 85%-95%, Use an inflatable device to replace and fill the airtight container with a fresh-keeping mixed gas. The volume of the gas is about 2.5 times the volume of the broccoli, and the logistics transportation temperature is 10-12 ° C, where O 2 The volume fraction of the mixed gas is 70%, and the rest is CO 2 , and then airtight and fresh, and at the same time carry out logistics transportation.
Embodiment 3
[0032] A fresh-keeping method for broccoli suitable for logistics transportation, specifically implementing the following steps: packing broccoli, ethylene remover and fiber desiccant into an airtight container, maintaining the relative humidity of the air in the airtight container at 85%-95%, using an air-filled The equipment is replaced and filled with a fresh-keeping mixed gas in a closed container. The volume of the gas filled is about 4.5 times the volume of the broccoli, and the logistics transportation temperature is 0-2 ° C, of which O 2 The volume fraction of the mixed gas is 95%, and the rest is CO 2 , and then airtight and fresh, and at the same time carry out logistics transportation.
