Green beans when harvested are still in the growing stage of development and are highly perishable. Chilling injury to beans will occur when storage temperatures are 5ºC or below. The most common quality test for beans is the ‘snap’ test. Beans are also subjected to damage by surface pitting and reseating which is aggravated by the presence of free moisture, especially on produce in the centre of cartons. It is generally recommended that the best method for pre-cooling beans following harvest is using hydro-cooling. It is important that the water used for hydro-cooling contain a fungicide so as to prevent the spread of disease.
Recommended Post Harvest Temperatures
Around 7ºC (43ºF) and 95% humidity.
Packaging Method
Beans are normally packed in five and 10 kilo boxes and it is important that they be palletized for refrigerated storage to allow maximum air flow through the box ventilation holes. Beans should be packed in a PEAKfresh carton liner with the top of the liner folded and not sealed. It is essential that beans be properly pre-cooled before packaging into PEAKfresh so as to reduce their respiration rate. In areas where beans are likely to be subject to changes in temperature during transportation and handling, we recommend the placement of additional ventilation holes in the PEAKfresh carton liner.
Storage Temperatures
7ºC (42ºF) and 95% humidity.
