​PEAKfresh is modified atmosphere packaging (MAP) made specifically for fruit and vegetables as well

as cut flowers and plants. With a natural mineral embedded in our products, we are able to modify the
composition of the air surrounding the packaged item in order to extend the initial fresh state of the
product. PEAKfresh has long been used by growers, shippers and retail chains to preserve the
freshness of produce during transit and storage. Most recently, NASA began using PEAKfresh to

extend the life of produce sent to and consumed by the astronauts at the International Space Station. 

   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
