​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. 


   There are a number of different varieties of mangoes grown and
   all are subject to severe chill damage if stored at temperatures
   below 13ºC. Chill injury is visible as a grayish scald like
   discoloration of the skin. Mangoes are normally harvested as
   mature fruit with a slight change in skin color. The best ripening
   temperatures for mangoes are between 21º and 24ºC (72º and
   78ºF). Fruit ripened at a lower temperature will not develop its full
   flavor. Mangoes can be stored at 13ºC (54ºF) for around three to
   four weeks before ripening. Commercially supplied ethylene gas
   is often used as an inducement to accelerate ripening.

   Recommended Post Harvest Temperatures
   13ºC (54ºF) and 90- 95% humidity.

   Packaging Method:
   It is recommended that a PEAKfresh carton liner be placed on
   the bottom of the carton with a plastic tray inserted into the bag
   and folded over at the top. With PEAKfresh carton liners it is
   recommended to fold the liner over instead of sealing the bag.
   Where good temperature control is not available we recommend
   that PEAKfresh be used in sheet form to line the bottom of a
   shipping box prior to the placement of shredded paper or
   PEAKfresh bubble film as a protection against bruising and a
   separate sheet of PEAKfresh be placed across the top of the fruit
   prior- to the closing of the shipping carton. Using PEAKfresh in
   this method provides a small degree of protection against ethylene
   but does also provide a level of humidity suitable for safe storage.
   Storage Temperatures:
   l3ºC (54ºF) NOT below 13ºC 90- 95% humidity.
   Important Please Read:
   All recommendations for the use of PEAKfresh products are given
   in good faith and based on proven field experience. Packaging
   method storage temperatures and humidity levels, transit and
   destination conditions are factors likely to affect the performance
   of PEAKfresh products and no liability for indirect or consequential
   damage can be accepted. We recommend that PEAKfresh
   products be trialed under local conditions before introduction to
   large scale commercial applications.
