​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 number of different varieties of Papaya and Papaw.
   All varieties are subject to damage resulting from chilling injury
   and therefore temperature control is absolutely critical. Papaya is
   normally picked for shipping at the three quarter ripe color stage
   and treated for insect and decay control. The treatments also vary.
   The significant difference between Asian and Pacific Papaya and
   Australian grown Papaw is in the recommended storage temperature
   range. Papaya and Papaws are very delicate fruit and require careful
   handling to minimize bruising. Packing in shredded paper is used
   extensively to minimize transport and handling damage. Damaged
   fruit is highly susceptible to post harvest rots and in particular damage
   caused by anthracnose.

   Recommended Post Harvest Temperatures
   Hawaiian Papaya – close to but not below 7ºC (44ºF).
   Australian Papaw – close to l3ºC but not below l3ºC (54ºF) (green).
   Post Harvest Humidity: 95%
   Packaging Method:
   Papaya and Papaw should have their temperature reduced to
   between 7º and 10ºC (44º & 50ºF) and 13º and 18ºC (54º & 66ºF)
   respectively within 24 hours from harvest in order to reduce decay
   and prolong shelf life. Both species are subject to ethylene induced
   ripening and where the presence of ethylene can be eliminated, then
   mature fruit has a potential storage life of around three weeks and
   ripe fruit approximately one and a half weeks. It is recommended that
   Papaya or Papaw be stored in PEAKfresh carton liners or bags. We
   recommend thatPEAKfresh be used in the shipping box prior to the
   placement of the shredded paper and the establishment of a cradle.
   Using PEAKfresh carton liners provides a degree of protection
   against ethylene damage and provides a level of humidity suitable
   for the safe storage.

   Storage Temperatures:
   Papaya around 7ºC (44ºF)  / Papaw around 13ºC (54ºF) / (green) ripe 10°C
   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
