​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 lemons with small
   variations in their storage times. Most lemons are not ready for
   consumption immediately after harvest, but need conditioning to
   develop color, juice content and flavor. Ventilation is used to remove
   ethylene and other metabolic products produced by mold and by the
   lemons themselves. Lemons in ventilated storage should keep
   between one and six months. Under refrigerated storage conditions,
   they lose weight at a rate of 2 – 3% per month. Lemons that are of
   proper size and dark green color when picked have the longest
   storage life. Tree ripened fruit does not keep well in storage and
   should be marketed immediately. Lemons are very susceptible to
   chilling injury and must be stored at relatively high temperatures
   between 5 °- 7ºC.

   Recommended Post Harvest Temperatures
   5° – 7ºC Fast cooling is not necessary however the recommended
   temperature rang should be achieved within 24 hours of harvest.
   Post Harvest Humidity, 90%

   Packaging Method:
   Only good quality lemons should be considered for extended
   storage. We recommend that lemons packed in fiber board cartons
   have a slightly oversize sheet of PEAKfresh film (bigger than the top
   of the box) and tucked down the inside of the box, but not impeding
   air flow. This application of PEAKfresh is to provide a surface to
   encourage maintenance of humidity, and also to provide a capacity
   to treat small volumes of ethylene gas produced by the lemons. For
   maximum storage conditions of beyond four months, we recommend
   that a further sheet of PEAKfresh film be used as a divider between
   the top and bottom layers of stored lemons. We do not recommend
   the placement of a further sheet in the bottom of the box as this may
   be a trap for excessive condensation and induce the development of

   Storage Temperatures:
   Must be maintained between 5ºC and 7ºC at a 85-90% humidity
