Compatibility & Temperature
Group 1. Ice never in contact with commodity. Ethylene producer.
USDA recommended storage 30° to 40° F. (-1.1° to 4.4° C.)
Approximate freezing point 30.0° F. (-1.1° C.)
Transport Apples at the same temperature as maintained in the storage facility. Elevation of temperature will accelerate the
dormant ripening process, and lower temperatures may result in chilling injury. Storage apples are more easily bruised than non-storage apples. To achieve year-around availability a good percentage are placed in controlled atmosphere storage facilities which require constant monitoring of both temperature and gases with oxygen regulated at between 2% and 3% and CO2 at 1% to 2%. Since apples produce ethylene, which enhances ripening, it is also necessary to remove the ethylene from the storage facilities.
Controlled storage techniques not only greatly arrest the ripening process, but also control both pathogens and insects. It is extremely important to remember that the atmosphere in these facilities will not support human life.

Apples produce ethylene and should
not be shipped with ethylene-sensitive products. Apples also readily absorb odors, and care must be used in selecting compatible product for mixed loads.
