Response of pawpaw fruit to cold storage temperature and duration.     Pawpaw (Asimina triloba (L.) Dunal) is a highly perishable climacteric fruit, softening rapidly o­nce ripening commences which may limit its marketability.Preliminary cold storage studies indicated in may be stored for 1 month at 4 °C and ripen normally upon removal to ambient temperature.

The objective of these studies is to determine the optimum cold storage temperature and maximum storage life of the fruit.Fruit were stored at –2, 2 and 6 °C for 1, 2, 4, 8 and 12 weeks, and were then ripened upon removal to ambient temperature.Through 4 weeks, fruit exhibited adequate firmness upon removal from cold storage, a at 8 and 12 weeks fruit held at2 and 6 °C were very soft.Irrespective of storage temperature, at 8 weeks fruit showed a delay in a climacteric-like respiratory increase, and by 12 weeks a respiratory climacteric was not apparent.An ethylene climacteric was evident by fruit from all temperature and storage periods except those held at 6°C for 12 weeks.

The results suggest that common cold storage at –2 to 2°C will maintain pawpaw fruit quality and ripening potential for 4 weeks, but that such storage for longer periods is questionable.
