How can I extend the shelf life of kiwanos I am shipping?

Question

Dr. Cantwell: I found on the Internet an article written by you in which you recommend storing kiwanos at 13-15C. I am an exporter of exotic fruits and am exporting kiwanos to Europe.  My client says that the shelf life for my kiwanos is short, 2-3 weeks. They are storing the fruit at 10-12 C. I would sincerely appreciate your comments about this problem. Thanks in advance and best regards.

Answer

In our 1996 research summary we found that 10-12°C was too low if the fruit was stored for 2 months.  These fruit had severe decay, most probably a result of chilling injury at those temperatures.  The fruit was stored at 15°C successfully for 5 months.  Our study was very limited but it was consistent with other reports in which warmer temperatures were used for kiwano.  I have had the opportunity to observe the fruit at some specialty produce wholesalers and the main problems appear to be maturity (too immature at harvest; fruit should be yellow-orange for good composition and flavor) and damage to the spines which leads to early decay.   They typically handle them at moderate temperatures (15-20°C).  I hope this is helpful.
