We grow soursop in Grenada. We have been transporting it from Grenada to Los Angeles,CA via air. The transit in total is about 3 days. The problem were having is that days later the fruit becomes black and hard as a rock. Any suggestion as why this occurs?

Plane Storage can bring about some rather extreme conditions. It may be that the fruit is freezing while on the plane, which would cause it to shrivel. This would have to be my guess. If you can send pictures, maybe I can see something that might tell me what's going on.
