From experience, ethylene will be put onto products. Rarely, it would be flushed into the packaging. It all depends on your type of storage. If you are packing it in the same package as that which has been flushed, yes it would mature quicker than in atmosphere. If there is a leak (e.g. incorrect micron on the ethylene packed products)and the oranges are in the same enclosure, yet again it would mature at a quicker rate. I think that the most important factors to consider is the grade of oranges before packaging (if they are almost ripe on transit, they are more susceptible to maturing); the type of packaging and the way they are stacked for transit. On the flip side, flushing the oranges with Nitrogen will delay the ripening process. Etyhlene is a ripening gas, so in effect it would make the product “more orange” quicker.

If the oranges were in a small refrig cooler along with some high ethylene producers........maybe, but if they were in a large warehouse cooler I can't see it being a factor.
