Arlene,
I know nothing, but here's an idea that I found:
http://homecooking.about.com/o...
First, they say that going limp doesn't harm the flavor, but that evades the question. And you can't sell it frozen, though the author thinks that keeps flavor better than drying.
But they suggest, besides storing it cut in a glass with water, storing that cold, and
also loosely wrapping some damp paper towels around the tops, then pulling a plastic bag over the towels.
