I loved Dynamic Greens. I used to just suck on the cubes and would feel it working. I figured less exposing it to air by waiting for it to melt in the water. It tasted that good..wasn't bitter like fresh junk I've tried. It's like the same high you get when you drink fresh juices so to me it's proof that it's just as good as fresh.
I also hated the packaging. I haven't used them in years; I thought they had changed it by now.
One thing you could do is just quickly pop them all out of the buy the Ziplocks with the pump to suck the air out of the bags.
It's only a couple bucks and really does work. It takes seconds. http://www.ziploc.com/Products/Pages/VacuumFreezerSystem.aspx
