I wanted to know if anyone has field tested these. I heard they work great. There are a variety of brands making them now, here is an example:

I think the way it works is the plastic is semipermeable to ethylene, letting it out but not back in, making it reusable.

Good ol' ethylene. Old produce codgers like me remember pallets full of hard green bananas ripening in a few days inside rooms filled with ethylene gas. We also know to keep fresh fruit out of plastic bags.

When I was a kid we weighed every produce item on a hand scale and the put the stuff into paper bags with the price written in green crayon. The scale was too high for most folks to see the small potato hidden in the front of the weighing tray. That potato would get weighed hundreds of times a day but never placed in a bag. If it was discovered, the clerk would act surprised and remove it....only to replace it when the customer was gone. :o

So much for the good old days. :roll:

Paper bags ripen fruit much more naturally than plastic because of paper's permeability to ethylene. Some ethylene remains in the bag, but not enough to promote rot. Try taking your unripe fruit out of the plastic and putting it into paper when you get home and leaving it on the counter (it won't ripen in the fridge) until ripe. You will be pleasantly surprised with the result. :wink:

BTW, the link says that there is a fine clay coating on the Green Bags and that they work by absorbing the ethylene. If that is true then the fruit could come out of the paper bag once ripe and get stored in the Green Bags until use. Both types of bags can get reused dozens of times this way.

while it is a good idea - I always come back to the thought that fresh food is weighty (backpacker mentality)... so I take dehydrated and freezedried fruit and veggies... I also grow my own sprouts on our trips if I want fresh green stuff.
