fresh food

I don't know if you have King Soopers in your neck of the woods, but they have "Green Bags" for their produce. It is a regular plastic bag but releases the gasses that cause rotting. I REALLY helps in keeping produce fresher a lot longer. There is also an as seen on TV product called Grren bags.

This might be overkill, but here it goes... Some plants produce a gas called ethylene when they ripen. Other plants are sensitive to ethylene gas, which makes them ripen faster. For example, bananas create and are also sensitive to ethylene gas. That means as they ripen, they give off ethylene, but then also take it in and ripen faster. Which is why a bunch of bananas might be just beginning to ripen one day, then the next time you look at them are all brown.

Here is a chart that shows how other produce is effected by the gas:

This article also gives some guidelines:

Finally, you want to make sure that most produce is stored correctly. If you wash the produce before you put it in your refrigerator then put it in a plastic bag inside the refrigerator, the moisture from the recent washing will make it decay faster. I printed out the following chart and have it hanging on my refrigerator.

It's tough to keep these little buggers from going bad before you get to eat them. I still have trouble sometimes, but knowing the stuff above has helped.
