When I first saw Evert-Fresh Bags, I thought they were a gimmick. The thought of a bag being able to keep produce fresh for up to a month seemed impossible. But one of my old colleagues said that they worked for her, which made me curious enough to try them myself.
The bag is supposed to keep produce fresh by slowing down the ripening process and keeping bacteria from forming. The claims are pretty impressive — it absorbs the harmful gases that fruits and veggies give off like ethylene and ammonia, controls humidity, and minimizes moisture. From a scientific standpoint I have no idea if that's what's really happening inside those bags, but I can say that they do work.
To hear how they worked for me,
I think I store my fruits and veggies pretty well to begin with, so I was pretty shocked that the bags impressed me. I use mine to store lettuce and berries, and they definitely work in keeping my produce fresh longer than my previous storage methods. I don't let produce sit around too long to begin with, but after returning from a week-long vacation nothing I left in the fridge spoiled — not my strawberries, arugula, or peppers, all of which had been there two weeks!
I still try and eat my produce ASAP, but the bags are a great option if you're worried about letting produce you buy from a farmers market go to waste or for times you can't get through your produce fast enough.
