In tough tests, we put bananas, peaches, apples, melons, blackberries, strawberries, basil, asparagus, tomatoes, broccoli, grapes, lettuce, and carrots in Green Bags for up to five weeks. We stored the same foods for the same time in regular plastic food-storage bags on a counter, in a refrigerator, or in plastic supermarket bags.
When we saw green in Green Bags, it was sometimes mold. Only bananas fared much better in them. And at almost 85 cents each, Green Bags are much pricier than the typical food-storage bags.
