If your produce rots after just a few days, you might be storing incompatible fruits and veggies together. Those that give off high levels of ethylene gas—a ripening agent—will speed the decay of ethylene-sensitive foods. Keep the two separate.
Use trapped ethylene to your advantage: To speed-ripen a peach, put it in a closed paper bag with a ripe banana. One bad apple really can spoil the whole bunch. Mold proliferates rapidly and contaminates everything nearby, so toss any spoiled produce immediately.
For longer life, keep your produce whole—don't even rip the stem out of an apple until you eat it. "As soon as you start pulling fruits and vegetables apart," says Barry Swanson, a food scientist at Washington State University, "you've broken cells, and microorganisms start to grow."
Cold-sensitive fruits and veggies lose flavor and moisture at low temperatures. Store them on the counter, not in the fridge. Once they're fully ripe, you can refrigerate them to help them last, but for best flavor, return them to room temp.

The ABCs of Fresh
The main way to lengthen shelf life is by using cold temperatures to slow food's respiration, or 'breathing' process," explains Marita Cantwell, PhD, a postharvest specialist at the University of California, Davis. In general, the warmer the temperature, the faster the rate of respiration, which is why refrigeration is critical for most produce. But while you want to slow it down, you don't want to stop the breathing altogether. "The worst thing to do is seal fruits and vegetables in an airtight bag," says Barry Swanson, a food scientist at Washington State University. "You'll suffocate them and speed up decay."
Some fruits emit ethylene, an odorless, colorless gas that speeds ripening and can lead to the premature decay of nearby ethylene-sensitive vegetables. Put spinach or kale in the same bin as peaches or apples, and the greens will turn yellow and limp in just a couple of days. So the first trick is to separate produce that emits ethylene from produce that's sensitive to it. (See "Gas Wars" sidebar.)

Fastest to Slowest Spoilers: What to Eat First You can enjoy fresh fruits and vegetables with just a single weekly trip to the supermarket, with proper storage and a little planning. The key is eating the more perishable produce early on. Use this guide, right—created with the help of Marita Cantwell, PhD, postharvest specialist at the University of California, Davis—based on a Sunday shopping trip. The timing suggestions are for ready-to-eat produce, so allow extra days for ripening if you're buying, say, green bananas or not-quite-ripe pears. And remember, looks count. Appearance—vivid green spinach; smooth, unbruised peaches; plump oranges—is the best clue to whether fruits and veggies are fresh to begin with. | |||
