Storing Fruits and Vegetables Part 2

REFRIGERATE THESE GAS RELEASERS:

Apples
Apricots
Canteloupe
Figs
Honeydew

For produce that is best stored in the refrigerator, remember the following guidelines.

Keep produce in perforated plastic bags in the produce drawer of the refrigerator. (To perforate bags, punch holes in the bag with a sharp object, spacing them about as far apart as the holes you see in supermarket apple bags.)

Keep fruits and vegetables separate, in different drawers, because ethylene can build up in the fridge, causing spoilage.

When storing herbs (and interestingly, asparagus, too), snip off the ends, store upright in a glass of water (like flowers in a vase) and cover with a plastic bag.

“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.
