Vegetables That Should Not Be Stored in the Refrigerator
Potatoes, taro, sweet potatoes, and yuca (cassava, manioc) should not be refrigerated.
1. Many fruits and vegetables should only be stored at room temperatures. Refrigeration can cause cold damage or prevent them from ripening to good flavor and texture. For example, pink tomatoes ripen to a better taste and red color if they are left at room temperature.
Avocado, apples, bananas, citrus fruits, berries, peaches, apricots, and nectarines should be stored out of the fridge. Refrigerating these fruits will result in loss of flavors and textures.
You'll have to store your carrots in the refrigerator, but how you store them can actually make a difference. Raw carrots, when properly stored will usually stay fresh for around 3 to 4 weeks in the fridge. If your carrots are sliced or chopped, you can store them in the fridge and they'll last for about 2 to 3 weeks.
Refrigerate any unconsumed fully ripe tomatoes, but allow them to come to room temperature before serving them. (To speed up this process, slice them while still cold—slices will warm up much more quickly than an intact fruit.) One study we've read suggests that refrigerating for no longer than three days is optimal.
Go ahead and refrigerate ripe tomatoes.
Put both cut and whole ripe tomatoes in an airtight container in the refrigerator to prolong their shelf life.
Tomatoes contain an enzyme that reacts to cold temperatures and causes its cell membrane to break down, leaving you with a piece of fruit that's mushy and mealy. "You're essentially zapping flavor and texture from a tomato when you refrigerate it," says Gregory Lofts, deputy food editor at Martha Stewart Living.
Don't refrigerate. Store in a cool, dark place with relatively high humidity. Allow air circulation. Keep separate from onions, bananas, and other ethylene-producing items.
Do Fresh Eggs Need to Be Refrigerated? Freshly laid eggs need to be refrigerated immediately. Fresh eggs purchased from a farmers market need to be refrigerated as soon as you get home. Per USDA guidelines, eggs should be stored at 40 degrees F or below to help minimize the risk of Salmonella.
Once cut or peeled, fresh produce should be refrigerated within 2 hours. If it is left at room temperature for more than 2 hours, throw it away. Remember: To prevent foodborne illness, buy good-quality fruits and vegetables, store them properly and wash them thoroughly.
Stash the broccoli in a cold part of your refrigerator — like the crisper drawer — preferably away from fruits and that produce excessive ethylene gas like apples. If there's no room in the crisper, store it on a shelf near the back of the fridge.
Once an onion has been peeled, it is best stored in the fridge to avoid contamination. Halved, sliced, or chopped raw onions should also be refrigerated, in an airtight container or resealable plastic bag.
Even though cucumbers are prone to chilling injury, the fridge is still the best place to store them. At room temperature, cucumbers will only last for about two days. So, what's the solution? Store cucumbers in the warmest part of the fridge — towards the front, furthest from the cooling elements.
Don't store potatoes in the fridge.
Raw potatoes have lots of starches, and the cold temperatures can turn the starches into sugars. This can make your potatoes turn sweeter and darker during cooking.
Apples are safe at room temperature, but their higher ethylene content contributes to faster ripening. Apples stored in the refrigerator can last for several weeks. Cut produce is more susceptible to pathogens, so storing in the refrigerator can limit pathogen growth.
The ideal place to store bananas is on the countertop, where they can ripen naturally. You can refrigerate bananas once they've achieved your ideal level of ripeness; however, refrigerating bananas too soon or for too long can have detrimental effects on your bunch.
The refrigerator will slow avocados in the ripening process, so unless you're stacked with too many avocados for your weekly use, keep them out at room temperature. The cold temperature also hardens the texture of a ripe avocado, which might not be ideal for some when it comes to mealtime.
Ripen fruit at room temperature. Once they are ripe, refrigerate. Apples, cherries, grapefruit, grapes, oranges, pineapples, strawberries, tangerines and watermelon are received ripe and should be refrigerated.
*Never keep your bread in the fridge. The starch molecules in bread recrystallize very quickly at cool temperatures, and cause the bread to stale much faster when refrigerated. *Shop-bought loaves should be kept in an air-tight plastic bag at room temperature rather than in the fridge.
You should store summer squash (like zucchini) in the fridge, but thick-skinned squash like acorn, butternut, or kabocha should stay at room temperature.
It is all due to storage lifetime. Lettuce is particularly perishable, compared to many other vegetables. You will get a considerably longer storage lifetime if it is refrigerated, rather than kept at room temperature.
Wilting occurs when carrots aren't kept properly hydrated, so the first step to keeping carrots fresh for as long as possible is to remove the green, leafy carrot tops. (Note that if you're buying carrots in a bag at a grocery store, chances are good that the producer has already done this for you.)
