Proper storage of fruits and vegetables is key to preserving freshness and extending shelf life. Many people have questions about the best storage methods for produce.
Frequently Asked Questions
Here are answers to some common questions about storing fruits and vegetables:
Should you wash fruits and vegetables before storing them?
It’s best not to wash most fruits and vegetables before storing. Washing removes their protective outer layer, which can lead to faster spoilage. Wait to wash produce until right before you plan to eat it.
What’s the best temperature to store fruits and vegetables?
Most fruits and vegetables should be stored at temperatures between 32°F and 50°F to maintain freshness. Colder temperatures can damage produce by freezing it.
Should fruits and vegetables be stored together?
No, fruits and vegetables have different storage requirements and should be kept separate. For example, ethylene-producing fruits like apples and bananas should be kept away from ethylene-sensitive vegetables like lettuce.
Proper Storage Methods for Fruits
Fruits are best stored unwashed in their original packaging or in a breathable plastic bag in the refrigerator. Specific fruits store best using these methods:
Apples
Store apples in the refrigerator in a perforated plastic bag. Keep apples separated from other produce since they release ethylene gas that can prematurely ripen other fruits and vegetables.
Berries
Keep berries in their original container in the refrigerator. Place the container on a shelf rather than in a refrigerator door to protect them from temperature fluctuations. Wash berries right before eating.
Citrus Fruits
Store lemons, limes, oranges, and grapefruit loose in the refrigerator crisper drawer. Citrus fruits can last 2-3 weeks when stored this way.
Grapes
Store grapes unwashed in a perforated plastic bag in the refrigerator. Grapes tend to mold quickly if washed before storing.
Melons
Whole, uncut melons can be left at room temperature. Once cut, wrap melon tightly and store in the refrigerator for 3-5 days. Melons last longer refrigerated.
Stone Fruits
Store unripe stone fruits like peaches, nectarines, plums, and apricots on the counter until ripe. Then refrigerate them unwashed in a plastic bag. Refrigeration prevents overripening.
Tropical Fruits
Pineapples, mangoes, papayas, and kiwis should be stored at room temperature until ripe. Then refrigerate them to slow further ripening. Tropical fruits last 5-7 days refrigerated.
Proper Storage Methods for Vegetables
Most vegetables keep best in high humidity. Store them unwashed in plastic bags or containers to retain moisture. Some specific storage tips:
Asparagus
Trim the ends of asparagus and stand the spears upright in a glass with an inch of water. Cover with a plastic bag and refrigerate up to a week.
Broccoli and Cauliflower
Store broccoli and cauliflower loosely wrapped in plastic bags in the crisper drawer of the refrigerator. They will last up to 10 days.
Carrots
Remove carrot tops before storing. Place carrots in a plastic bag with a damp paper towel to retain moisture. They will last 2-3 weeks refrigerated this way.
Celery
Wrap celery tightly in aluminum foil and refrigerate up to 2 weeks. The foil prevents moisture loss.
Corn
Leave corn in its husk and refrigerate promptly after purchase. Use within 2-3 days for optimal sweetness and texture.
Cucumbers
Store cucumbers at room temperature for 3-4 days. For longer storage, wrap cucumbers individually in a paper towel and refrigerate up to a week.
Leafy Greens
Rinse and dry leafy greens and place them in a plastic bag with a paper towel. Squeeze out excess air and store in the refrigerator crisper drawer up to 5 days.
Mushrooms
Place mushrooms loosely in a paper bag or box and refrigerate. Don’t use plastic, which can cause moisture buildup. Mushrooms will last 3-7 days refrigerated.
Onions
Store onions in a cool, dry, well-ventilated area. Whole dry onions can last 2-3 months this way. Once cut, tightly wrap cut onions in plastic and refrigerate.
Potatoes
Store potatoes loose in a box or paper bag in a cool, dark place like a pantry. Avoid refrigerating raw potatoes. Properly stored, potatoes can last 2-3 months.
Sweet Potatoes
Keep sweet potatoes loose in a box or basket in a dark, well-ventilated place. They will last 1-3 weeks stored around 60°F.
Tomatoes
Store ripe tomatoes stem-side down at room temperature out of direct sunlight. Keep unripe tomatoes on the counter until ripe, then refrigerate. They will last about a week refrigerated.
Winter Squash
Cure winter squash for 10 days in a warm, dry area before refrigerating. Once cured, squash will last 2-3 months in the refrigerator.
General Tips for Produce Storage
Here are some overarching tips for storing all fruits and vegetables:
- Store produce in the refrigerator crisper drawers, which have higher humidity than refrigerator shelves.
- Keep fruits and vegetables separate, since ethylene-producing fruits can overripen sensitive vegetables.
- Avoid washing produce before storing it to prevent premature spoilage.
- Inspect stored produce weekly and remove any spoiled or moldy items.
- Allow air to circulate around produce to prevent rot – don’t overpack storage containers.
Signs that Stored Produce Has Spoiled
Here are some signs that fruits and vegetables have spoiled and should be discarded:
- Mold or rotting spots
- Wrinkled, mushy, or collapsed texture
- Unusual odors
- Excess moisture or juices
- Discoloration or dark spots
If produce shows any of these signs of spoilage, it’s best to throw it out to prevent foodborne illness.
Storing Cut Produce
Once fruits and vegetables are peeled, sliced, or cut, they lose protective layers and spoil more quickly. Follow these tips for cut produce:
- Store cut fruits and vegetables in an airtight container in the refrigerator.
- Minimize air exposure by keeping the container tightly sealed.
- Use cut produce within 2-5 days for best quality.
- Consider blanching and freezing cut produce for longer storage.
Freezing Produce for Long-Term Storage
Many fruits and vegetables can be frozen for extended storage. Some tips for freezing produce:
- Select ripe, unblemished produce to freeze.
- Wash, peel, trim, and cut produce before freezing it.
- Blanch vegetables by boiling 2-3 minutes to inactivate enzymes.
- Quickly cool blanched produce in ice water to stop cooking.
- Drain produce well and pack into freezer bags or containers.
- Remove excess air and seal containers tightly.
- Label bags with contents and date.
- Store fruits and vegetables separately.
- Most produce keeps 8-12 months frozen.
Storing Produce for Juicing and Smoothies
Produce intended for juicing or smoothies can be prepped in advance:
- Wash, peel, seed, and chop fruits and vegetables.
- Spread pieces in a single layer on a sheet pan lined with parchment paper.
- Freeze the sheet pan until pieces are completely frozen.
- Transfer frozen pieces to an airtight freezer container or bag.
- This prepped produce will last 6-8 months frozen.
- Take out portions as needed for smoothies and juicing.
How to Tell if Frozen Produce Is Still Good
Check frozen fruits and vegetables for these signs of safe quality:
- No ice crystals or freezer burn on the produce.
- Produce holds original shape and texture.
- Color remains vibrant and uniform.
- Package is intact with no holes or freezer burn.
- No off odors when package is opened.
Discard any frozen produce that shows signs of spoilage.
Storing Produce for Maximum Nutrition
Proper storage preserves nutrients in fruits and vegetables. To retain vitamins and minerals:
- Store produce when fresh – nutrition declines over time.
- Avoid washing before storing to prevent premature spoilage.
- Keep storage times short and temperatures low.
- Minimize light and air exposure.
- Consume produce soon after purchase.

Conclusion
Proper storage helps fruits and vegetables stay fresh longer, reducing food waste. The ideal storage conditions – low temperature, high humidity, and limited air exposure – depend on the type of produce. Sticking to best practices maximizes shelf life so you can enjoy garden-fresh produce.
