Undesirable taste

If the berries are past their expiry or best-by and there are no visual signs of spoilage but you are unsure whether you should discard or consume them, your best bet is to taste them. This works well for dried berries as well. If the taste is off, feel free to discard them without guilt.

Blueberries with freezer burn or discolored patches are not unsafe for consumption but they won’t taste the same. It is your call to whether to toss them or consume them before they are really bad.

How to store blueberries?

Do not wash them before storing them 

Blueberries are quite perishable and moisture is the enemy of their keeping quality. It is because moisture supports the growth of fungus which rapidly spreads and spoils berries. Therefore, always with the blueberries right before consuming them. 

Moreover, washing and rinsing also stip the berries off of their protective bloom, which prevents the berries from moisture loss and decay.

Check the batch properly before storage 

Remove the bitter stems of the blueberries before storage. Moreover, remove the rotten berries so that they don’t contaminate and spoil the whole lot during storage.

Refrigerate the blueberries 

If the blueberries aren’t to be consumed within a few days of purchase, store them in the fridge. For storage, put them in food storage or any other air-tight container lined with 2-3 good quality paper towels. 

Freeez the blueberries If they are overripe 

If the blueberries are overripe or you bought a large quantity freshly off the farmer’s market, freeze them for extended storage.

Dry the blueberries 

Dried blueberries last longer, are absolutely delicious, and make for excellent snack food. Blueberries can be easily dried using a dehydrator or in an oven. First, they are boiled to peel off their skin. 

Next, spread the berries on a baking tray and keep them in the oven at 140 ºC for about 4 hours. Stir the blueberries after every 30 minutes. Once the berries are dried and cooled down, transfer them to an air-tight container.

Wash with vinegar 

Rinsing the blueberries in a solution of 1 part vinegar and 3 part water will remove the spoilage microbes from the surface and prevent the mold from growing.

It will make the berries last longer. To remove the vinegar, give the blueberries a final rinse with clean potable water.

Can you freeze blueberries?

Freezing is a great way to make the blueberries last longer. If stored correctly in the freezer, blueberries will easily last 6 months and up to a year. 

Start off by thoroughly washing the blueberries with clean potable water. Pat dry the berries with paper towels. Then spread them in a single layer onto a baking tray or sheet. 

Slide the tray into the freezer and let the berries pre-freeze for about 2-3 hours or until the blueberries are frozen solid. 

Transfer the frozen blueberries to a high-quality resealable or zip-lock bag. Remove as much air as possible from the bag. All the bag and chuck it into the freezer.
