How To Know If Blueberries Are Spoiled

How To Know If Blueberries Are Spoiled

Unwashed blueberries have a protective blossom on the surface that keeps them from spoiling over time. If you store your blueberries in your refrigerator or freezer, you will have enough time to enjoy them before they spoil.

They also need to stay out of the way of other foods, because they produce gases which make them ripen more quickly. If any blueberries are spoilt or have gone bad, then throw them out before you put them in storage so you do not get contamination. To prevent humidity and other contaminants, you should store your blueberries in a sealed, air-tight container straight from the store.

When dried blueberries are fully dried, let them cool down before you store them in a sealable container. Once washed, put blueberries in a clean plastic bag, then store blueberries in a refrigerator until you are ready to consume. When storing your blueberries, you can put and leave them out at room temperature, in the freezer bag, or inside of your refrigerator.
