Choose frozen blueberries that have been “snap frozen” and are well-packaged with a soft plastic lining and resealable packaging. Look for individually frozen berries and avoid those that have thawed and refrozen. Alternatively, freeze fresh berries yourself by spreading them on a baking sheet and storing them in an airtight container for up to a year.
There are a few different things you should look for to help you choose the best frozen blueberries possible, including how they’re frozen and packaged. In general, you should look for berries that have been “snap frozen,” as this tends to help them retain as many vitamins and nutrients as possible. You should also look for packages that can be easily resealed and try to avoid any that look bundled up. While there are many brands of commercially frozen blueberries that you can purchase, you can also purchase fresh berries and freeze them yourself.
Frozen blueberries are typically grown by commercial farmers who oversee the process by which they are harvested and frozen. One of the most important things to look for on packages of these berries is how well they are frozen before shipping. Look for the term “flash frozen,” which indicates that they have been frozen through a process that reduces their temperature very rapidly. This helps ensure that purchased frozen blueberries have as much nutritional and vitamin value as possible, although some antioxidants and other beneficial compounds are lost during freezing regardless of the process used.
When choosing frozen blueberries, you should also consider the packaging used by different brands. You should try to find berries that come in packaging with a soft plastic inner lining, and you should look for resealable packages to make storing them easier for you. As you sort through several packages of frozen blueberries, look for the individual berries inside them rather than clusters of berries. If you feel the berries clumping together, this could be a sign that they have thawed and refrozen, which can decrease their texture and potentially reduce their nutritional value.
You might also consider making your own frozen blueberries using fresh berries you can buy from local growers. Fresh berries can be spread out on a baking sheet, and you typically don’t have to worry about washing them before freezing. The baking sheet can be placed in a freezer and the berries should be left to freeze for several hours. Once frozen, you can place them in an airtight container and keep them in the freezer for up to a year. If you want to use some of the frozen blueberries, you can simply remove them from the container and rinse them lightly before using.
