How do frozen blueberries compare nutritionally to fresh ones
Studies have shown that freezing blueberries soon after picking can preserve or even increase their antioxidant content, particularly anthocyanins which are responsible for their blue color.
Freezing disrupts the berry's cell structure, making the antioxidants more bioavailable to the body.
When frozen at peak ripeness, blueberries retain similar or greater concentrations of vitamins, minerals, and fiber compared to fresh berries.
Nutrients like vitamin C, vitamin B6, folate, and manganese are well preserved in frozen blueberries.
Frozen blueberries are available year-round and are often less expensive than fresh berries. They have a longer shelf life, reducing food waste compared to fresh berries that spoil more quickly
Freezing can affect the texture of blueberries, making them softer and less firm compared to fresh berries.
Commercially frozen blueberries may contain added sugars, so it's best to choose unsweetened varieties.
