Most people intuitively believe that fresh blueberries are more nutritious. But the reality is somewhat different. Blueberries intended for freezing are usually picked at their peak ripeness, when they contain the most vitamins and anthocyanins – blue-black pigments that have exceptional antioxidant power.

Immediately after harvesting, they are usually quickly blanched and deep-frozen, which preserves most of these nutrients.

Ice crystals that unlock the power of blueberries

During freezing, tiny ice crystals form inside the blueberry, breaking down its cell walls. The result? When they're thawed, the nutrients, especially anthocyanins, are released even more easily.
