Superior Nutritional Preservation
The flash-freezing technology employed in processing blueberries represents a significant advancement in nutrient preservation. When blueberries are frozen at their peak ripeness, they undergo a rapid freezing process that forms minimal ice crystals, effectively locking in essential nutrients, vitamins, and antioxidants. This preservation method ensures that the berries maintain up to 90% of their nutritional value, particularly their high levels of vitamin C, vitamin K, and manganese. Scientific studies have shown that frozen blueberries often contain higher levels of anthocyanins compared to fresh berries that have been stored for several days. These anthocyanins are crucial antioxidants that contribute to the berries' health benefits, including improved cardiovascular health and cognitive function. The preservation process also maintains the berries' fiber content and natural sugars, making them nutritionally equivalent or superior to fresh berries, especially when considering long-term storage and transportation factors.
