Because vitamins in fruit juices are water-soluble vitamins that can be lost with the air, and carton-packed juices inevitably have air leakage, the longer the storage, the more vitamin C is lost. Take a box of refrigerated fresh orange juice for example. Unopened boxed orange juice contains between 27 and 65 mg of vitamin C and can be reduced to 0 to 25 mg after four weeks.
According to a report from the Associated Press, a study by the American Nutritionists Association showed that the content of vitamin C in carton-packed juice drops by 2% per day, so the longer it is stored, the more vitamin C is lost.
The association's nutritionists found that it is also 100% fresh juice, but different packaging will affect the preservation of its vitamins.
