Q. Is the amount of Vitamin C in frozen orange juice figured before or after mixing? It seems to me that a lot is lost when it is exposed to oxygen during the mixing process.
A. The nutrition facts label information for frozen orange juices is based on a serving size of 8 fluid ounces of juice which suggests the concentrate has been mixed. Vitamin C is a sensitive nutrient and degrades in the presence of heat, light, and oxygen. Vitamin C levels in frozen orange juice tend to be higher than packaged orange juice due to pasteurization and packaging processes. Nonetheless, a serving of 100% orange juice from either form provides 100% of your daily vitamin C needs.
