Question/Topic: What orange juice has the most vitamin C? 
Answer/Pointer: According to the Department of Citrus Research Office frozen orange juice concentrate has higher vitamin C content than orange juice in cardboard containers. Some orange juice in cardboard containers is made from concentrate, and that has more Vitamin C than those juices that are not made from concentrate. The relative amounts of Vitamin C in a juice product should be specified on the labels. Some are fortified with additional Vitamin C. You can check to see if the product provides 100%, 130%, or some other amount. The Vitamin C content of fresh juice varies according to when the fruit was picked and the variety of orange. Those oranges picked earlier in the season have more Vitamin C than those picked later in the season. For more complete technical information, see "Seasonal Changes in Florida Oranges" published in 1940 (U.S. Department of Agriculture Technical Bulletin No. 753. Should you want to speak with someone at the Department of Citrus about additional questions, the number for that office is 863 295-5950.
