Oranges, like other citrus fruits, are well-known for their high vitamin C content. However, a common question is whether the vitamin C content in oranges changes after they have been picked. This article delves into this topic, providing a comprehensive analysis based on available research.

Vitamin C, also known as ascorbic acid, is a crucial nutrient that plays a significant role in various bodily functions, including immune function and collagen synthesis. Oranges are a popular source of this essential vitamin.
Post-Harvest Changes in Vitamin C Content
The hypothesis that the amount of vitamin C in oranges decreases after being picked is based on the idea that the fruit is no longer receiving nutrients from its parent plant². However, the results of various experiments have not consistently supported this hypothesis.
In one experiment, the amount of vitamin C present in Naval Oranges was tested at various intervals after being picked. The results showed that the levels of vitamin C increased and decreased, but not at a steady rate. In other words, while the levels did change, there was no specific pattern present in the results.
Another study suggested that oranges do not lose vitamin C after being picked, but they may lose vitamin C when the skin is removed or when the oranges are squeezed to make orange juice³⁴.
Factors Influencing Vitamin C Content
Several factors can influence the vitamin C content in oranges after they have been picked. These include the ripeness of the oranges at the time of picking, the storage conditions, and the length of time since picking.
The vitamin C content in oranges does not consistently decrease or increase after the fruit has been picked. Various factors can influence the vitamin C levels, and more research is needed to fully understand these dynamics. Therefore, while it is clear that oranges are a good source of vitamin C, the exact amount may vary based on post-harvest conditions.
