RFF#16 – Frozen concentrated orange juice contains 24-55% more vitamin C (when re-constituted) compared to ready-to-drink orange juice

This is largely because with every day of storage, vitamin C levels decrease by about 2%. Nevertheless, this does not necessarily mean that re-constituted juice is better, as the rate of vitamin C degradation may be greater in re-constituted juice. Therefore, the bottom line is, don’t leave juice in your fridge for too long, its benefits will decrease.
