When compared to not-from-concentrate juices, the actual concentrated forms of similar fruit juices provide equal nutritional content. However, much like dried fruit, one serving size of non diluted concentrate juice compared to an equal serving size of not from concentrate juice will greatly differ in nutritional content.
When fresh fruit gets dried, it loses all of its natural water content, shrinking in size. This process works identical in fruit juices as well. The natural state of freshly squeezed fruit juice contains far more water weight volume than that of a concentrated comparison. Consequently, one cup of non diluted concentrate juice will contain purely sugars and nutrients found within the fruit, while the same serving size of bottled juice varieties will contain only a fraction of those same nutrients.
Most concentrated juices get used to make diluted juices. The main objective of juice concentration involves saving time, money and space.
