What does from concentrate mean?

Ever wondered what it means when you buy breakfast juice and it says, from concentrate or not from concentrate???

From concentrate- to make from concentrate the fruit is picked, squeezed and the resulting juice concentrated in the country of origin. The concentrated juice is shipped to the country of use for packing. The juice is then reconstituted, restoring it to its original strength by adding the same amount of water.

Not from concentrate- this juice comes directly from the fruit. It is picked and processed within 24hours to retain the freshness. The juice is packed without the addition of water and then pasteurised, just like milk to retain its freshness.

Hope this is useful!
