This juice, thanks to the gentle temperature treatment, retains the complex of vitamins and minerals found in fresh vegetables. This concentrated juice is frozen or poured into special containers, which allows it to be stored without loss of quality and properties for several months, as well as to transport it over any distance. Once at the plant, the concentrated juice goes through a recovery stage – purified water is added to it in the same proportion in which it was originally in it.
