All juices of the Biotta Classic range have been pasteurised for preservation purposes. This however does not mean that the juices contain no vitamins and minerals. The longer and the higher the period of pasteurisation, the more harmful it is for vitamins. Biotta's gentle process, which preserves most of the nutrients, heats the juice rapidly and cools it rapidly down again. The production process is carried out in a minimum number of steps. Oxygen is largely kept out of the process, preventing oxidation and thus the loss of vitamins.
