The invention provides a method for treating rootor tuber juice, comprising a) a pretreatment of the rootor tuber juice to remove rootor tuber lipids to a level below 28 g/kg dry weight; b) cooling the rootor tuber juice to a temperature of ?0.3? C. to ?16? C. to form ice crystals; and c) separating the ice crystals from the rootor tuber juice to obtain, as a first rootor tuber juice product, a concentrated rootor tuber juice. In addition, the invention provides methods to obtain protein depleted rootor tuber juice products, as well as products comprising rootor tuber free amino acids, and uses thereof.
