The present invention in its broadest aspect relates to a method for reducing glycoalkaloid content and turbidity of an aqueous phase comprising compounds selected from two or more of PA, PI, PPO, LipO, pectin, lipid, glycoalkaloid and phenolic compounds of which at least one compound is selected from PA, PT, LipO and PPO; a) providing an aqueous phase comprising compounds selected from two or more of PA, PI, PPO, LipO, pectin, lipid, glycoalkaloid and phenolic compounds of which at least one compound is selected from PA, PT, LipO and PPO; and b) performing one or more steps to reduce the concentration of solanine in the dry matter of the aqueous phase with at least 15 percent, such as at least 20%, such as at least 25% and to achieve an optical density at 620 nm of the remaining aqueous phase of less than 0.7; such as less than 0.5; such as less than 0.3; such as less than 0.2; such as less than 0.1; and thereby obtaining an aqueous phase having reduced glycoalkaloid content and turbidity compared to an untreated aqueous phase.
