A method for obtaining at least one or a plurality of recyclable materials from a native material quantity containing phytic acid or phytate, wherein the at least one recyclable material is a phytic acid product, in particular phytic acid and/or at least one phytate, with the following steps: - Step A: Supplying of a native material quantity containing phytic acid and/or phytate from seeds containing phytic acid with hard, breakable shells, in particular from rape fruits, in particular as material quantity from the whole seeds or from seeds that have already been (partially) de-oiled, in particular as expeller meal or as press cake left over as residue from oil extraction, in particular with a press, - Step B: If the material quantity from step A has not yet been comminuted: comminution of the material quantity, wherein at any rate the shells are broken open; - Step C: Dispersal of the comminuted material quantity from step A) or B) with water or with an aqueous solution, wherein preferably up to 8 parts maximum, particularly preferably up to 6 parts maximum, in particular 5 parts maximum of water are added to one part of comminuted material quantity and wherein the water and the comminuted material quantity are stirred so as to give rise to a flowable mash or a dispersion; - Step D): Adjustment of the pH value of the mash from step C) in an alkaline range of pH > 9.5; - Step E): Addition of a water-soluble organic solvent, preferably a water-soluble alcohol, in particular ethanol, preferably in diluted form, to the mash D), in particular subsequently to the adjustment of the pH of the mash in step D); in particular in such a way that an alcohol concentration is reached that is less than 30% in order to detach the shells from the endosperm of the seeds/fruits; - Step F1): Separation of a solid phase, which has the predominant fraction of the shells, from the mash from step E), preferably in a centrifuge in the centrifugal field; - Step F2): Isolation of phytic acid or of a phytate from the solid phase of step F1). - Step A: Supplying of a native material quantity containing phytic acid and/or phytate from seeds containing phytic acid with hard, breakable shells, in particular from rape fruits, in particular as material quantity from the whole seeds or from seeds that have already been (partially) de-oiled, in particular as expeller meal or as press cake left over as residue from oil extraction, in particular with a press, - Step B: If the material quantity from step A has not yet been comminuted: comminution of the material quantity, wherein at any rate the shells are broken open; - Step C: Dispersal of the comminuted material quantity from step A) or B) with water or with an aqueous solution, wherein preferably up to 8 parts maximum, particularly preferably up to 6 parts maximum, in particular 5 parts maximum of water are added to one part of comminuted material quantity and wherein the water and the comminuted material quantity are stirred so as to give rise to a flowable mash or a dispersion; - Step D): Adjustment of the pH value of the mash from step C) in an alkaline range of pH > 9.5; - Step E): Addition of a water-soluble organic solvent, preferably a water-soluble alcohol, in particular ethanol, preferably in diluted form, to the mash D), in particular subsequently to the adjustment of the pH of the mash in step D); in particular in such a way that an alcohol concentration is reached that is less than 30% in order to detach the shells from the endosperm of the seeds/fruits; - Step F1): Separation of a solid phase, which has the predominant fraction of the shells, from the mash from step E), preferably in a centrifuge in the centrifugal field; - Step F2): Isolation of phytic acid or of a phytate from the solid phase of step F1).
