The present invention discloses a method for purifying a vegetable protein material, when eliminating ribonucleic acids, phytic acid, and the phytates of the protein material; a vegetable protein material suspension is formed with a pH of between 3 and 6; the protein material suspension is treated with an acid phosphatase enzyme and optionally another enzyme phytase, at a temperature and for enough time to degrade the ribonucleic acids, and optionally the phytic acid, and the phytates of the protein material; subsequently, the suspension treated with enzyme is washed in order to eliminate the degraded materials.
