An industrial method for the production of a protein-containing food is disclosed. The method includes providing a plant proteinous starting material comprising at least one protein, at least one sugar and at least one phytate. The method also includes extracting with about a neutral or an alkaline aqueous solution at least a fraction of the protein, at least a fraction of the sugar and at least a fraction of the phytate from the starting material to form at least one protein-containing extract and at least one residual plant material. The method also includes separating the extract from the residual plant material to form at least one separated extract containing extracted protein, extracted sugar and extracted phytate. The method also includes purifying the extracted protein in the separated extract by separating it from extracted sugar and extracted phytate by means of an ultrafiltration membrane with a MWCO of at least about 25,000 Dalton to form a purified protein-containing retentate and sugar- and phytate-containing permeate. The method also includes further purifying the protein of the purified protein-containing retentate by washing with an aqueous solution to form a further purified protein-containing stream and a wash solution. The method also includesincorporating the further purified protein-containing stream in a food. The food is characterized by at least one of: at least one of the extract during the separating and the aqueous solution is maintained at pH of between about pI+0.5 and about pI + 2.5, wherein pI is the isoelectric point of the protein and at least one of the extract during the and the aqueous solution comprises a complexant of calcium cation. A food derived from a proteinous starting material comprising at least one protein, at least one sugar and at least one phytate, the food further comprising at least about 70 percent of the protein of the starting material and less than about 60 percent of the phytate of the starting material is also disclosed.
