1. A method of obtaining a product from legume protein having a protein content based on dry weight (N × 6.25) of at least 60 wt.%, Preferably at least 90 wt.%, Which contains: (a) source extraction treatment legume protein with an aqueous solution of calcium salt, optionally containing an antioxidant, in order to solubilize the legume protein from the protein source and form an aqueous legume protein solution； (b) at least partially separate the legume protein aqueous solution from the residues of the legume protein source； (c) P If necessary, dilute an aqueous solution of legume protein； (d) adjust the pH of an aqueous solution of legume protein to a value of 1.5 to 4.4 to obtain an acidified aqueous solution of legume protein； (e) if necessary, lighten the acidified solution of legume protein, if it is is not transparent； (f) as an option for steps (b) through (e), if necessary, diluting and then adjusting the pH of the combined aqueous legume protein solution and the remainder of the legume protein source to a value of from 1.5 to 4.4, after which office for an acidified aqueous solution of legume protein from legumes of a legume protein source； (g) if necessary, a concentrated aqueous solution of legume protein while maintaining its ionic strength substantially constant through the use of membrane-selective technology； (h) if necessary, diafiltration of a concentrated solution of legume protein and ( i) if necessary, drying a concentrated and, if necessary, diafiltered bean protein solution. 2. The method according to claim 1, characterized in that said aqueous solution of feces salt1.
