1. A method of obtaining a protein product from legumes containing protein in an amount of at least about 60% (weight / mass； N × 6.25) based on dry weight, which includes: (a) extracting the legume protein from an aqueous salt solution calcium, so that the solubilization of the legume protein takes place and an aqueous solution of the legume protein is formed； (b) the separation of the legume protein aqueous solution from the rest of the legume protein source； (c) optional concentration using a selective membrane of the legume protein solution x while maintaining substantially constant ionic strength； (d) optionally diafiltering the concentrated optional protein solution legumes and (e) optionally drying the optionally concentrated and optionally diafiltered protein solution bobovyh.2. The method of claim 1, wherein said calcium salt is calcium chloride. The method of claim 2, wherein said calcium chloride solution has a concentration of less than about 1.0 M. The method of claim 3, wherein said calcium chloride solution has a concentration of at least about 0.10 to about 0.15 M. The method according to claim 1, wherein said extraction step is carried out at a temperature of from about 15 to about 65 ° C. The method of claim 5, wherein the temperature is from about 20 to about 35 ° C. The method of claim 1, wherein said extraction step is carried out at a pH of from about 4.5 to about 11.8. The method of claim 7, wherein said pH is from about 5 to about 7.9. The method according to claim 1, wherein the concentration of beige in said aqueous solution of legume protein is from about 5 to about 50 g / l. The method of claim 9, wherein the protein concentration in said aqueous legume protein solution is from about 10 to about 50 g / l. Way1.
