FIELD: food industry.;SUBSTANCE: group of inventions relates to the food industry. To produce a proteinaceous product containing legume protein in an amount of at least about 60 % (wt./wt.; N × 6.25) in terms of dry weight, represented by lentils, chick peas or dry peas, is carried out as follows. Method comprises extraction of legumes from a protein source with an aqueous solution of calcium salt to solubilise and form an aqueous protein solution. One separates the water solution of legume protein from the remaining material of the protein source of legumes. Concentration is carried out using a selective membrane of an aqueous solution of legume protein while maintaining substantially constant ionic strength. Concentrated protein solution of beans is diafiltered and the protein solution of beans is dried. Method does not involve a step for adjusting pH. Disclosed is a food composition, which contains a protein product of legumes.;EFFECT: group of inventions provides a product with natural pH, the method is safe and easy.;39 cl, 10 tbl, 9 ex
