摘要：
A process for preparing a soy protein product that has a protein content of at least 60% by weight (N x 6.25) on a dry weight basis, comprising: (a) extracting a source of soy protein to solubilize the soy protein in the source material and to form an aqueous soy protein solution having a pH of 5 to 7, (b) optionally subjecting the aqueous soy protein solution to a color removal stage, (c) concentrate the aqueous soy protein solution at a concentration of 50 to 400 g / L, (d) optionally diafiltrate the concentrated soy protein solution to form a concentrated and optionally diafiltered soy protein solution, (e) optionally treat the concentrated soy protein solution and optionally diafiltered with an adsorbent to remove color and / or odor compounds, (f) optionally subjecting said concentrated soy protein solution and optionally diafiltered to a Pasteurization step by heating the solution at a temperature of 55 ° to 70 ° C for 30 seconds up to 60 minutes, and, optionally, cooling the pasteurized solution at a temperature of 25 ° to 40 ° C for further processing, (g) (i) acidifying the solution concentrated and optionally diafiltered soy protein optionally pasteurized at a pH of 2.0 to 4.0 and drying the soy protein solution, or (ii) diluting the concentrated soy protein solution and optionally diafiltered in cold water having a temperature of less than 15 ° C to cause the formation of soy protein micelles, allow the protein micelles to combine into a micellar mass of soy protein, separate the micellar mass of soy protein from the supernatant, acidify the separated micellar mass of protein at a pH from 2.0 to 4.0, and dry the acidified separated soy protein micellar mass.Un proceso para preparar un producto proteínico de soja que tiene un contenido de proteína de al menos 60% en peso (N x 6.25) sobre una base de peso seco, que comprende: (a) extraer una fuente de proteína de soja para solubilizar la proteína de soja en el material de origen y para formar una solución d
