摘要：
A process for preparing a soy protein product having a protein content of at least 60% by weight, preferably at least 90% by weight, more preferably at least 100% by weight (N x 6.25) on a basis in dry weight, comprising: (a) (i) the addition of calcium salt or other divalent salt to the precipitation supernatant of a micellar mass of soy protein to provide a conductivity of 2 mS to 30 mS, or (ii) the partial concentration of the precipitation supernatant of the soy protein micellar mass at a concentration of less than 50 g / L and the addition of calcium salt or other divalent salt to the partially concentrated supernatant to provide a conductivity of 2 mS at 30 mS, or (iii) the concentration of the precipitation supernatant of a micellar mass of soy protein at a concentration of 50 g / L to 400 g / L, preferably 100 to 250 g / L, and the addition of salt of calcium or other salt divalent to the supernatant co centered to provide a conductivity of 2 mS to 30 mS, (b) the removal of the precipitate from the resulting solution from step (a) to leave a clear solution, (c) optionally adjust the pH of the clear solution between 1.5 to 4.4, preferably from 2.0 to 4.0, (d) (i), when step (a) (i) has been carried out, the concentration, or (ii) when step (a) (ii) has been carried out, a additional concentration of the clear solution optionally pH adjusted for a protein content of 50 to 400 g / L, preferably 100 to 250 g / L, to provide a clear concentrated soy protein solution, (e) optional diafiltration of the clear concentrated protein solution, and (f) drying the concentrated solution.Un procedimiento de preparación de un producto de proteína de soja que tiene un contenido de proteína de al menos 60% en peso, preferiblemente al menos 90% en peso, más preferiblemente al menos 100% en peso (N x 6.25) en una base en peso seco, que comprende: (a) (i) la adición de sal de calcio u otra sal divalente al sobrenadante de la precipitación de una masa micelar de proteína de soja p
