1. a production has based on dry basis at least about 60 wt%, preferably at least about the method for the peas protein product of the protein content of 90 wt% (N x 6.25), and described method comprises:

  • (a) extract the peas protein source with calcium saline solution, dissolve to cause the peas protein from described protein sources, and form the peas protein aqueous solution;

    (b) at least in part the described peas protein aqueous solution is separated with remaining peas protein source;

    (c) the described peas protein aqueous solution of optional dilution;

    (d) pH to pH that regulates the described peas protein aqueous solution is about 4.4 for about 1.5-, with the peas protein aqueous solution of production acidifying;

    (e) if acidifying peas protein solution is not already to clarify, optional with its clarification;

    (f) alternative as from step (b) to (e), the pH to pH that then optional dilution regulates the peas protein aqueous solution of mixing and remaining peas protein source is about 4.4 for about 1.5-, and the peas protein aqueous solution of described acidifying is separated with remaining peas protein source;

    (g) optional by the concentrated described peas protein aqueous solution of selective film technology, keep simultaneously the ionic strength substantial constant;

    (h) the described concentrated peas protein solution of optionally diafiltration;

    With(i) the optional peas protein solution of described concentrated also optionally diafiltration that makes is dry.
