An aqueous solution of a pulse protein product having a protein content of at least about 60 wt% (N x 6.25) d.b. which is soluble in aqueous media at a pH of less than about 4.4 and heat stable at that pH range is adjusted in pH to a pH of about 6 to about 8. The resulting product is further processed by drying the product, recovering and drying any precipitated pulse protein material, heat treating and then drying the product, or heat treating the product and recovering and drying any precipitated pulse protein material.本發明係關於一種具有至少約60 wt%(N×6.25)d.b.之蛋白質含量之豆類植物蛋白質產品的水溶液，該蛋白質產品可溶於pH小於約4.4之水介質中且在該pH範圍熱穩定，pH經調整至pH約6至約8。所得產品如下進一步處理：乾燥該產品、回收且乾燥任何沈澱之豆類植物蛋白質材料、熱處理且接著乾燥該產品，或熱處理該產品且回收及乾燥任何沈澱之豆類植物蛋白質材料。
