Abstract: The present invention is directed to processes for producing pulse protein products, very low in, or substantially free of, pea/vegetable flavour notes useful for the fortification of food and beverage products and prepared without the use of salt in the process. The pulse protein products are obtained by extracting pulse protein source with water to form an aqueous pulse protein solution, at least partially separating the aqueous pulse protein solution from residual pulse protein source, adjusting the pH of the aqueous pulse protein solution to a pH of about 1.5 to about 3.4 to solubilize the bulk of the protein and forming an acidified pulse protein solution then separating the acidified pulse protein solution from the acid insoluble solid material. Also described is the preparation of an acid soluble protein product and which provides acidic solutions of improved clarity and is derived from the acidified pulse protein solution.
