The present invention is directed to non-soy oilseed protein products, very low in, or free of, beany, green, vegetable or similar flavour notes and useful for the fortification of food and beverage products and prepared without the use of salt in the process. The non-soy oilseed protein products of the present invention are obtained by extracting non-soy oilseed protein source with water to form an aqueous non-soy oilseed protein solution, at least partially separating the aqueous non-soy oilseed protein solution from residual non-soy oilseed protein source, adjusting the pH of the aqueous non-soy oilseed protein solution to a pH between about 1.5 and a value about 1 pH unit lower than the typical pH of isoelectric precipitation to solubilize the bulk of the protein and form an acidified non-soy oilseed protein solution then separating the acidified non-soy oilseed protein solution from the acid insoluble solid material. The acidified non-soy oilseed protein solution may be dried following optional concentration and diafiltration to form a non-soy oilseed protein product, which may be an isolate. The acid insoluble solid material may be washed with acidified water and then dried to form another non-soy oilseed protein product. These products may be dried at the acidic pH at which they were prepared or may be adjusted in pH before drying.本發明係關於非大豆含油種子蛋白產品，其具有極少豆腥、生青、蔬菜或類似風味特徵或不含該等特徵，且可用於食品及飲料產品之營養強化，且在製備製程中不使用鹽。本發明之該等非大豆含油種子蛋白產品係藉由以下獲得：用水提取非大豆含油種子蛋白質來源以形成非大豆含油種子蛋白質水溶液，使該非大豆含油種子蛋白質水溶液與剩餘非大豆含油種子蛋白質來源至少部分地分離，將該非大豆含油種子蛋白質水溶液之pH調節至介於約1.5與較等電沈澱之典型pH低約1個pH單位之值之間的pH，以溶解大部分蛋白質並形成酸化非大豆含油種子蛋白質溶液，然後使該酸化非大豆含油種子蛋白質溶液與酸不溶性固體材料分離。可在可選濃縮及滲濾之後乾燥該酸化非大豆含油種子蛋白質溶液，以形成非大豆含油種子蛋白產品，該產品可為分離物。可用酸化水洗滌該酸不溶性固體材料且然後加以乾燥以形成另一非大豆含油種子蛋白產品。該等產品可在製備其之酸性pH下乾燥或可在乾燥前調節pH。
