Potato protein is considered a plant-based protein source and is often used in food and beverage applications as a functional ingredient. It is valued for its nutritional profile, as it is rich in essential amino acids, including lysine, threonine, and leucine. It is also low in fat and cholesterol-free. Due to its functional properties, potato protein can be utilized as a thickening agent, emulsifier, or texturizer in food products. It can enhance the texture, moisture retention, and binding properties of various foods, including vegetarian and vegan alternatives. Potato protein is often used in the production of meat substitutes, such as veggie burgers or sausages, to improve their texture and increase their protein content.
