What is it?
Potato protein is a plant-based protein, produced together with the potato starch from starch potatoes.
Potato proteins are found in powder-form and have a high protein content (78%).
In the process of extracting starch from potatoes, a protein-rich juice is produced. The proteins are then concentrated, purified and dried.
Potato proteins contain essential amino-acids in much higher proportions than many cereals-based proteins or proteins from animal origins.
Where and Why is it used?
The amino-acids that potato proteins contain perform essential functions in the body, such as supporting the body’s metabolism and lowering blood pressure. Potato proteins have many functional properties, they dissolve in water, absorb fat and have foaming abilities to add air bubbles in baked goods.
Potato protein offers superior emulsifying, foaming and gelling properties. They have shown to be able to substitute high-value animal proteins like caseinate, whey protein isolate, gelatine, egg albumen (egg white) and egg yolk, in various confectionery products, meat and meat analogues, non-dairy cheese, toppings and ice creams, and egg-free dressings. Also, excellent gluten-free bakery goods can be achieved. Potato protein is also a replacement for aquafaba, or chickpea/garbanzo water for vegan meringues or macarons.
