The invention relates to the field of food ingredients. In particular, it relates to methods for providing highly purified coagulated potato protein having a desirable taste which is advantageously used for the fortification of food products. Provided is a method for providing a purified coagulated potato protein product, comprising (i) subjecting heat coagulated potato protein to one or more extraction step(s) with an alcoholic extraction solvent comprising (a) ethanol and water at a ratio in the range of 90:10 to 60:40 (v/v), or (b) propanol and water at a ratio in the range of 90:10 to 40:60 (v/v) at a pH in the range of 3 to 6, under conditions allowing for extraction of glycoalkaloids and lipids from said heat coagulated potato protein composition, followed by (ii) washing the extracted heat coagulated potato protein with water to obtain a purified coagulated potato protein product, followed by (iii) drying the purified coagulated potato protein product.
