Abstract
The invention relates to a process for native potato protein isolation, to native potato protein isolates, to the use thereof, and to a food product comprising a native potato protein isolate. The invention provides a novel isolation process for obtaining highly pure native potato protein isolates having a glycoalkaloid concentration of less than 150 ppm.
Claims14
Process for obtaining a native potato protein isolate comprising patatin and protease inhibitor, comprising
- i) subjecting potato fruit juice to a flocculation by a divalent metal cation at a pH of 7-9;
- ii) centrifuging the flocculated potato fruit juice, thereby forming a supernatant;
- iii) subjecting the supernatant to expanded bed adsorption chromatography operated at a pH of less than 11 and a temperature of 5-35° C. using an adsorbent capable of binding potato protein, thereby adsorbing native potato protein to the adsorbent;
- and
- iv) eluting at least one native potato protein isolate from the adsorbent with an eluent.
