ABSTRACT:
Bitter substances (isohumulones) are removed from brewers yeast suspensions or brewers yeast autolysates by contacting a yeast suspension or yeast autolysate with a composite adsorbent material containing an adsorbent and magnetic particles embedded in a porous matrix of organic polymeric material having a pore size within the range of 2-30nm, and separating the composite containing isohumulone molecules adsorbed thereto from the suspension or autolysate. The composite may be regenerated by removing the adsorbed isohumulone which can then be recovered.
