An adsorbent material typically comprising an acid-treated three-layer mineral, such as a smectite clay mineral, having a silica content, expressed as SiO2, of from 90 % to 99.5 % by dry weight, an average pore diameter of 50 to 100 Angstroms, a non-water leachable aluminium content, expressed as Al2O3, of at least 0.05 % and a Hedley acidity of from 0.01 % to 4 % is provided. The adsorbent may be used to improve the haze resistance of aqueous beverages such as beers, wines, fruit extracts or fruit extract-containing beverages. |
