An aqueous papain solution having improved storage stability for preventing cold turbidity in beer is prepared by dissolving sodium metabisulphite in water, adjusting the pH with sodium hydroxide to about 4.85, adding papain to obtain a turbid solution, clarifying the turbid solution and adding sucrose while stirring. The papain solution contains by weight 20 to 60% sucrose, 1.5 to 3% sodium metabisulphite and 1 to 35% papain. |
