The initial volume of the foam may be less than about 20% of the volume of the liquid beverage. The foam-maintaining system may comprise octenylsuccinic acid modified starch, and at least one surface active agent selected from the group consisting of acyl lactylate salts, proteins, protein hydrolysates, sucrose esters, and mixtures thereof. |
