Abstract: This disclosure sets forth bubble modifiers capable of reducing mean bubble diameter of a gasified aqueous solution, e.g., a carbonated beverage. The bubble modifier may include one or more compounds selected from the group consisting of monocaffeoylquinic acids, dicaffeoylquinic acids, monoferuloylquinic acids, diferuloylquinic acids, monocoumaroylquinic acids, dicoumaroylquinic acids, and salts thereof. The bubble modifier desirably comprises less than 0.3% (wt) of malonate, malonic acid, oxalate, oxalic acid, lactate, lactic acid, succinate, succinic acid, malate, or malic acid; or less than 0.05% (wt) of pyruvate, pyruvic acid, fumarate, fumaric acid, tartrate, tartaric acid, sorbate, sorbic acid, acetate, or acetic acid; or less than about 0.05% (wt) of chlorophyll; or less than about 0.1% (wt) of furans, furan-containing chemicals, theobromine, theophylline, or trigonelline.
