1. A steviol glycoside composition with reduced surface tension, the composition comprising an aqueous solution of:
a steviol glycoside; and
at least 1% by weight of a surface tension reducing compound, the surface tension reducing compound comprising
(i) one or more monocaffeoylquinic acids or salts thereof;
(ii) at least 10% by weight of one or more dicaffeoylquinic acids or salts thereof and
(iii) at least one of an ester of ferulic acid and quinic acid, an ester of sinapic acid and quinic acid, an ester of p-coumaric acid and quinic acid, an ester of caffeic acid and 3-(3,4-dihydroxyphenyl)lactic acid, an ester of caffeic acid and tartaric acid, and isomers thereof,
wherein the aqueous solution comprises a 1:0.5 to 1:4 ratio by weight of steviol glycoside to the surface tension reducing compound.
