Abstract

This invention relates to the use of a salt and/or a mild caustic in solution to increase the relative volatility of aromatics contained in an aqueous stream. The increased relative volatility so achieved enables more efficient concentration of the aromas via distillation. The pH of the aroma-containing aqueous stream does not exceed 7.0 through the addition of the salt or caustic to prevent aroma degradation.
