Stable, edible delivery systems for water miscible or water soluble materials, and aqueous food products such as beverages incorporating such delivery systems are provided. The disclosed delivery systems may be used to isolate a substance otherwise having an unacceptable taste in the food product or to protect a sensitive material in the food, e.g., an ingredient prone to degradation. Methods for producing the delivery systems and aqueous dispersions are also disclosed, wherein an acidification agent lowers the pH of the emulsion particles core during and/or after emulsification.
