Sorbic acid is widely used as a preservative in foods and beverages. A common problem when using sorbic acid in beverage applications is low solubility in syrups and finished beverages. Because of its low solubility sorbic add is unstable in syrups and finished beverages resulting in creaming and precipitates. For example the solubility of sorbic acid in water at room temperature is 0.16 wt%. It is desired to have at least 1200 1600 ppm sorbic acid in syrups and at least 200 250 ppm in finished beverages but such amounts have been difficult to achieve due to low solubility creaming settling precipitation and phase separation.
