Superior sourness, unrivaled stability Acidulants provide sourness and freshness in otherwise overly sweet-tasting candy. However, adding an acidulant to reach the desired sourness can trigger sugar inversion during candy production, which can result in undesired stickiness and deformation. Acids can also effect other ingredients like gelatin degradation or color destabilization. Corbion supplies a range of buffered acid solutions under its proven PURAC® brand that provide much needed stability alongside sourness you desire.
