Citric acid is a versatile acidifier that lowers pH and enhances flavour balance in a wide range of preparations. Commonly used in confectionery such as fruit jellies and sucking candies, it also serves as a pH corrector and can replace tartaric acid in baking powders. Highly soluble in water and easily soluble in ethanol, it helps regulate water activity while boosting the antioxidant effect of ascorbic acid and remaining readily assimilated by the body.
