Which type of fruit is citric acid primarily derived from?

Citric acid is primarily derived from citrus fruits, which include oranges, lemons, limes, and grapefruits. These fruits contain higher concentrations of citric acid compared to other types of fruits. The acidity from citric acid not only contributes to the tart flavor of these fruits but also has significant applications in food preservation, flavor enhancement, and cosmetic formulations. Understanding the source of citric acid is essential, especially in advanced esthetics, as this ingredient is often used in skincare products for its exfoliating and pH-balancing properties. While other fruits, such as berries and grapes, may contain some citric acid, they do not have the same levels as citrus fruits. Melons, on the other hand, typically have low acidity and are not a source of citric acid. This makes citrus fruits the definitive source for this important acid in both dietary and cosmetic contexts.
