Tag: Natural citric acid sources

Over two million tons of citric acid are produced globally each year, primarily for its use as an acidifier and preservative in the food industry. While a manufactured version is ubiquitous in packaged goods, naturally occurring citric acid is found in a wide variety of foods. Knowing what foods are high in citric acid can help those managing dietary restrictions or seeking to increase their intake for health reasons, such as preventing kidney stones.

Lemons and limes contain some of the highest concentrations of naturally occurring citric acid, which can make up as much as 8% of their dry weight. However, this versatile compound is found in many other products, both in nature and as a manufactured food additive.
