Citric acid is found naturally in several fruits and berries, and is commonly added to many foods and beverages as a preservative or for flavor. It has a tart taste, and is also known as lemon salt or sour salt. Many of our customers use our citric acid to clean dishwashers and dishes, or to make fizzy bath bombs (fun!). Citric acid is completely natural, produced by cells during the Krebs cycle.
