Caution
Citric acid is obtained from citrus fruits, and Sodium Citrate is a salt of citric acid. It has antioxidant and preservation characteristics and is generally used to adjust the pH level of a product. It also extends the shelf life of the products by neutralising metal ions in the formula and preventing microbial development, resulting in items that are safer and last longer.
