Citric acid is a sequestrant because it has the ability to tie up metal ions and prevent their catalytic effects. This is important in food preservation because metal ions can cause oxidation reactions and spoilage. Therefore, citric acid is commonly used in foods as a preservative to extend their shelf life. Citric acid does not neutralize bases or complex oxygen, and while it may help keep some foods moist, this is not its principal function as a sequestrant.
