Citric acid is found naturally in some fruits and vegetables and in many processed foods as an additive. Citric acid is responsible for the tart taste of lemons and many soft drinks.

Citric acid is found naturally in citrus fruits, notably lemons, oranges and limes. It is also found in kiwi fruit, some berries and vegetables, such as broccoli, bell peppers and Brussels sprouts.

It is used to enhance the flavor of tart pie fillings and prepared fruit juices. Citric acid is used in many processed foods, such as gelatins and candies, to modulate acidity and also as a preservative in many food items.

Outside the food industry, citric acid is found in cleaning products to aid in cutting grease and lime.
