Lemons

Lemons are tart, yellow citrus fruits that grow on evergreen trees. They are a natural source of citric acid and vitamin C. The juice and zest are commonly used for flavoring.

Lemons are used to add a bright, tart flavor to a wide variety of foods and beverages. They can also act as a natural preservative by lowering pH, and the juice can help prevent browning in fruits and vegetables. They are found in dressings, marinades, baked goods, desserts, and drinks.

Lemons are widely recognized as safe (GRAS) by the FDA for use as a flavoring agent. They are a good source of vitamin C, an antioxidant important for immune function. While generally considered healthy, consuming large amounts of lemon juice may erode tooth enamel due to its acidity. International bodies like JECFA and EFSA have evaluated citric acid, a component of lemons, and established safety guidelines.
