What it is

Key West lemon juice is the juice from Key limes, a variety of lime native to South Florida. It is known for its distinct tart and aromatic flavor, often considered more intense than common Persian limes.

Why it's used

Manufacturers add Key West lemon juice primarily for its bright, tart flavor. It is used to enhance the taste of seafood, marinades, dressings, and baked goods. Its acidity also helps to preserve foods and can act as a tenderizer in marinades.

Health notes

Key West lemon juice is generally recognized as safe (GRAS) by the FDA when used as a flavoring agent. It is a source of vitamin C, an essential nutrient. International bodies like JECFA have evaluated citric acid, the primary acid in lemon juice, and established acceptable daily intake levels. Evidence does not suggest adverse health effects from typical consumption as a food ingredient.

Allergen info

Not a major allergen. Key West lemon juice is derived from fruit and does not contain any of the nine FDA major allergens or gluten.
