What it is

Key lime juice comes from the Key lime (Citrus aurantiifolia), a small, tart variety of lime native to Southeast Asia but widely grown in Florida and the Caribbean. The juice is extracted by pressing the fruit. It has a distinctively floral, tart flavor, more intense than that of common Persian limes.

Why it's used

Manufacturers use key lime juice primarily as a flavoring agent, adding a bright, tart taste to a variety of foods. It is especially common in desserts like pies, cakes, and ice cream, but can also be found in sauces, marinades, and beverages.

Health notes

Key lime juice is generally recognized as safe (GRAS) by the FDA for use as a food ingredient. It is a source of vitamin C, an essential nutrient. International bodies like JECFA have evaluated citrus juices, but no specific health concerns are associated with the typical levels found in food. Evidence does not suggest adverse effects from consuming key lime juice in normal dietary amounts.

Allergen info

Key lime juice is not derived from any of the 9 FDA major allergens. It does not contain gluten.
