Celery Seed, Oil (apium Graveolens L.)

Celery seed oil (CAS Number 8015-90-5) is an essential oil extracted from the seeds of Apium graveolens L., the common celery plant. The oil is obtained through steam distillation, cold pressing, or solvent extraction of dried celery seeds. It contains volatile aromatic compounds including limonene, β-selinene, and other terpenes that contribute to its characteristic celery aroma and flavor profile. As a natural botanical extract, celery seed oil represents one category of flavoring agents derived from plant sources rather than synthetic chemical synthesis.

Celery seed oil is used primarily in the food and beverage industry as a flavoring agent to provide authentic celery taste to processed foods. Common applications include seasoning blends, soups, broths, sauces, meat products, vegetable preparations, and savory snacks. The ingredient also functions as a solvent or vehicle for other flavor compounds, helping to distribute and stabilize flavor molecules in food formulations. Its dual functionality makes it valuable in food manufacturing where both flavor delivery and product stability are important considerations. Typical usage levels are relatively small—often less than 0.1% by weight—due to the concentrated nature of essential oils.

Celery seed oil has a long history of use in food flavoring with no documented adverse events reported to the FDA. The FDA database contains zero adverse event reports and zero recalls associated with this ingredient, indicating a favorable safety profile in actual food use. Celery seed itself has been used as a culinary spice and food ingredient for centuries across various cultures, providing historical evidence of safe consumption at typical food levels.

As a natural product, celery seed oil's composition can vary based on growing conditions, harvest timing, and extraction methods. Individual components like limonene are generally recognized as safe flavoring agents by regulatory bodies. However, like all essential oils, celery seed oil is concentrated and intended for use at very low levels in finished food products, not for direct consumption.

Potential considerations include that some individuals with celery allergies may react to celery seed oil, though allergic reactions to celery are relatively uncommon. Additionally, celery and related plants contain psoralens, photosensitizing compounds, though the levels in celery seed oil used in food are considered insignificant for food safety purposes.

Celery seed oil does not hold FDA GRAS (Generally Recognized As Safe) status, meaning it has not undergone the formal GRAS affirmation process. However, the lack of GRAS status does not indicate safety concerns; rather, it reflects that manufacturers have not submitted a formal GRAS petition for regulatory review. Many flavoring agents function in food without explicit GRAS designation, operating under the broad category of "flavoring substances" permitted in food under FDA regulations (21 CFR 182.60), which allows for use of flavoring agents derived from plants when used in traditional food preparation methods.

The European Food Safety Authority (EFSA) has evaluated celery seed oil and related celery products as food flavoring ingredients, and these are listed in the European Union's Register of Flavoring Substances used in or on foodstuffs.

Limited peer-reviewed research specifically addresses celery seed oil safety in food applications. Most relevant data comes from general essential oil safety literature and celery plant toxicology studies. The primary safety data supporting celery seed oil's use derives from its long historical use in food flavoring, documented absence of adverse events, and the known safety profiles of its constituent compounds. Botanical composition analyses confirm that celery seed oil contains compounds common to many culinary herbs and spices.

Research on whole celery and celery seed has focused on nutritional properties rather than safety concerns at food-use levels. The concentration of potentially bioactive compounds in the oil is further reduced through dilution in finished food products, resulting in negligible exposure from typical food consumption.
