Dill (anethum Graveolens L.)

Dill (Anethum graveolens L.) is an herbaceous plant native to southwestern Asia and the Mediterranean region. The culinary additive is derived from the dried or fresh leaves (dill weed) and seeds of the plant. Dill is recognized for its distinctive aromatic profile, featuring notes of anise and citrus with subtle pepper undertones. The additive identified by CAS Number 977050-60-4 represents dill in its various processed forms used within the food industry.

Dill is widely used as a flavoring agent in numerous food applications. Common uses include:

- Pickled vegetables (cucumbers, onions, peppers)

- Salad dressings and vinaigrettes

- Fish and seafood preparations

- Cheese and dairy products

- Bread and baked goods

- Cured meats and processed meat products

- Soups and broths

- Condiments and sauces

The herb functions both as a whole ingredient and in extract form, allowing manufacturers flexibility in application methods. Dill seed is often used in pickling brines, while dill weed serves fresh or dried applications in lighter dishes.

Dill has been used in food preparations for centuries across multiple cultures, establishing a long history of safe consumption. As a botanical ingredient derived from culinary herbs, dill presents a favorable safety profile when used at levels typical in food applications.

The FDA has received zero adverse event reports associated with dill consumption through its adverse event reporting system. Additionally, no FDA recalls have been issued for products containing dill as a flavoring agent. This absence of reported safety concerns aligns with dill's status as a traditional food ingredient.

The essential oil and volatile compounds in dill, including limonene and anethole, have been extensively studied. These compounds are present in dill at concentrations far below levels demonstrated to cause adverse effects in toxicological studies. The European Food Safety Authority (EFSA) has evaluated dill flavoring in food applications and maintains its acceptance as a food flavoring substance.

No genotoxicity, reproductive toxicity, or developmental toxicity concerns have been identified in available scientific literature at food-use levels. Individuals with allergies to plants in the Apiaceae family (which includes dill, fennel, celery, and parsnips) may experience cross-reactivity, though such allergies are relatively uncommon in the general population.

While dill does not hold FDA GRAS (Generally Recognized As Safe) status as an additive, this does not indicate a safety concern. GRAS status applies specifically to substances meeting particular regulatory definitions. Dill's long history as a culinary ingredient and its recognition as a traditional food flavoring in most jurisdictions establishes its acceptable use in food.

Dill is approved for use as a flavoring substance in the European Union under Regulation (EC) No 1334/2008 on flavorings. In the United States, dill is permitted for use as a spice and seasoning in various food applications under FDA regulations governing food ingredients. The herb is listed among acceptable food additives in numerous countries and food safety jurisdictions worldwide.

Scientific evaluation of dill has focused on its chemical composition and safety profile. Research has characterized the volatile oil composition, identifying compounds such as d-limonene (30-40%), α-phellandrene, and anethole as primary constituents depending on growing conditions and harvest timing.

Toxicological studies on dill essential oil in animal models have established high safety margins at food-use concentrations. Studies examining the traditional use patterns across populations consuming dill regularly have not identified adverse health outcomes.

Chemical composition studies confirm that dill contains no known toxic compounds at levels relevant to food use. The herb's antimicrobial and antioxidant properties, identified in research contexts, have contributed to its traditional culinary applications and food preservation practices.
