Lemon Grass, Oil (cymbopogon Citratus Dc. And Cymbopogon Flexuosusstapf)

Lemongrass oil is an essential oil obtained through steam distillation or expression from the leaves of two Cymbopogon species: Cymbopogon citratus DC. and Cymbopogon flexuosus Stapf. The oil is composed primarily of volatile compounds including citral (geranial and neral), myrcene, and other terpenes that contribute to its characteristic lemon-like aroma and flavor profile. The CAS number 8007-02-1 identifies this ingredient for regulatory and chemical purposes.

Lemongrass oil is used as a flavoring agent in a variety of food and beverage applications. Common uses include flavoring in soft drinks, ready-to-drink beverages, confectionery products, baked goods, dairy products, and seasonings. The oil is also utilized in the preparation of herbal teas and infusions. Due to its natural origin and pleasant sensory characteristics, lemongrass oil has become popular in both conventional and specialty food manufacturing. Typical usage levels range from trace amounts to several hundred parts per million depending on the food category and desired flavor intensity.

Lemongrass oil has been used traditionally in culinary and beverage applications for centuries, particularly in Southeast Asian cuisines. The safety profile of lemongrass oil is generally considered favorable based on its long history of use and available scientific evidence. No adverse events have been reported to the FDA in association with lemongrass oil used as a food flavoring, and no food recalls have been linked to this ingredient.

Toxicological studies conducted on lemongrass oil and its primary components have not identified significant safety concerns at levels used in food flavoring. The European Food Safety Authority (EFSA) has evaluated flavoring substances including lemongrass oil components and established that they are safe at anticipated levels of intake. Acute and subchronic toxicity studies have shown low toxicity profiles in animal models.

Individuals with sensitivities to citral or other terpenes may experience reactions, though such instances are rare. Dermal application of undiluted essential oils may cause irritation in sensitive individuals, but this is not relevant to food additive use where the oil is typically diluted and incorporated into food matrices.

Lemongrass oil is not on the FDA's Generally Recognized as Safe (GRAS) list, meaning it has not undergone formal GRAS notification and approval. However, the absence from the GRAS list does not indicate unsafety; rather, it reflects the regulatory pathway chosen by manufacturers. Many natural flavoring ingredients function under alternative regulatory frameworks. Lemongrass oil is permitted for use as a flavoring agent in the European Union and is listed in the International Organization for Standardization (ISO) standards for essential oils.

Manufacturers using lemongrass oil as a food additive must ensure compliance with FDA regulations for food additives and natural flavor regulations. The ingredient must be sourced from approved botanical origins and processed according to food safety standards including those under the Food Safety Modernization Act (FSMA).

Chemical composition studies have thoroughly characterized lemongrass oil, identifying citral as the predominant active component at levels typically between 70-85%. Antimicrobial and antioxidant properties of lemongrass oil have been documented in scientific literature, though these functional aspects are distinct from its use as a flavoring agent. Toxicological evaluations of citral and lemongrass oil conducted by research institutions and flavor industry organizations have consistently demonstrated safety margins well above anticipated food exposure levels. Long-term consumption studies and epidemiological data from populations with high dietary lemongrass exposure support the historical safety record of this ingredient.
