Ylang-ylang, Oil (cananga Odorata Hook. F. And Thomas)

Ylang-ylang oil (CAS Number 8006-81-3) is an essential oil derived from the flowers of Cananga odorata Hook. F. and Thomas, a tree native to tropical regions of Southeast Asia, particularly Indonesia and the Philippines. The name "ylang-ylang" comes from the Tagalog word meaning "flower of flowers." The oil is obtained through steam distillation of the fresh flowers and consists of complex volatile organic compounds including benzyl acetate, linalool, and other terpenes and esters.

In the food industry, ylang-ylang oil functions as a flavoring agent or flavoring adjuvant, primarily used in beverages, confectionery, baked goods, and other processed foods. It contributes floral, fruity, and slightly spicy flavor notes that appeal to consumers seeking exotic or natural flavor profiles. The oil is also widely used in cosmetics, fragrances, and traditional medicine applications outside the food sector.

Typical usage levels in food are generally low, typically ranging from parts per million (ppm) concentrations, as the oil's potent aromatic compounds mean only small amounts are needed to achieve desired flavor effects.

Ylang-ylang oil has been used in food and beverage applications for centuries in its native regions and has a long history of use in traditional contexts. According to available FDA data, there have been no reported adverse events or recalls associated with ylang-ylang oil in food products.

The primary safety consideration for essential oils like ylang-ylang relates to their composition and concentration. When used as a food flavoring at typical levels, the oil undergoes significant dilution, which substantially reduces potential exposure to individual volatile components. Some studies on ylang-ylang oil constituents, particularly at high concentrations used in other applications, suggest potential skin sensitization in sensitive individuals, though this concern is largely relevant to cosmetic or topical applications rather than food use at normal dietary exposure levels.

The European Food Safety Authority (EFSA) and other regulatory bodies have evaluated various components found in ylang-ylang oil, and constituent compounds like linalool and benzyl acetate appear on lists of flavoring substances with established safety profiles.

Ylang-ylang oil is not currently designated as Generally Recognized as Safe (GRAS) by the FDA for food use, meaning it has not undergone the formal GRAS notification process. However, this designation does not necessarily indicate a safety concern; rather, it reflects that the substance may not have met the specific procedural requirements for GRAS status or that such a petition has not been formally submitted.

In the European Union, ylang-ylang oil and related botanical extracts are evaluated under the Novel Foods or Flavoring Substances regulations depending on their intended use and processing method. Various constituents of ylang-ylang oil are listed in the FEMA (Flavor and Extract Manufacturers Association) GRAS list, indicating recognition of safety when used as flavoring components.

The additive remains available for use in food applications in many countries, though regulatory status may vary by region and specific food application.

While extensive clinical safety studies specifically focused on ylang-ylang oil as a food additive are limited, the safety profile of the oil and its constituent compounds has been examined in various contexts. Research on individual components such as linalool demonstrates low toxicity at food-use concentrations. Traditional use data from Southeast Asia, where ylang-ylang flowers and their derivatives have been consumed for extended periods, provides additional evidence of safety at typical exposure levels.

Further research specifically examining ylang-ylang oil's safety profile in food applications would provide additional data to support regulatory determinations, though the absence of reported adverse events and recalls suggests a favorable safety history in current use.
