About
Orange oil is the essential oil cold-pressed from the outer peel of the sweet orange (Citrus sinensis (L.) Osbeck), composed predominantly of d-limonene (~90%) together with smaller quantities of linalool, decanal, and other terpenes. It is used widely as a natural flavouring agent in foods, beverages, confectionery, and baked goods to impart a characteristic citrus taste and aroma.
Safety summary
Orange oil is Generally Recognized as Safe (GRAS) at levels used in food flavouring, affirmed by both the FDA (21 CFR 182.20) and the Flavor and Extract Manufacturers Association (FEMA No. 2825); no ADI has been established by JECFA, reflecting its well-accepted safety profile at typical food-use concentrations. At high doses, its primary constituent d-limonene has demonstrated gastrointestinal irritant effects and mild hepatotoxicity in rodent studies, though these are not considered relevant at normal dietary exposure. Individuals with citrus sensitivity, GERD, or IBS should exercise caution, as concentrated citrus oil flavourings may trigger or worsen symptoms.
