Orange oil

Orange oil suppliers and sourcing guide

Orange oil is the essential oil pressed from the peel of the sweet orange, Citrus sinensis, recovered as a co-product of orange juice processing. Brazil and the US (Florida) dominate supply. Cold-pressed oil is mostly d-limonene and is used as is or concentrated by folding and terpene removal. Orange essence oil, recovered from juice during evaporation, is a separate, juicier-smelling product.

Forms and grades of orange oil

Suppliers sell different products under the same name. Specify the one you need.

  • Cold-pressed

    Standard sweet orange oil, high in d-limonene, for beverages, confectionery and bakery.

  • Folded

    Concentrated oil (for example 5-fold to 20-fold) with more aldehydes per kilogram and better stability.

  • Terpeneless

    Oil with most terpenes removed for clear beverages and emulsions.

  • Orange essence oil

    Oil recovered from juice evaporation, with a fresh-juice character.

  • Organic

    Certified organic cold-pressed orange oil.

What to check on the COA

Compare each result with your own specification when the lot arrives.

GC profile
Gas chromatography of limonene, myrcene, decanal, octanal, linalool and other markers against the specification.
Physical constants
Specific gravity, refractive index and optical rotation at a stated temperature, compared with the supplier's specification or the Food Chemicals Codex monograph where one exists.
Aldehyde content
Total aldehydes as decanal, by titration or GC, the main grading value for orange oils.
Appearance and odor
Color, clarity and odor against a retained standard; off-notes often show up before the GC profile shifts.
Heavy metals
Lead and arsenic, typically by ICP-MS, against the supplier's specification.

Storage, lots and expiry

Storage and shelf life

Citrus peel oils oxidize quickly once opened, so store them cool (often refrigerated), dark and in full containers, and nitrogen-flush partly used drums. Cold-pressed oils can drop a waxy sediment in the cold, which is normal and can be decanted or filtered. Shelf life is set by the supplier's specification, commonly shorter for cold-pressed than for folded or terpeneless oils, and aged stock should be retested for peroxide value and odor.

Lots and expiry dates

Aldehyde content and color change with fruit variety, season and juice plant, and price follows the orange crop. Record origin, season and aldehydes per lot, and test for pesticide residues if the oil is used at high levels.

Frequently asked questions

What forms of orange oil can brands buy?

Common forms include cold-pressed, folded, terpeneless, orange essence oil and organic. Ask each supplier for the specification sheet of the exact grade they quote.

What should the COA for orange oil include?

Expect gC profile, physical constants, aldehyde content, appearance and odor and heavy metals, each with its method, specification and result for that lot.

How should orange oil be stored?

Citrus peel oils oxidize quickly once opened, so store them cool (often refrigerated), dark and in full containers, and nitrogen-flush partly used drums. Cold-pressed oils can drop a waxy sediment in the cold, which is normal and can be decanted or filtered.
