Lemon oil

Lemon oil suppliers and sourcing guide

Lemon oil is the essential oil from the peel of the lemon, Citrus limon. Most is cold-pressed: the peel is rasped or squeezed during juice processing and the oil is separated from the water by centrifuge. Argentina, Italy and the US are leading origins. Distilled, folded (concentrated) and terpeneless versions are made from it for clear beverages and stronger, more stable flavors.

Forms and grades of lemon oil

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

  • Cold-pressed

    The standard full-bodied lemon oil, mostly limonene, used in beverages, baked goods and confectionery.

  • Distilled

    Steam-distilled oil with a sharper, less fresh profile, often used in colas and clear drinks.

  • Folded

    Concentrated oil (for example 5-fold or 10-fold) with part of the terpenes removed, giving more citral per kilogram.

  • Terpeneless

    Oil with most terpenes removed for clear, alcohol-soluble or water-soluble beverage flavors.

  • Organic

    Certified organic cold-pressed lemon oil, priced separately.

What to check on the COA

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

GC profile
Gas chromatography of limonene, beta-pinene, gamma-terpinene, citral and other markers; chiral and isotope checks are used to screen for added synthetic citral or limonene.
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 calculated as citral, by titration or GC, which drives flavor strength and price.
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

Citral, limonene and evaporation residue vary by origin, season and orchard, and price swings with crop size. Record origin, crop season and aldehyde content per lot, and test pesticide residues where the oil is used undiluted in beverages.

Frequently asked questions

What forms of lemon oil can brands buy?

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

What should the COA for lemon 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 lemon 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. 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.

What is the regulatory status of lemon oil?

21 CFR 182.20 lists lemon (Citrus limon) and lemon peel among essential oils, oleoresins (solvent-free) and natural extractives that are generally recognized as safe (GRAS) for their intended use. FDA's Substances Added to Food inventory lists lemon oil (CAS 8008-56-8) with the technical effect flavoring agent or adjuvant, citing 21 CFR 172.230, 173.240 and 182.20. 21 CFR 173.240 allows isopropyl alcohol in lemon oil as a residue from production of the oil at not more than 6 parts per million.
