| LIME OIL Usage And Synthesis |
| Description | Refer to LIME JUICE, DEHYDRATED. | | Chemical Properties | Obtained by expression from the fresh peel or the crushed whole fruit | | Chemical Properties | The oil is prepared from the sour juice obtained by expression of the whole fruit. The oil can be separated from the
juice by centrifugation. | | Chemical Properties | Cold-pressed lime oils are produced by two different mechanical processes:
The whole fruits are chopped and the resulting oil–juice emulsion is subsequently centrifuged to yield the oil of the so-called type-A quality.
Alternatively, the oil of the so-called type-B quality is obtained by rasping
and/or squeezing the peels of the fruits as described on p. 195. During
type-A process, the liberated oil comes into contact with the highly acidic
juice, which may cause some changes in the chemical composition.Thus, the
sensory properties (“juicy”) of type-A oils are closer to those of distilled oils.
Pressed lime oils are yellow to greenish-yellow to green liquids with a
strong, characteristic odor, reminiscent of lemon.
d2020 0.875–0.884/0.880–0.888; n20D 1.482–1.486/1.484-1.488; α20D +35 ° to +41 °/(not def.); carbonyl value 16-31/18-35, corresponding to a
calculated content of citral of 4.5–8.5%/5–9.5%; evaporation residue:
10-14.5%/13-19%; CD value ≥18.2/≥23.6 (data for Mexican oils of type A/type B).
d2020 0.861–0.879; n20D 1.476–1.486; α20D +38 ° to +53 °; solubility: 1 vol in
≤3 vol 95% ethanol; evaporation residue: 5–12%; CD value ≥0.24 (data for
cold-pressed Persian lime oils).
The composition and uses of pressed lime oil are similar
to those of pressed lemon oil. As in lemon oil, the main constituents are
terpene hydrocarbons such as limonene, β-pinene and γ-terpinene. Generally,
neral (1–2.5%) and geranial (2–3.7%) are present in a somewhat higher
concentration. The same is true for furocoumarins; therefore, the quantities
of cold-pressed lime oil, which may be used in perfume compositions, are
limited. Lime oils of type A are mainly used to create juicy lime notes in
soft drinks; oils of type B are mainly used for producing fresh citric notes in
perfume compositions. | | Occurrence | Found in the peel of the fruit Citrus aurantifolia Swingle, formerly classified as Citrus medica L., var acida Brandis | | Uses | lime oil (Citrus acida, Citrus aurantifolia) has similar properties and uses as lemon oil. Lime oil is extracted from lime skin by cold pressure or distillation. | | Preparation | By expression from the fresh peel of the fruit. | | Definition | Extractives and their physically modified derivatives. Citrus aurantiifolia, Citrus. | | Essential oil composition | The main constituents of the oil are d-limonene, α-pinene, dipentene, C8, C9, and C10 aldehydes and
citral. The oils are rectified under vacuum to remove terpenes in order to improve solubility and permit use for flavoring carbonated
beverages. | | Taste threshold values | Taste characteristics at 30 ppm + 0.075% citric acid and 5% sugar: juicy lime with a sweet, fresh, candy
nuance | | Taste threshold values | Taste characteristics at 50 ppm with 5% sugar: juicy, characteristic lime with a fresh, sweet pulpy note. | | Safety Profile | A skin irritant.
Questionable carcinogen with experimental
tumorigenic data. Mutation data reported.
When heated to decomposition it emits
acrid smoke and irritating fumes. |
