Essential Oil Properties and Characteristics
Orange essential oil is a rich yellow-orange to dark-orange-coloured mobile liquid with a sweet, fresh citrus odour, distinctly reminiscent of the odour from a scratched orange peel.
Origin and History
There are numerous varieties of sweet orange such as Navel, Jaffa and Valencia. It is a smaller tree than the bitter orange tree, less hardy and with a few or no spines and the fruits are smaller with a sweet pulp and non-bitter membrane.
Sweet orange is extensively used in food flavouring. The d-limonene serves as an important starting material for the synthesis of l-carvone, an important source of synthetic spearmint flavour. The price of l-carvone from sweet orange oil is usually two-thirds the cost of spearmint.
The therapeutic properties of orange were first recognised in ancient China, where the dried peel had been used for centuries to treat coughs, colds and anorexia.
Method of Extraction
Sweet orange essential oil is cold-pressed from the ripe or almost ripe outer peel of the orange fruit.
Precautions During Use (Contraindications)
Sweet orange oil is non-toxic, non-irritating and non-sensitising. The oil is not considered to be phototoxic. However, bitter orange oil has a distinct phototoxic effect.
Orange essential oil is a strengthening, refreshing, strengthening and stimulating essential oil.
