Cold pressed bitter orange oil is a mobile liquid of dark yellow to olive-yellow or pale brownish yellow color.
The odor is very peculiar, fresh and yet bitter in the sense of dry, but with a rich and lasting, sweet undertone. There are notes which remind of bergamot, grapefruit and sweet orange, but overall, the odor is distinctly different from that of other citrus oils. It is a different type of freshness, a peculiar floral undertone which occasionally shows indolic notes, and a comparatively good tenacity.
Bitter Orange Oil is used extensively in flavors where it forms the main ingredient in the orange sec or triple sec liqueur flavors, and also acts as an important modifier and intensifier in common sweet-orange flavors for soft drinks.
For perfumes, the bitter orange oil finds use among the other citrus oils in all types of colognes, chypres, fougères, fresh fragrances, topnotes, aldehydic citrus bases, etc., and it is one of the most common ingredients in artificial bergamot oil.
Bitter orange oil is frequently adulterated with citrus oil terpenes, distilled oils of bitter orange, sweet orange, grapefruit, etc., or with d-limonene.
After expression of the oil by hand or by machine, some producers submit the peels to steam distillation, thus obtaining a further, small yield of a very poor oil.
