Orange oil is an essential oil produced by cells within the rind of an orange fruit (Citrus sinensis fruit). In contrast to most essential oils, it is extracted as a by-product of orange juice production by centrifugation, producing a cold-pressed oil. It is composed of mostly (greater than 90%) d-limonene and is often used in place of pure d-limonene. D-limonene can be extracted from the oil by distillation.
Brazil has the largest production of fresh oranges and also it processes more orange than any other country making it the largest producer of orange oil.
