Identical Aromas are produced via chemical syntheses such as esterification or acetylation. The required raw materials do not need to be of natural origin, but the chemical texture of the end-product has to be identical to a natural substance of vegetable or animal origin. Accordingly, a large number of nature-identical flavorings are available which can compete in quality and quantity with the natural ones. Nature-identical aromas are, in general, residue-free.
