Rectified oils have been redistilled to improve a particular property or characteristic, such as flavor or aroma. Eor example, natural oil of peppermint is frequently rectified to remove dimethyl sulfide, which has a powerful and objectionable cooked vegetable note deleterious to the use of the oil in cmme de menthe Hqueurs. Distillation is also used to remove psoralens, which are harmful photosensitizing agents present in natural bergamot oil. Color may be removed, eg, from cassia oil, by vacuum steam distillation. A desirable component, such as 1,8-cineole (eucalyptol) 85% in eucalyptus oil, may be...

Artificial bergamot oils are also sold, these being composed, for instance, of triacetin, terpenes and a little bergamot oil such are either used as they are or are employed as diluents of the pure oil.2 Bergamot oil is sometimes diluted also with the black or with the rectified oil referred to above. 

A very deep colour, with high specific gravity, denotes the presence of bergamot black a burnt smell with a low specific gravity and a low proportion of esters,1 indicates the rectified oil.

This process may be conducted in a miniature still built on the same general plan as the large commercial still. The loss in the amount of oil is more than compensated for by the better quality and the increased salability of the rectified oil. 

To reach an oil quality of international commercial standard, the crude oil is generally redistilled. The rectified oil contains about 75% carbonyl compounds (chemical analysis) which correspond to 70-72% citral (GC).

For most purposes the single rectified oil is used and is the one described in the Food Chenticals Codex and is official in many pharmacopoeias. In products where solubility is important, or where a clean peppermint flavor is essential (e.g., CTone de menthe and chocolate fillings), the triple distilled oil is preferred.

The rectified oil confains little or no unpleasant smelling lower aliphatic aldehydes. 

The silicon rectifiers (oil and water-cooled) have longer lives and higher efficiency compared to selenium rectifiers. The oil-cooled types are not susceptible to damage by dust and dirt. They are 20-50% smaller in size than the selenium rectifiers. 

P. is steam-distilled from the partially dried leaves and stems of the - peppermint plant and then further fractionated by steam or vacuum distillation to yield a rectified oil that is free from bitter (menthone) or grassy smells and tastes as well as from residues and traces of water.
