Terpeneless Sesquiterpeneless Lime Oil

#### Lime Oil, terpeneless and sesquiterpeneless. Terpeneless, sesquiterpeneless lime oil is prepared from distilled lime oil, rarely from expressed lime oil, by the conventional methods of deterpenation. See **Terpeneless**** ****Oils**, Part One of this work and **Lemon Oil, Terpeneless **and **Sesquiterpeneless, **Part Two of this work. The author would certainly prefer to work with a terpeneless, sesquiterpeneless lime oil from Expressed Lime Oil. The virtually deterpenated lime oil is a pale yellow or almost colorless liquid of a powerful, sweet-fruity, grape-like, somewhat perfumery odor, reminiscent of neroli or terpeneless petitgrain oil on the dryout. The terpeneless fraction constitutes only a very small part of the lime oil, and the terpeneless oil thus becomes quite expensive. The separated terpene fractions find little use in perfumery. They are often mixed with other terpenes under the name of "citrus terpenes", but they also find their way back to lime oil as an adulterant (diluent). The flavor value of lime terpenes is negligible. **Terpeneless, Sesquiterpeneless Lime Oil **is used extensively in flavors, particularly in carbonated beverages where its superior stability, good solubility and richness of body is greatly appreciated. Trace amounts of cyclamal can give very interesting twists to a lime flavor based upon terpeneless lime oil. For hard candy, etc., the natural, distilled lime oil is often preferred for its lower cost and for its greater similarity to the lime-juice + lime- peel flavor picture. In the popular lemon-lime flavor combination for soft drinks, however, a comparatively large proportion of terpeneless, sesquiterpeneless lime oil is needed to produce a pleasant balance, sufficiently different from straight lemon flavor. Recent statistics show that lemon-lime flavor is second in popularity next to cola flavor in the U.S.A. and several other markets. In the cola-type of flavor which is the most popular all over the world, lime is combined with cinnamon, orange and other natural flowers. Terpeneless, sesquiterpeneless lime oil blends excellently with bitter orange oil and it produces interesting modifications in grape, gooseberry, red currant, mandarin, "tutti-frutti" and many other types of fruit flavor. The suggested use level is 0.05 to 0.10 mg% and the Minimum Perceptible is as low as 0.005 to 0.010 mg%. These figures reveal a great flavor power, but they do not tell about the lack of flavor body at this high solution. In this respect, the Expressed Lime Oil is superior.
