ALLYLCYCLOHEXANE ACETATE

Chemical properties

Colorless liquid, almost insoluble in water, miscible with alcohol, essential oils and flavor chemicals, perfume materials, etc. Pronounced “mixed-fruity“ odor, sweet, lasting and less ethereal than the lower aliphatic acetates. The flavor is overall fruity (“tutti-frutti”) with some resemblance to Pineapple, Peach and Apricot.

Occurrence

Has apparently not been reported to occur in nature.

Preparation

By esterfication of cyclohexane, acetic acid and allyl alcohol in the presence of benzene

Taste threshold values

Taste characteristics at 15 ppm: pineapple with a sweet, ripe, fruity nuance.

Metabolism

The hydrolysis of ester linkages in foreign compounds may be catalysed by many different esterases; most of these have a low degree of substrate specificity and they are to be found in all animals and bacteria (Parke, 1968). In the rat, allyl acetate and allyl alcohol are metabolized to 3-hydroxypropylmercapturic acid, which is excreted in the urine (Clapp, Kaye & Young, 1969). In dogs, cyclohexylacetic acid was not aromatized and was probably completely oxidized in the body by β-oxidation (Bernhard, 1937; Williams, 1959).
