Abstract
Spearmint flavor enhancers and methods for the production thereof. The spearmint flavor enhancers may include l-carvone, l-carveol isomers, and d-dihydrocarveol isomers. The spearmint flavor enhancers may further include l-isocarveol isomers, l-carvyl acetate isomers, d-dihydrocarvyl acetate isomers, and l-isocarvyl acetate isomers.
Claims15
A method for obtaining a spearmint flavor enhancer comprising the following steps:
- (i) fractionating crude carveol to produce a first plurality of distillation fractions;
- (ii) combining a selected group of one or more of the first plurality of distillation fractions rich in l-carvone, l-carveol, d-dihydrocarveol, and l-isocarveol to produce a mixture;
- (iii) acetylating the mixture to produce an acetylation product;
- (iv) fractionating the acetylation product to produce a second plurality of distillation fractions, and
- (v) combining a selected group of one or more of the second plurality of distillation fractions to obtain said spearmint flavor enhancer,
- wherein said spearmint flavor enhancer shows the following composition:
- (a) about 30 to about 50 percent by weight of l-carvone, and
- (b) about 50 to about 70 percent by weight of l-carvyl acetate isomers,
- on condition that the amounts add, optionally with further constituents, to 100 percent by weight.
