CHEMICAL STRUCTURE
stake R80

Delta LACTONES, which naturally occur in many kinds of foods, are indispensable for creating various flavor and fragrance compounds.

Many flavor and fragrance components have chiral structures, which show optical activity, and well-known that the odor quality of optically active substances is much superior to that of racemic compounds.

Zeon has successfully developed the synthetic process of manufacturing the optically active stake and commercially launched two types of enantiomers R-body and S-body.
Using the optically active stake in compounds makes it possible to reproduce really natural flavors and fragrances that have been impossible to create only with racemic compounds.
