Distilled liquors are important products, both culturally and economically. Chem., as a complex mixture, distilled liquor comprises various chem. compounds in addition to ethanol. However, the chem. components of distilled liquors are still insufficiently understood and compositional differences and similarities of distilled liquors from different cultures have never been compared. For the first time, both volatile organic compounds (VOCs) and non-VOCs in distilled liquors were profiled using mass spectrometry-based metabolomic approaches. A total of 879 VOCs and 268 non-VOCs were detected in 24 distilled liquors including six typical Chinese baijiu and 18 typical Western liquors. Principal component anal. and a correlation network revealed important insights into the compositional differences and similarities of the distilled liquors that were assessed. Et esters, a few benzene derivatives, and alcs. were shared by most distilled liquors assessed, suggesting their important contribution to the common flavor and mouthfeel of distilled liquors. Sugars and esters formed by fatty alc. differ significantly between the assessed Chinese baijiu and Western liquors, and are potential marker compounds that could be used for their discrimination. Factors contributing to the differences in chem. composition are proposed. Our results improve our understanding of the chem. components of distilled liquors, which may contribute to more rigorous quality control of alc. beverages.
Metabolites published new progress about Alcoholic beverages. 123-29-5 belongs to class esters-buliding-blocks, name is Ethyl nonanoate, and the molecular formula is C11H22O2, Safety of Ethyl nonanoate.
