Characterization of aroma-active compounds and perceptual interaction between esters and sulfur compounds in Xi baijiu was written by Ma, Ning;Yi, Fengping;Zhu, Jiancai. And the article was included in European Food Research and Technology in 2020.Reference of 1795-01-3 This article mentions the following:
The aroma-active compounds of three Xi baijiu samples (Xijiulan, Y1, Xijiuyinxiangguizhou, Y2 and Xijiuyinzhi, Y3) were analyzed by gas chromatog.-olfactometry (GC-O), GC-flame photometric detection (FPD) and odor activity value (OAV). The results indicated that a total of 92 aroma compounds were determined, including 16 sulfur compounds Furthermore, 2-methyl-3-furanthiol (OAV: 31-220), 3-mercapohexyl acetate (OAV: 1870), di-Me trisulfide (OAV: 333-400), 3-mercaptohexanol (OAV: 34-36), β-damascenone (OAV: 1317-1342), 2-butylfuran (OAV: 629-672), Et 3-methylbutanoate (OAV: 655-899), Et hexanoate (OAV: 687-729), and Et octanoate (OAV: 1164-1362) exhibited much higher OAVs and aroma intensities (AIs) than other compounds Finally, the perceptual interactions between five sulfur compounds and six esters were studied using Feller’s additive model in Y2. Among the 30 binary mixtures, 12 groups showed an additive effect, 4 groups exhibited a synergistic effect, and 14 groups exerted a masking effect. These data indicated that di-Me disulfide and 2-methyl-3-furanthiol had masking and additive effects on the aroma of esters. In the experiment, the researchers used many compounds, for example, 3-Ethylthiophene (cas: 1795-01-3Reference of 1795-01-3).
3-Ethylthiophene (cas: 1795-01-3) belongs to benzothiophene derivatives. Benzothiophene is a fused ring compound of thiophene ring and benzene ring, which is an important class of heterocycles with advantageous structures. It is found within the chemical structures of pharmaceutical drugs such as raloxifene, zileuton, sertaconazole, and also BTCP.Reference of 1795-01-3
