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.Recommanded Product: Isopentyl hexanoate The following contents are mentioned in the article:
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. This study involved multiple reactions and reactants, such as Isopentyl hexanoate (cas: 2198-61-0Recommanded Product: Isopentyl hexanoate).
Isopentyl hexanoate (cas: 2198-61-0) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Recommanded Product: Isopentyl hexanoate
