The combination of solid phase microextraction (SPME) and gas chromatograph-mass spectrometer (GC-MS) is frequently used for comprehensive anal. of aroma components in foods because it can be used to easily analyze volatile components, allowing saving of the amount of solvent used. In this study, SPME-GC-MS anal. of sake samples before and after sherry cask storage was performed to investigate the special flavor derived from sherry cask storage. A GC column with polyethylene glycol as the stationary phase, which is the first choice for volatile component anal., was used. However, the peak of the acid having a carbonyl group was tailed due to its bond with the hydroxyl group of the stationary phase. In the anal. of sake samples, a large and tailing peak derived from the large amount of fatty acids in Japanese sake was observed Addnl., it was not possible to analyze other co-eluting components. To overcome this problem, a novel extraction condition was examined using SPME and tris (hydroxymethyl) aminomethane (Tris). By adding Tris solution to sake, the fatty acid peak was removed successfully, thereby facilitating anal. of the peaks of compounds co-eluting with fatty acids and comprehensive anal. of the aroma components in sake. Furthermore, a comparative anal. of sake before and after storage in sherry cask showed that levels of fatty alcs., organic acid esters, fatty acid esters, and terpenes increased significantly after storage in sherry cask, suggesting that these ingredients might constitute the special flavor of sherry cask-stored sake. 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 are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. 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
