The present work describes the relationship between volatile aroma components and flavors of Fenghuang Dancong tea. Volatile aroma components of five types of Fenghuang Dancong tea namely Baxian, Milanxiang, Yulanxiang, Guihuaxiang, and Yinhuaxiang were extracted by headspace solid-phase microextraction (HS-SPME), then analyzed by gas chromatog.- mass spectrometry (GC-MS) technique and gas chromatog. olfactometry (GC-O) techniques. The GC-MS results showed that a total of 116 volatile components were detected, among which 21 (including alcs., esters, olefins, aldehydes, ketones, and alkanes) were commonly detected in all types of tea. Based on GC-O anal., 26 active ingredients that mainly contribute to grassy, sweet, floral, fruity, woody, and honey aromas were detected. Among these ingredients, four compounds including linalool oxide I, linalool, nerol, and neroli, which give floral, sweet, and honey aromas were abundant (with high aroma intensity) in all five types of tea. This suggests that these compounds are the main components contributing to the unique aroma of Fenghuang Dancong tea. In the experiment, the researchers used many compounds, for example, 5-Ethyldihydrofuran-2(3H)-one (cas: 695-06-7Recommanded Product: 695-06-7).
5-Ethyldihydrofuran-2(3H)-one (cas: 695-06-7) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. 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: 695-06-7
