Broken oolong-black tea is an innovative tea in China produced by applying characteristic manufacture crafts of broken oolong tea (bruising) and broken black tea (fermentation) on the manufacture of tea and it has both aroma features of broken oolong tea and broken black tea. The aim of this study is to investigate the differences of the volatile compounds among broken oolong-black, broken oolong and broken black tea made by Huangzhixiang (HZX) and Huangdan (HD) varieties by gas chromatog.-mass spectrometry (GC-MS) combined with chemometirc anal. The results suggested significant differences on both aroma quality and volatile compounds profile of three kinds of tea. Chemometric anal. showed that 47 and 52 differential volatile compounds were identified to distinguish three kinds of teas made by HZX and HD, resp., and the differences of volatile compounds among the tea samples were mostly quant. rather than qual. Besides, compounds with floral and fruity aroma increased in broken oolong-black tea compared with the others, while compounds with green aroma decreased in broken oolong-black tea. Quant. descriptive anal. of the aroma showed that sweet aroma was a new trait of broken oolong-black tea compared with broken oolong tea while green aroma disappeared compared with broken black tea. Our results provide the theor. and practical meaning for the application of two characteristic crafts from different tea manufacture on the innovation of tea manufacture In the experiment, the researchers used many compounds, for example, 5-Hexyldihydrofuran-2(3H)-one (cas: 706-14-9Product Details of 706-14-9).
5-Hexyldihydrofuran-2(3H)-one (cas: 706-14-9) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. 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.Product Details of 706-14-9
