摘要/Abstract

摘要： 以鄂茶1号茶鲜叶为原料,按照工夫红茶初制工艺,通过检测主要生化成分和挥发性化合物结合感官评审,研究鄂茶1号茶鲜叶红茶的适制性。结果表明,由鄂茶1号制作的红茶的水浸出物、茶多酚、氨基酸和可溶性糖含量分别为47.3%、16.2%、3.2%和3.3%,茶黄素、茶红素和茶褐素含量分别为0.6%、6.1%和7.2%;共鉴定出51种挥发性化合物,其中气味活度值（Odor activity values,OAVs）大于1的香气成分有11种,包括β-紫罗酮、β-大马烯酮、芳樟醇及其氧化产物（2种）、香叶醇、癸醛、壬醛、苯乙醛、辛醛、柠檬烯;滋味醇厚,花果香浓郁,适制高档红茶。

Abstract: Echa No.1 fresh tea leaves were analyzed for the processing suitability for Congou black tea in terms of sensory evaluation, the main biochemical components andβvolatileβcompounds.βTheβresultsβindicatedβthat the contents of water extracts, teaβpolyphenols, free amino acids, and solubleβsugar were 47.3%, 16.2%, 3.2% and 3.3%, respectively. Theβcontentsβof thea?avins, thearubigins andβtheabrownins were 0.6%, 6.1% and 7.2%. The GC/MS results showed that 51 aroma components were identified. Among the compounds identified, there were 11 kinds of aroma components whose OAVs reached over 1, including β-damascenone, β-ionone, linalool and its oxidation products, geraniol, decanal, nonanal, benzeneacetaldehyde, octanal and limonene. The sensory evaluation results showed that the aroma was sweet and floral, and the taste was mellow,Echa No.1 was suitable for processing congou black tea with high quality.
