摘要: 采用不同的光照强度进行单枞茶鲜叶的晒青, 用气相色谱—质谱法分析其对茶香气成分的影响, 研究结果表明: 以波长大于520 nm, 光照强度为13 725~16 774 lx的光波进行晒青30 min, 制得的毛茶含有的芳香物质种类较多, 独具β - 紫罗酮、紫罗兰酮, 表现为香气浓郁, 品质较佳。

Abstract: Five different light intensities were employed in the withering process of Dancong tea. The analysis results of aromatic constituents with GC-MS are as follows: The fresh leaves withered by different light intensities resulted in different qualities of semi-made teas in terms of aromatic constituents. While the wave-length of the light was ≥ 520 nm, the light intensities 13 725 - 16 774 lx, withered the tea for 30 min, the corresponding semi2made tea had many sorts of aroma substances, contained β-Ionone and Ionone emitting unique sweet aroma of flower and smelled good and had better quality.
