摘要
为探索不同产地对岳西翠兰品质的影响,以岳西县冶溪镇石咀村、菖蒲镇长岭村、毛尖山乡红旗村、姚河乡梯岭村、头陀镇虎形村和姚河乡龙王村 6 个乡镇的群体种一芽二叶鲜叶为原料,采用相同工艺加工成岳西翠兰,进行理化检测和感官品质分析.结果表明,岳西翠兰整体内含成分比较丰富,特别是游离氨基酸含量整体比较高;6 个产地中姚河乡龙王村和头陀镇虎形村的岳西翠兰感官评分较高.由各品质成分相对含量建立了偏最小二乘法判别分析模型成功区分 6 个产地的岳西翠兰样品并筛选到 4种关键成分,分别是咖啡碱,儿茶素(catechin,C)、表儿茶素(epicatechin,EC)、没食子儿茶素(gallocatechin,GC),可作为区分 6个产地岳西翠兰的品质指标.本研究结果将为岳西翠兰加工工艺和品质提升提供一定的科学参考.
Abstract
To explore the influence of different production areas on the quality of Yuexi Cuilan,using one-bud,two-leaf fresh leaves from six townships in Yuexi County,namely Shizui Village in Yexi Town,Changling Village in Changpu Town,Hongqi Village in Maojianshan Township,Tiling Village in Yaohe Township,Huxing Village in Toutuo Town,and Longwang Village in Yaohe Township.These leaves were processed into Yuexi Cuilan using the same technique,followed by physicochemical testing and sensory quality analysis.The results showed that Yuexi Cuilan had a rich overall composition,with particularly high levels of free amino acids.;Yuexi Cuilan from Longwang Village in Yaohe Township and Huxing Village in Toutuo Town has a higher sensory score among the six production areas.A partial least squares discriminant analysis model was established based on the relative content of various quality components,successfully distinguishing Yuexi Cuilan samples from six production areas.These four key components were identified,namely caffeine,catechin(C),epicatechin(EC),and gallocatechin(GC),which can be used as quality indicators to distinguish Yuexi Cuilan samples from six production areas.The results of this study will provide scientific guidance for improving the processing technology and quality of Yuexi Cuilan.
