武夷名丛‘白鸡冠’适制性研究

Suitability of Wuyi Mingcong Baijiguan forTea Processing

  • 摘要: 为探讨武夷名丛‘白鸡冠’品种的茶类适制性,提高其加工利用价值,促进地方优良茶树种质资源的应用推广,本研究以白鸡冠茶树一芽二叶鲜叶为试验材料,以‘福鼎大白茶’为对照,制成白茶、绿茶,分析样品感官品质和生化成分的差异。结果表明:白鸡冠制成的白茶、绿茶均表现出滋味鲜爽的品质特征,感官综合品质较优,表现出良好的白茶、绿茶适制性。白鸡冠绿茶中表没食子儿茶素(EGC)、表儿茶素(EC)、表没食子儿茶素没食子酸酯(EGCG)、表儿茶素没食子酸酯(ECG)、儿茶素(C)、茶氨酸含量均显著高于白鸡冠白茶,白鸡冠白茶和绿茶中没食子酸和咖啡碱的含量均低于对照福鼎大白的白茶和绿茶。

     

    Abstract:  Suitability of utilizingleaves from Wuyi Mingcong Baijiguan (Camellia sinensis) for processing teas was explored to extend the commercial valueof the newly cultivated variety. Fresh leaves plucked from the tea bushes wereprocessed into white as well as green tea. The chemical composition and sensoryquality of the tea samples were assessed and compared with Fuding Dabaicha (Camellia sinensis). The results indicated that both experimental green and whiteteas had desirable refreshing sensory quality with high marketing potential.Chemically, the green tea was significantly higher in the contents of teapolyphenols, such as EGC, EC, EGCG, ECG and catechin, and theanine than thewhite tea. On the other hand, the teas made from the Baijiguan leaves werelower on gallic acid and caffeine than Fudingdabai green or white teas. Itappeared that Wuyi Mingcong Baijiguan could be an additional resource to be cultivated for green and/orwhite tea production.
