目的:探索湖南农业大学长安教学基地湘妃翠、碧香早和茗丰3个品种制成的黑毛茶经冠突散囊菌发花后其呈味品质成分的差异变化,对黑毛茶进行冠突散囊菌发花优化实验。方法采用国标检测方法对发花前黑毛茶及发花后成品茶其水浸出物、茶多酚、游离氨基酸、可溶性糖等呈味成分进行分析,对所测数据进行组间和组内方差分析。结果湘妃翠经发花后其水浸出物、茶多酚、游离氨基酸和生物碱在发花成品茶中下降幅度最大;碧香早经发花后其成品茶中茶多酚、游离氨基酸与其原料茶相比显著下降;茗丰经发花后其茶多酚、氨基酸和生物碱与其原料茶相比显著下降,而可溶性多糖显著增加。结论在三个发花成品茶中,以湘妃翠化学品质表现最为突出,湘妃翠较碧香早、茗丰更适制发花黑茶,其次为茗丰。
目的:探索湖南農業大學長安教學基地湘妃翠、碧香早和茗豐3箇品種製成的黑毛茶經冠突散囊菌髮花後其呈味品質成分的差異變化,對黑毛茶進行冠突散囊菌髮花優化實驗。方法採用國標檢測方法對髮花前黑毛茶及髮花後成品茶其水浸齣物、茶多酚、遊離氨基痠、可溶性糖等呈味成分進行分析,對所測數據進行組間和組內方差分析。結果湘妃翠經髮花後其水浸齣物、茶多酚、遊離氨基痠和生物堿在髮花成品茶中下降幅度最大;碧香早經髮花後其成品茶中茶多酚、遊離氨基痠與其原料茶相比顯著下降;茗豐經髮花後其茶多酚、氨基痠和生物堿與其原料茶相比顯著下降,而可溶性多糖顯著增加。結論在三箇髮花成品茶中,以湘妃翠化學品質錶現最為突齣,湘妃翠較碧香早、茗豐更適製髮花黑茶,其次為茗豐。

Objective To explore the changes of quality tasting ingredients of different tea of primary dark tea fermented by Eurotium cristatum fungus, using Xiangfeicui, Bixiangzao and Mingfeng as 3 kinds of tea cultivars primary dark tea as raw materials for Eurotium cristatum fungus growing by the best optimization fermentation conditions. Methods The content of water extract, tea polyphenols, free amino acids, soluble sugar and others tasting compositions of each kinds of primary dark tea and their fermented end-products were detected by the national standard test methods, then their inter- and intra-groups variances were analyzed by ANOVA. Results The content of water extract, tea polyphenols, free amino acids and alkaloid in Xiangfeicui primary dark tea had the most notable transformation and declined in its fermented end-products comparing with the primary dark tea. The content of tea polyphenols, free amino acids in Bixiangzao fermented end-products had a significant declined compared with its primary dark tea. The content of tea polyphenols, free amino acids and alkaloid in Mingfeng fermented end-products had a significant declined compared with its primary dark tea, while the soluble sugar had a significant increased. Conclusion The most outstanding chemical qualities in fermented end-products were using Xiangfeicui cultivar primary dark tea as material for Eurotium cristatum fermentation in these 3 tea cultivars. Xiangfeicui cultivar is the best choice for primary dark tea fermentation, and Mingfeng cultivar has better quality for fermentation by Eurotium cristatum and obtains good quality fermented end-products.
