摘要
试验选用茶树杂交种新选801和新选807制得白茶茶样27个,从萎凋变化规律、审评得分和生化指标3个方面对其进行白茶适制性鉴定。结果表明,2个新品系与对照种福鼎大毫茶一样,会随萎凋时间延长,水浸出物、咖啡碱和茶多酚含量呈下降趋势变化,而氨基酸和可溶性糖含量则呈上升趋势变化。对品种间在审评得分及氨基酸、茶多酚和可溶性糖含量方面的差异作可重复双因素方差分析,结果表明,2个新品系与对照种福鼎大毫茶在感官审评得分、氨基酸、可溶性糖和水浸出物含量方面的差异均达到了极显著水平。新选801、新选807适合付制白茶。
In order to study the white tea processing suitability of Xinxuan 801 and Xinxuan 807,two new tea hy- brid strains,27 white tea samples were produced to analyze the withering rules,organoleptic quality test scores, and biochemical component contents. The results showed that the contents of water extraction, caffeine and polyphenols decreased with the prolonging of withering time, but the soluble sugar and amino acid increased. This experiment compared the contents of water extraction, soluble sugar, polyphenols, amino acid, and the organoleptic test scores a- mong the testing new tea strains based on two-factor variance analysis. These findings suggested that the contents of water extraction, soluble sugar, amino acid, and the organoleptic test scores differed significantly among Xinxuan 801 ,Xinxuan 807 and Fuding Dahaocha. The new tea stains, Xinxuan 801 and Xinxuan 807, are suitable for white tea processing.
