摘要: 为了探究冷冻工艺对红茶品质的影响,改进红茶的品质,本文试验设定冷冻工艺流程处理。结果表明:只有冷冻工艺处理样的茶多酚、氨基酸等主要化学成分含量有增加趋势,咖啡碱和可溶性糖的含量减少不显著。感官审评结果亦表明,冷冻工艺处理样的红茶香气纯正,品质最优。

Abstract: In order to explore the influence of freezing process on the black tea quality and to improve the quality of black tea, the experiment on the freezing treatment during the processing of black tea was conducted. The results showed that the contents of tea polyphenols, amino acids and other major chemical components were increased in the freezing treatment, but the contents of caffeine and soluble sugar showed a slight reduction. The results of sensory evaluation also showed that the freezing processing products of black tea aroma is pure, with best quality.
