摘要: 以湖南省15个有代表性的茯砖茶产品为研究对象,采用同时蒸馏萃取法(SDE)结合GC-MS分析其香气成分;并通过感官审评和化学成分分析,研究了湖南茯砖茶的品质特征和香气组分上的差异。感官审评结果表明,茯砖茶香气以菌香为主要特点,部分茯砖茶稍带沤味、烟气、欠纯正。GC-MS分析结果表明,香气物质含量最多的为醇类(15个样品平均相对含量为23.01%),其次为酸类(18.85%)、酮类(11.10%)、醛类(9.20%)、酯类(4.28%)、碳氢化合物(3.78%)、其他类(2.67%)、杂氧化合物(1.06%),酚类物质(0.07%)的含量最低。茯砖茶主要化学成分含量测定结果表明,15个样品的平均相对含量,茶多酚为10.88%、氨基酸0.66%、咖啡碱3.83%、可溶性糖7.27%、水浸出物31.19%。

Abstract: The variations of quality characteristics and aroma components in 15 typical Hunan Fu brick teas were studied by combined simultaneous distillation and extraction (SDE) and GC-MS techniques, sensory evaluation and chemical analysis. Results of sensory evaluation indicated that the main feature of Fu brick tea was fungus fragrance. Some Fu brick teas had a slight taste of retting and smoke, and were not pure enough. GC-MS analysis showed that the alcohol content was the highest (23.01%), followed by acids (18.8%) Ketones (11.10%), aldehydes (9.20%), esters (4.28%), hydrocarbons (3.78%), other categories (2.67%), phenols (0.07) and heterocyclic oxygen compounds (1.06%). Moreover, the main chemical components of Fu brick tea included polyphenols (averagely 10.88%), amino acids (0.66%), caffeine (3.83%), soluble sugar (7.27%) and water extract (31.19%).
