摘要 本文以华夏酿酒有限公司2004年度赤霞珠为试材,研究了美洲、欧洲和欧美三种类型橡木桶陈酿对黄烷-3-醇和原花色素含量及组成的影响。结果表明,橡木桶陈酿过程中,(-)-表儿茶素((-)-epicatechin,EC)、(-)-表儿茶素没食子酸酯((-)-epicatechingallate,ECG)、(-)-表棓儿茶素没食子酸酯((-)-epgallocatechingallate,EGCG)含量上升,(+)-儿茶素((+)-catechin,CAT)保持相对稳定,而(-)-表棓儿茶素((-)-epigallocatechin,EGC)略有下降。原花色素含量下降,平均聚合度降低。不同类型的橡木桶对两者含量的影响不同。 The wine made by Huaxia winery Co. Ltd. in 2004 was used as raw material to study the changes of flavan-3-ols and proanthocyanidins during aging in American oak, Europen oak, or Occident oak barrel. After the aging in the oak barrel, the concentration of (-)-epicatechin (EC), (-)-epicatechin gallate (ECG), and (-)-epigallocatechin gallate (EGCG) increased, whereas that of (-)-epigailocatechin (EGC) slightly decreased. The content and mean degree of polymerization (mDP) of proanthocyanidins decreased, and the composition changed accordingly.
