摘要:

利用明胶指数法、卵清蛋白沉淀法、十二烷基硫酸钠-聚丙烯酰胺凝胶电泳、福林-肖卡法、蛋白沉淀法测定24 个红葡萄酒酒样中呈涩物质的含量,并与感官评价的涩感强度进行对比分析。结果表明,蛋白沉淀测定单宁的方法与感官评价结果的涩感强度相关性最好,且该方法操作简单,适合在酒厂进行推广。

关键词: 红葡萄酒, 涩感强度, 评价, 呈涩物质

Abstract:

A total of 24 red wine samples were analyzed by gelatin index, ovalbumin index, sodium dodecyl sulphate
polyacrylamide gel electrophoresis (SDS-PAGE), Folin-Ciocalteau, and protein precipitation methods, respectively. The
results obtained with these methods were compared with the perceived astringency. The protein precipitation assay showed a
strong correlation with the perceived astringency, which was convenient and suitable for extensive applications in wineries.

Key words: red wine, astringency intensity, evaluation, astringent taste compound
