The isolation and characterization of a group of odorless and non-volatile glycosides from extracted hops (hop solids which have been previously extracted with non-polar solvents) is disclosed. These glycosides are water soluble and consist of a group of aromatic compounds conjugated to mono-, di-, and trisaccharides. These glycosides are responsible for the formation of kettle hop flavor and taste through both chemical and biological transformations. When these glycosides are transformed, they yield an essence and flavorant which imparts a kettle hop flavor and taste when the essence and flavorant is added to an unhopped beer. These kettle hop flavor essences and flavorants provide economy, consistency, flexibility, quality, and convenience to the brewing process because only one unhopped wort is required to brew a stock of unhopped beer. The unhopped beer can then be dosed with the desired amount of kettle hop flavor essence and flavorant.
本发明公开了从萃取酒花(之前用非极性溶剂萃取过的酒花固体)中分离出的一组无味、不挥发的苷类化合物及其特征。这些苷是
水溶性的,由一组与
单糖、二糖和三糖共轭的芳香族化合物组成。通过
化学和
生物转化,这些苷可形成
水壶啤酒花的风味和口感。当这些糖苷发生转化时,就会产生一种香精和调味剂,当把这种香精和调味剂加入未加料的啤酒中时,就会产生
水壶酒花的风味和口感。这些酒花香精和调味剂为啤酒酿造过程提供了经济性、一致性、灵活性、质量和便利性,因为只需要一种未加料麦汁就可以酿造出未加料啤酒。然后就可以在未加料啤酒中添加所需量的啤酒花香精和调味剂。
