glucosides. Glycoconjugation of geraniol in grapes is a process that reduces the flavor impact of this compound in wine, not only because geraniol is an important flavor component of some wines but also because the rate of formation of other flavor compounds from geraniol during bottle-aging is reduced. However, when flavor compounds such as beta-damascenone are formed in competition with flavorless

香叶醇的糖缀合过程可降低该化合物在葡萄酒中的风味影响,不仅因为
香叶醇是某些葡萄酒的重要风味成分,而且还因为降低了瓶装陈年过程中
香叶醇形成其他风味化合物的速率。但是,当通过多元醇的酸催化
