    Abstract: It has unexpectedly been found that a low alcohol or alcohol-free beverage, with a flavor profile very close to a beer of at least 4% (vol/vol) alcohol, can be produced by using Pichia kluyveri yeast strains. In particular, Pichia kluyveri yeast strains only use the glucose in the wort, and have the ability of converting this substrate into a high concentration of specific flavor compounds, which are normally produced by Saccharomyces ssp. yeast strains used for the brewing of beer. In this way the Pichia kluyveri yeast strains can be used to produce either a low alcohol or alcohol-free beverage, depending on the glucose levels in the wort. The main flavor compounds produced by Pichia kluyveri in the fermentation of wort are isoamyl acetate, isoamyl alcohol, ethyl butyrate, ethyl hexanoate and ethyl octanoate.

    Abstract translation: 意外地发现,通过使用毕赤酵母酵母菌株可以生产具有非常接近至少4%(vol / vol)醇的啤酒的风味特征的低醇或无酒精饮料。 特别地,毕赤酵母酵母菌株仅使用麦芽汁中的葡萄糖,并且具有将该底物转化为高浓度的特异性风味化合物的能力,其通常由酵母菌(Saccharomyces ssp)产生。 用于酿造啤酒的酵母菌株。 以这种方式,根据麦芽汁中的葡萄糖水平,毕赤酵母酵母菌株可用于产生低醇或无酒精饮料。 在发酵麦芽汁中由毕赤酵母生产的主要风味化合物是乙酸异戊酯,异戊醇,丁酸乙酯,己酸乙酯和辛酸乙酯。
