摘　　要：本文通过测定苹果液发酵过程中还原糖、pH、酒精度等指标,联合感官评价结果,筛选发酵菌株、接种量、菌种比例,获得较好的苹果发酵液加工工艺。在白地霉和酿酒酵母复配接种情况下,接种量为3%,接种比例1∶8,培养温度为28℃,摇床转速为120r/min时,发酵获得酒精度为6.1%Vol、具有苹果清香气味、酸甜适中、棕黄色有光泽、流动性好、质地均匀、无分层和气泡的苹果发酵液。The article introduces a good apple broth fermentation processing technology,which screens the fermentation strains,level of inoculation and proportion of strains by determining the indicators of the apple broth fermentation process,such as the reducing sugar,the pH value and the alcohol by volume,along with the sensory testing results.A mixed inoculation of Geotrichum candidum and Saccharomyces cerevisiae,which adapts 3%inoculation,an inoculation ratio of 1∶8,a culture temperature of 28℃and a shaking speed of 120r/min,gave the fermented apple broth of 6.1%Vol,and it possesses apple fragrance,moderate sweetness and sourness,lustre in darkyellow,good fluidity and a homogeneous appearance without bubbling or layers.
