摘　　要：[Objective] The paper was to compare the quality of apple vinegars prepared by different methods and screen an optimum brewing method for apple vinegar production. [Methed] The quality of apple vinegar brewed by three traditional brewing methods and a new method developed by our previous work was analyzed. Three traditional methods were solid state fermentation （SSF）, liquid state fermentation （LSF） and immobilized microorganism fermentation （IMF）, and the new method was multi-microorganisms co-immobilization technology（MMCT）, which used co-immobilized beads of ethanol-producing yeast, aroma-improving yeast and lactic acid bacteria （with a ratio of 6：3：1） for alcoholic fermentation and then used immobilized acetic acid bacteria for vinegar fermentation. [Result] The general quality of apple vinegar brewed by MMCT was superior to the others. Its total acidity reached to 3.845 g/100 ml, unvolatile acidity was about 0.600 g/100 ml, amino-nitrogen was higher than 0.510 g/100 ml, and the composing of flavor compounds was almost similar to that of SSF brewed apple vinegar. [Conclusion] The MMCT method was proven to be the optimum one for high quality apple vinegar brewing and might be widely used in the future.[目的]比较不同酿造方法所得苹果醋的品种,筛选出最佳的苹果醋酿造方法。[方法]对三种传统酿造方法和一种本课题组前期新建酿造方法所得苹果醋的品质进行了分析。三种传统酿造方法分别为固态发酵法(SSF)、液态发酵法(LSF)和固定化发酵法(IMF);新建酿造方法为多菌种共固定法(MMCT),即采用酿酒酵母、产香酵母以及乳酸菌的共固定颗粒(比例为6:3:1)进行酒精发酵,再利用固定化醋酸菌进行醋酸发酵。[结果]采用多菌种共固定技术酿造所得苹果醋的总体品质最好,其总酸含量为3.845g/100ml,不挥发性酸含量为0.600g/100ml,氨基态氮含量高于0.510g/100ml,香气成分构成与固态发酵法所得苹果醋最为相似。[结论]多菌种共固定技术最适合用于高品质苹果醋的酿造,该技术具有较好的应用前景。
