摘　　要：该实验在优化膜分离预处理工艺参数的基础上,考察了采用膜分离-树脂吸附的物理方法来调整黄酒酸度指标的工艺过程,并对降酸黄酒的风味品质进行了比较分析。结果表明,在料液温度25℃,运行压力1.0 MPa,截留分子质量为200、1000、2000 Da的不同膜预处理条件下,D354树脂对高酸黄酒的降酸率分别达到47.0%、53.8%、68.1%。降酸黄酒样品中共检测到32种挥发性风味物质,200、1000 Da膜预处理组获得的降酸黄酒样品中挥发性风味物质总含量分别达到1975.89、1919.80 mg/L,均显著高于未过膜处理组(1727.04 mg/L)。层次聚类分析表明,1000 Da和2000 Da组之间的风味相似度更高,正交偏最小二乘判别分析表明11种化合物对降酸黄酒的风味差异贡献较高。选用1000 Da膜预处理,结合10%填充比的D354树脂处理50 L高酸黄酒,总酸下降率达57.7%,氨基酸态氮保留率达98.8%,挥发性风味物质的保留率达80.0%。该研究为高酸黄酒的物理降酸提供了新的视角和应用场景。In this study,the parameters of membrane separation pretreatment were optimized,and the feasibility of reducing the acidity of Huangjiu by the method of membrane separation-resin adsorption was investigated.Then,the flavor of Huangjiu after reducing acidity was evaluated.The results showed that under the Huangjiu temperature of 25℃and the operating pressure of 1.0 MPa,the acid-reducing rate of high-acid Huangjiu after D354 resin adsorption reached 47.0%,53.8%,and 68.1%respectively,after being pretreated with different membranes with a molecular weight of 200 Da,1000 Da,and 2000 Da.A total of 32 volatile substances were detected in the Huangjiu samples after reducing acidity.The content of volatile substances in the 200 Da(1975.89 mg/L)and 1000 Da(1919.80 mg/L)membrane pretreatment groups were significantly higher than group without membrane pretreatment(1727.04 mg/L).In addition,the hierarchical cluster analysis showed that higher flavor similarity between 1000 Da and 2000 Da groups.Eleven volatile substances with significant differences between different deacidification Huangjiu groups were obtained based on the results of OPLS-DA combined the variable importance in projection.Using 1000 Da membrane pretreatment combined with 10%filling ratio D354 resin adsorption to reduce the acidity of 50 L high-acid Huangjiu.The results showed that the total deacidification rate reached 57.7%and the retention rates of amino acid nitrogen and volatile components were 98.8%and 80%,respectively.In summary,this study provides a new perspective and application scenario for the physical deacidification of high-acid Huangjiu.
