摘　　要：为解决工业生产中海红果酒有机酸含量较高的难题,试验研究了离子交换树脂对低度海红果酒的降酸效果及其影响因素。采用6种离子交换树脂对海红果酒进行吸附降酸,通过测定吸附前后海红果酒的主要理化指标,筛选出降酸效果最佳的树脂。研究了最佳的离子交换树脂的静态吸附和动态吸附试验。结果表明,A451弱碱性阴离子交换树脂是低度海红果酒的最适降酸树脂;A451离子交换树脂与酒样以1∶20的比例静态吸附300 min后,树脂达到吸附平衡,此时树脂对总酸的表观交换吸附量为0.128 g/g;温度对海红果酒离子交换法降酸影响不明显;流速对A451离子交换树脂吸附降酸有显著的影响,较低的流速可以获得较大的处理量,A451离子交换树脂的最佳作用流速为3 BV/h。In order to reduce the organic acid content of Malus micromalus Makino wine for the sake of its industrial production, the effect of ion exchange resin on deaeidification of low-alcohol Malus micromalus Makino wine and its related influence factors were evaluated. 6 kinds of ion exchange resins were applied to treat low-alcohol Malus micromalus Makino wine, the most suitable resin was selected according to the main physical and chemical indicators before and after treatment. Static and dynamic adsorption experiments of the selected resin were also investigated. Results showed that the weakly basic anion exchange resin A451 was the optimal resin for the Malus micromalus Makino Wine. In addition, A451 reached adsorption equilibrium after 300 rain of static adsorption when the ratio of resin to wine was 1： 20. And apparent exchange adsorption capacity of total acid was 0. 128 g/g. Results also showed that the effect of temperature on the deacidification of Malus micromalus Makino wine with A451 was not evident. In dynamic adsorption experiment, the deacidification with A451 was significantly affected by flow rate. Lower flow rate could obtain higher processing volume. The optimal flow rate of A451 for low-alcohol Malus micromalus Makino wine was 3 BV/h.
