吸附剂对啤酒中嘌呤类物质吸附的研究

Research on the Absorption of Purine Compounds in Beer by Absorbents

建立了几种吸附剂对啤酒中嘌呤类物质吸附的方法。研究这几种吸附剂对嘌呤类物质的吸附率,研究活性炭和壳聚糖的颗粒度、吸附时间、吸附温度、添加量、溶液pH值对吸附率的影响,在优化的吸附条件下对啤酒酒样进行吸附,活性炭和壳聚糖对啤酒中的嘌呤类物质的总吸附率分别为68.2%和42.8%。

The absorption methods ofpurine compounds in beer by several kinds of absorbents had been developed. The effects of different kinds of absorbents on the absorption rate ofpurine compounds were studied. Besides, the effects of the grain size of active carbon and chitosan, the absorption time, the absorption temperature, the addition levels, and the solution pH values on the absorption rate of purine compounds were investigated. The beer samples absorption test results showed that the total absorption rates of purine compotmds in beer by active carbon and by chitosan were 68.2 % and 42.8 % respectively under the optimized absorption conditions.
