摘　　要：随着纯生啤酒等高端啤酒产量的增加,啤酒生产对影响黏度和过滤速度的大分子物质含量的要求越来越高。阿拉伯木聚糖是组成大麦胚乳细胞壁的主要非淀粉多糖之一,能够形成高黏度的溶液,影响麦汁和啤酒的黏度和过滤速度。文中从结构、含量的检测、降解及研究展望等方面分析了大麦麦芽阿拉伯木聚糖的研究现状,指出了存在的问题。建立准确的高分子量阿拉伯木聚糖检测方法,研究不同分子量的阿拉伯木聚糖含量对黏度和过滤速度的影响,研究大麦麦芽的内源木聚糖酶抑制剂对阿拉伯木聚糖降解的影响以及高效降解阿拉伯木聚糖的酶制剂配方是今后的发展方向。With the increase of production of the premium beer such as draft beer, there are more and more de- mands for controlling the content of substances which affects the viscosity and filtration rate during beer production. Arabinoxylan is one of the major non-starch polysaccharides of the endosperm cell wall in barley, which could form highly viscous solution and have a negative effect on the viscosity and filtration rate of wort and beer. In this paper, the structure, determination and degradation of arabinoxylan, the existing problems and further research direction were discussed. Establishment of an accurate determination method for high molecular weight arabinoxylan, the influence of different molecular weight of arabinoxylan on the viscosity and filtration rate, the effect of malt-derived endoxylanase inhibitor on arabinoxylan degradation, and the enzyme preparation for highly efficient degradation of arabinoxylan were research directions in future.
