摘　　要：木聚糖酶(Xylanase,EC.3.2.1.8)是指一类能够将半纤维素木聚糖降解成低聚木糖和少量木糖、阿拉伯糖的一组酶系的总称。目前,木聚糖酶在制浆造纸业中的应用最为广泛,尤其是在纸浆生物漂白方面显示出了巨大的应用价值,引起了同行各界的关注。同时,近几年,有研究者开始将木聚糖酶的应用研究转移到了食品加工生产上,以期木聚糖酶能够在食品工业上形成规模化应用,进而加速促进我国木聚糖酶产业化的成熟。文章主要对木聚糖酶的特性,以及其在面制品制作、功能性低聚木糖制备等食品工业中的研究应用进行了综述,分析了木聚糖酶在工业化生产应用过程中面临的问题,并对其应用前景进行了展望。Xylanase （E. C. 3. 2. 1. 8） is a kind of enzymes which can breakdown the linear polysaccharide β- 1,4-xylan into xylose, xylobiose, or xylotriose. At present, xylanase is the most widely used in the pulp and paper industry, especially in the pulp bio-bleaching. The enzyme has very extensive application value and great exploitation foreground, thus, more and more researchers have begun to pay attention to this aspect. At the same time, some of them have started to study the application of xylanase in food processing in recent years, in order to develop large- scale applications of xylanase in the food industry and also to speed up the process of xylanase industrialization in China. This article mainly introduces the nature of xylanase, along with the application in food industry such as flour products production, xylo-oligosaccharide production and so on. And also analyze the problem in the application of xylanase the industrial production, as well as the perspective of its application.
