摘　　要：初步探讨了用蒸汽爆破玉米秸秆技术制备木低聚糖和可溶性木聚糖的工艺条件。结果发现，采用１．６ ＭＰａ 和２．０ ＭＰａ 的蒸汽压，维压５ ｍ ｉｎ，可以使戊聚糖较好地溶出，戊聚糖回收率达４０．０％ ～５９．０％ 。其中，低聚糖得率达３６．０％ ～５９．０％ 。在２．０ ＭＰａ的压力条件下，加水有利于戊聚糖的溶出，缓解聚糖的降解。Xylo oligosaccharide production from corn stalk with steam explosion was investigated. The results indicated that pentosan can be dissolved from corn stalk with 1.6 MPa or 2.0 MPa steam pressure easily. The yields of pentosan and oligosaccharides reached 40.0%～59.0% and 36.0%～59.0%,respectively. Under 2.0 MPa pressure, the addition of water was beneficial to the dissolution of pentosan and reduction of polysaccharide decomposition
