Cello-oligosaccharide has drawn an increasing attention as the nutritional ingredients of dietary supplements, whose quality is affected by the concentration of monosaccharide. In the present study, an effective process was developed for the simultaneous production of cello-oligosaccharide and glucose mono-decanoate from lignocellulose by enzymatic esterification. During the process, the excessive glucose in cello-oligosaccharide was converted into glucose mono-decanoate, which is a well-known biodegradable nonionic surfactant. The filter paper was initially used as the model to investigate the feasibility of the process, in which the purity of resultant cello-oligosaccharide was increased from 33.3% to 74.3%, simultaneously producing glucose mono-decanoate with a purity of 92.3%. Further verification of 3 kinds of lignocelluloses (switchgrass, cornstalk, and reed) also indicated a good performance of the process. The present process provided an effective strategy to increase the purity of resultant cello-oligosaccharide with the simultaneous production of high value–added products of sugar monoester.

纤维寡糖作为膳食补充剂的营养成分已受到越来越多的关注，其质量受单糖浓度影响。在本研究中，开发了一种通过酶促酯化从木质纤维素同时生产纤维寡糖和单癸酸葡萄糖的有效方法。在此过程中，纤维寡糖中过量的葡萄糖被转化为单癸酸葡萄糖，这是众所周知的可生物降解的非离子表面活性剂。最初将滤纸用作模型以研究该方法的可行性，其中所得纤维寡糖的纯度从33.3％提高至74.3％，同时生产纯度为92.3％的单癸酸葡萄糖。进一步验证3种木质纤维素（柳枝,、玉米秸秆和芦苇）也表明该过程表现良好。本工艺提供了一种有效的策略，可通过同时生产高附加值的糖单酯产品来提高所得纤维寡糖的纯度。
