研究了利用香菇栽培废弃料生产低聚木糖的有效性。WM含有丰富的营养成分（蛋白质等）。其在水热条件下诱导与还原糖的美拉德反应。为了提高XO的产率，研究了合适的预处理方法，包括洗涤和研磨，并采用间歇式和连续流动式反应器进行了水热处理。用60°C的热水进行的洗涤预处理有效地从WM中去除营养物，并且其导致防止水热处理时的褐色变色。在实验数据的基础上，设计了由预处理、水热处理和纯化步骤组成的工业化生产工艺。在设计的工艺过程中，从30 kg湿的WM生产2.3 kg干的纯化XO（15%产率，以干基重计）。木糖的理论产率达到48%，以木聚糖重量计。
The effective xylooligosaccharides (XOs) production from the waste medium after mushroom cultivation (WM) was investigated. The WM contains rich nutrients (protein, etc.) which induce Maillard reaction with reducing sugars under hydrothermal conditions. To improve the productivity of XOs, the suitable pretreatment combined with washing and grinding was investigated, and subsequently hydrothermal treatment was demonstrated with batch type and continuous flow type reactor. The washing pretreatment with hot water of 60°C was effective to remove nutrients from the WM, and it led to prevent brownish discoloration on the hydrothermal treatment. On the basis of experimental data, industrial XOs production processes consisting of the pretreatment, hydrothermal treatment and purification step was designed. During the designed process, 2.3kg-dry of the purified XOs was produced from 30kg-wet of the WM (15% yield as dry basis weight). Theoretical yield of XOs attained to 48% as xylan weight in the WM.
