【摘要】 低聚木糖是一种以天然植物纤维为原料,采用先进生物技术精制而得的功能性低聚糖类,具有增殖益生菌的功能。这种功能性食品添加剂的出现,不仅将促进我国低聚糖工业向一个新的方向发展,而且还可以处理农林废料,变废为宝,保护环境。我国稻壳资源丰富,价格低,使得低聚木糖生产成本低,开发途径具有很强的市场竞争能力和十分重大的经济效益和社会效益。目前国内对以玉米芯、甘蔗渣、稻草等纤维素物质为原料制备低聚糖进行了探索,而以稻壳为原料制低聚糖的报道很少,资源优势尚未转化为经济优势。本文对低聚木糖的物化性质和生理功能做了介绍,对从稻壳中提取低聚木糖的研究进展进行了综述,并为合理利用稻壳提取低聚木糖进行了展望。更多还原

【Abstract】 Xylo-oligosaccharide is a kind of oligosaccharide,taken by Biotechnology methods from natural vegetable fibre materials.Xylo-oligosaccharide could enhance the proliferation of Bifido-bacterium.The emergence of these functional food additives will not only promote China’s oligosaccharide industry to a new direction,but also could dispose agriculture and forestry offal,solving the problem of environmental pollution.These account for 30 percent of world production over,ranking first in the world.The resource of rice hull is rich in china,and the price is low as well.So in the product of Xylo-oligosaccharide,the economic returns and the competitive of products was well.It had good economic and social benefit.Now,some research on the extraction of Xylo-oligosaccharide from corncob,bagasse,and straw had been done.However,there are few reports about the extraction Xylo-oligosaccharide from rice hull.And the resources superiority could not convert to economic benefit.In this paper,the physiological function and properties of xylo-oligosaccharide were introduced.We summarize the research progress on extraction of xylo-oligosaccharide from rice hull,and propose the rational utilization on used rice hull.更多还原
