阿拉伯木聚糖和阿拉伯低聚木糖的益生功能研究进展

Research Progress on Prebiotic Effects of Arabinoxylan and Arabinoxylan Oligosaccharides

畜禽肠道健康的调控已成为当今畜牧业中的重点关注问题。阿拉伯木聚糖(AX)和阿拉伯低聚木糖(AXOS)作为新型的益生元,其对双歧杆菌等益生菌的增殖效果优于低聚果糖等益生元。此外,与低聚果糖等益生元相比,AX和AXOS能够进入肠道后段进行发酵,生成非支链的短链脂肪酸,并抑制蛋白质的发酵,减少有毒物质(苯酚、氨等)的生成,从而有效地调节后肠段(结肠和盲肠)的健康。不同结构的AX和AXOS具有不同的益生功能,且AX和AXOS间存在协同增效的益生作用。本文综述了近年来关于AX和AXOS的益生功能的研究进展,为其在畜牧业中的应用提供一定的理论依据和指导。

The research on regulation of gut health of livestock has been focused on in recent years.As novel prebiotics,arabinoxylan（AX） and arabinoxylan oligosaccharides（AXOS） show better proliferation effects on Bifidobacterium than fructooligosaccharides and other oligosaccharides.Besides,AX and AXOS can efficiently regulate the health of hindgut（colon and cecum） via fermentation in the hindgut to produce non-branched short chain fatty acids and inhibit protein fermentation to lower the production of toxic substance（phenol,ammonia and so on）.Structural differently AX and AXOS have different fermentation properties and can produce synergistic effect.This paper reviewed the research progress of prebiotic effects of AX and AXOS in recent years,which provides a theoretical basis and instruction for their application in livestock industry.
