摘要
低聚木糖(xylo-oligosaccharide,XOS)又称木寡糖或寡聚糖,由2~7个木糖以β-1,4糖苷键首尾相连而成,是一类具有益生元活性的短链聚合物。XOS具有热值低、稳定性强等特点,在动物肠道内不易被消化酶识别和分解,但可被肠道内的有益菌分解利用。XOS来源广泛,无毒副作用,能够提高肠道内双歧杆菌活性。作为一种绿色功能性低聚糖,XOS在医药、农业、饲料、食品等方面均有广泛的应用。XOS具有抑菌、抗炎、调节血糖、抗氧化等生理功能,在动物生产中具有极大的应用潜力。文章结合国内外关于XOS的研究进展,对XOS制备方法进行了归纳总结,并结合其生理功能对其在动物生产上的实际应用进行综述,为XOS在动物生产中的合理利用提供参考。
Xylo-oligosaccharide(XOS),also known as xylo-oligosaccharides or oligosaccharides,is a class of short chain polymers with prebiotic activity,consisting of 2~7 xyloses connected byβ-1,4 glucoside bonds.XOS has the characteristics of low calorific value and strong stability,which makes XOS difficult to be recognized and decomposed by digestive enzymes in the animal intestine,but it can be decomposed and utilized by beneficial bacteria in the intestine.XOS comes from a wide range of sources,has no toxic side effects,and can improve the activity of Bifidobacteriumin the intestine.As a green functional oligosaccharide,XOS is widely used in medicine,agriculture,feed,food,and so on.XOS has the physiological functions of antibacterial,anti-inflammatory,regulating blood sugar,antioxidant,and so on,which has great application potential in animal production.Based on the research progress of XOS at home and abroad,the preparation methods of XOS were summarized,and the practical application of XOS in animal production was reviewed in combination with its physiological functions,so as to provide a reference for the rational utilization of XOS in animal production.
