低聚木糖xylo-oligosaccharide

低聚木糖，又称木寡糖，英文缩写 XOS，是由 2–7 个木糖单元以 β-1,4 糖苷键连接构成的低聚糖混合物。本品以玉米芯为原料，经酶解、分离、精制、干燥制得，外观为白色或微黄色粉末，有相应甜度，具备较好的耐热、耐酸特性。

Xylo-oligosaccharide (XOS), also known as xylooligosaccharides, is a mixture of oligosaccharides consisting of 2–7 xylose units linked by β-1,4 glycosidic bonds. It is produced from corncob via enzymatic hydrolysis, separation, purification and drying. The product appears as white or pale yellow powder with sweetness, featuring good heat resistance and acid tolerance.
