产品应用
- 生物培养，鞣革，染色，糖尿病食品。木糖与日常食用的葡萄糖及果糖等不同，其不能为人体提供热量，对人体肠道内的双岐杆菌有较高的增殖作用，能改善人体微生态环境，提高机体免疫能力，主要用于制取木糖醇，在食品加工、制药工业也有广泛应用。

其他信息
- 木糖为白色结晶或结晶性粉末，味甜，甜度相当于蔗糖的0.7；具旋光性；易溶于水，20°C时溶解度117g，在同等温度条件下，其饱和溶液的粘度比木糖醇、葡萄糖均小。，能还原温热的斐林氏溶液。溶于水、吡啶和热乙醇，微溶于冷乙醇。木糖(xylose)属于五碳糖，以缩聚状态广泛存在于自然界植物的半纤维素中，即以大分子的木聚糖的形式含在植物体内。如存在于木屑、稻草、玉米芯等。
