一般說明

葡聚糖(分子量80,000)属于中性多糖类家族, 它是糖加工和其他食品生产行业中的污染物。 这些糖由不同长度的α-(1-6) 糖苷键连接的D-葡萄糖单元所组成。它们以细菌胞外多糖的形式存在于细菌中,据报道是由蔗糖通过有益乳酸菌(如肠膜明串珠菌短乳杆菌)合成。它们可加入焙烤制品中以改善面包心质构、柔软度和面包体积,另外还可作为稳定剂和添加剂用于糖果、风味提取物、结冰组合物、饮料(包括软饮料、牛奶等)。

應用

葡聚糖已被用作聚合物标准品,用于通过荧光寿命成像显微(FLIM)和CoroNaGreen 染料定量测定胞内钠[Na+] 。它还可与伴刀豆球蛋白A一起用于渗透性葡萄糖传感器中的伴刀豆球蛋白A亲和检测,对商业化纳米微孔膜进行表征。

包裝
