一般說明
葡聚糖（分子量270,000）属于中性多糖家族，是糖加工和其他食品生产行业中的污染物。它们由通过α-（1-6）糖苷键连接的不同长度的D-葡萄糖单元链组成。它们是细菌胞外多糖，据报道是由有益的乳酸菌（如肠膜明串珠菌和短乳杆菌）以蔗糖合成的。它们可掺入焙烤制品中以改善面包屑质地、柔软度和面包体积，可作为糖果、风味提取物，糖衣组合物、饮料（包括软饮料、牛奶等）中的稳定剂和添加剂。
應用
分析标准品也可用于以下用途：
- 基于高效粒径排阻色谱法（HPSEC）测定葡聚糖（通过从菠萝发酵产物分离的柠檬酸白细胞 B-2 合成）的分子量
- 使用水溶性凝胶柱通过高效液相色谱法测定从四种木耳中提取的多糖的分子量
- 通过凝胶渗透色谱法（GPC）鉴定使用阴离子交换色谱法从苦参叶分离的水溶性多糖的分子量
- 通过凝胶渗透色谱（GPC）法测定两株肠系膜白菌所产生的葡聚糖的分子量
- 通过高效粒径排阻色谱法（HPSEC）估测薄皮苹果中水溶性多糖的分子量
