CN201310443498.4的优先权。 本申请引用上述中国专利申请的全文。 技术领域
本发明公开了一种葡聚糖饮料及其制备方法。 背景技术
多糖 (polysaccharide ) 是一种由单糖以糖苷键键合而成大分子聚合物, 研究表明,多糖具有免疫调节、抗病毒、抗癌、降血糖、降血压等益生功能。 自然界中的多糖主要分布于微生物、 高等植物、 动物、 地衣以及藻类中, 其 中, 微生物来源的多糖尤指其胞外多糖, 为某些特定微生物 (如乳酸菌、 土 壤杆菌、 根瘤菌等) 在生长代谢过程中分泌到细胞壁外的一类糖类化合物, 其中, 依附于微生物细胞壁外的多糖被称为荚膜多糖, 而粘液多糖则以渗透 于生长环境中的形式存在。
