seed dreg polysaccharides (LBSDPs) were continuously extracted with four different solvents [hot buffer (HBSS), chelating agent (CHSS), dilute alkaline (DASS), and concentrated alkaline (CASS)]. The present study characterized the physicochemical and anti-oxidant based functional properties of different LBSDPs. The monosaccharide analysis revealed xylose (64.63%, 70.00%, 44.71%, and 66.67%) as the main sugar with the molecular weights of 5985, 7062, 5962, and 8762 Da in HBSS, CHSS, DASS, and CASS, respectively. Among the four polysaccharides, CASS had the strongest DPPH radical scavenging ability and reducing power; while, CHSS had the strongest ferrous ions chelating ability and HBSS showed the strongest OH radical scavenging ability. In terms of functional properties, HBSS and CASS had better solubility and oil holding capacity, while, CASS and CHSS had higher foam capacity and foam stability. Altogether, the polysaccharides extracted from seed dreg exhibit a potential application prospect in functional food and cosmetics industries.
用四种不同溶剂[热缓冲液（HBSS）、螯合剂（CHSS）、稀碱（DASS）和浓碱（CASS）]连续提取籽粕多糖（LBSDPs）。本研究对不同LBSDPs的物理化学性质和基于抗氧化的功能特性进行了表征。单糖分析表明，木糖（分别为64.63%、70.00%、44.71%和66.67%）是主要糖类，其在HBSS、CHSS、DASS和CASS中的分子量分别为5985、7062、5962和8762 Da。在这四种多糖中，CASS具有最强的DPPH自由基清除能力和还原能力；而CHSS具有最强的亚铁离子螯合能力，HBSS表现出最强的羟基自由基清除能力。在功能特性方面，HBSS和CASS具有较好的溶解性和持油能力，而CASS和CHSS具有较高的泡沫容量和泡沫稳定性。总之，从籽粕中提取的多糖在功能食品和化妆品行业具有潜在的应用前景。
