文摘

Autohydrolysis was an efficient technique to recover polysaccharides from SCG. Process conditions were optimized to obtain high yield of antioxidant polysaccharides. Galactomannans and arabinogalactans were the main polysaccharides obtained. SCG polysaccharides presented thermostability in a large range of temperature
