N2 - Based on its potential bioactivities and sustainable source, polysaccharide (glucuronoxylomannan) from fruit bodies of Tremella fuciformis (TFP) aroused attention in food, pharmaceutical and cosmetic industry. The present study aimed at revealing its chain conformational and physicochemical properties. By using HPSEC-MALLS-Visc-RI measurement, worm-like cylinder model calculation and AFM observation, we manifested that TFP existed as flexible chains in 0.15 M NaCl (pH 7.4) solution, with the persistence length of 9.20 nm and chain diameter of 0.97 nm. Meanwhile, TFP solution exhibited shear-thinning behavior with C* at 5.3 mg mL−1, owning the feature of entangled polysaccharide. TFP solution changed from liquid-like to solid-like behavior as frequency increases, and the crossover points shifted to lower frequencies with concentration increasing. Besides, the strong moisture retention ability of TFP was evaluated. These characteristics indicated that TFP could be utilized to design microstructure system and applied as stabilizer or moisture holding ingredient in food, pharmaceutical and cosmetic system.
