摘要: The rheological characteristics of polysaccharides which were extracted and separated from Ulva fasciata (UFP) investigated in aqueous solutions under conditions concentration, temperature, solution pH salt concentrations. It was described by the power-law model with a consistency index (k) flow behavior (n). rheology results showed UFP exhibited as shear-thickening fluid possible mechanism proposed to explain this phenomenon that might be collapse necklace-type structures. evaluated determining chemical analysis zeta potential. findings indicated may consist partially ulvan, accordance ulvan structure. Additionally, rod-climbing effect cold-set gelation observed semidilute solution. Therefore, gelling properties unique work could valuable for exploration U. new source water-soluble polysaccharides.
