摘要: Abstract The dynamic rheology and confocal laser scanning microscopy (CLSM) of gellan at low concentrations (0.005–0.05 wt%) in the presence 10 mM CaCl 2 were investigated 25 °C. DSC thermograms showed a conformational transition from coil to rigid helix approximately 41 Microscopy observations demonstrated that these concentrations, level counter ions induced formation network, compactness which depended on concentration. reinforcement network structures by increase concentration resulted more elastic gels well evidenced through systems.
