Abstract The dynamic modulus began to decrease rapidly and loss tanδ showed maxima at the temperature range from 40 °C to 65 °C in polysaccharide gels extracted fromAhnfeltia plicata. An exothermic peak appeared at about 30 °C in heating DSC thermograms for these gels. Endothermic DSC peaks accompanying gel-sol transition appeared at the temperature range from 60 °C to 80 °C. The effects of alkali pretreatment and of maturation on the rheological and thermal properties of these gels were examined.
