Abstract: The effect of temperature and molecular weight, on the conformational properties of agar aqueous solutions is reported. Equations of the viscosity agar solutions for different concentrations, and molecular weight, are given. The thermoreversible sol gel transition in agar gel is studied by small deformation oscillatory measurements of storage G′ and loss modulus G″. The gelation and melting temperatures are given for different concentrations and molecular weights. Gelation enthalpies are calculated by the Ferry–Eldrige model, effect of nature and molecular weight of agar are discussed.
