- Bound Water at Sol Gel Transition in Bi

抄録
The relationship between sol-gel transition and bound water in bilayer aqueous systems of egg lecithin (EL) was studied by means of rheological, NMR and dielectric measurements. The viscosity and rigidity of the systems increase very sharply at the critical gel concentration c*, and the reciprocal value of the spin-lattice relaxation time of the water proton, T1-1, which is proportional to the correlation time of molecular motion, also increases sharply at c*. This means that the bound water is strongly related to the sol-gel transition of the bilayer aqueous systems of EL. It was confirmed by the dielectric measurements that there were three types of bound water whose characteristic dielectric relaxation times are 2.0×10-8s, 2.3×10-9s and 2.5×10-10s.
