摘要：

The effect of a magnetic field (0.3 T) on the sol-gel transition of methylcellulose (MC) in water was studied by means of rheology. It has been found that (1) the magnetic field causes the sol-gel transition temperature of MC to shift to the lower temperature by about 3 degrees C, showing a salt-out like effect, (2) the magnetic field shows a weaker effect on the sol-gel transition when NaCl is present, and (3) the gel strength is not strongly affected by the magnetic field but a slight increase in the gel strength is observed. The possible mechanisms for these interesting phenomena are proposed and discussed. (c) 2007 Elsevier Ltd. All rights reserved.
