The effect of frozen storage on the solubility, viscosity, rheological and electrophoretic behaviour of myofibrils was studied. The solubility, viscosity, swelling and thixotropic behaviour of myofibrils showed a period in which it was constant or changed slowly, and then began to decrease. The results obtained by polyacrylamide gel electrophoresis indicated that during storage the formation of aggregates occurred in addition to alteration in the actin-myosin interaction. These results were correlated with those obtained from measurements of viscosity, rheological behaviour and swelling of myofibrils in solution.
