Binding properties are important for meat products and are substantially derived from the heat-induced gelation of myosin. We have shown that myosin is solubilized in a low ionic strength solution containing L-histidine. To clarify its processing characteristics, we investigated properties and structures of heat-induced gels of myosin solubilized in a low ionic strength solution containing t-histidine. Myosin in a low ionic strength solution formed transparent gels at 40-50 degrees C, while myosin in a high ionic strength solution formed opaque gels at 60-70 degrees C. The gel of myosin in a low ionic strength solution with t-histidine showed a fine network consisting of thin strands and its viscosity was lower than that of myosin in a high ionic strength solution at 40-50 degrees C. The rheological properties of heat-induced gels of myosin at low ionic strength are different from those at high ionic strength. This difference might be caused by structural changes in the rod region of myosin in a low ionic strength solution containing t-histidine. (C) 2011 Elsevier Ltd. All rights reserved.
