Research on Properties of High-Acyl Gellan Gum

The rheological and gelling strength of high-acyl gellan gum at different concentration,temperature,pH and different calcium were carefully investigated in this manuscript.studied.High-acyl gellan gum was to investigate the gelling properties and gelling mechanism.The results showed that the different concentration,temperature,pH and calcium can affect the viscosity and gelatin strength of high-acyl gellan gum.Hydrogen bond,electrostatic force and hydrophobic interaction are the vital factors to the formation of high-acyl gellan gum,among them,it was believed that hydrophobic interaction play most importance.
