The effects of additives (sucrose, glucose and sodium chloride) on textural properties of native and annealed corn starch gels were measured using DSC (Differential Scanning Calorimetry), XRD (X-ray diffraction), SEM (Scanning Electron Microscopy) and TA (Texture Analyzer).Annealing temperature, additive concentration and pH affected the corn starch gels. Firmness, consistency, cohesiveness and viscosity values ranged from 20.55 to 43.70 g, 213.67 to 412.00 g/sec, -25.81 to -15.22 g and -104.21 to -6.73 g/sec, respectively. The eigenvalue of the texture characteristics of annealed corn starch decreased without additives, and increased with additives.Annealing at 55 °C had more effect than did annealing at 45 °C.
