Flow behavior of the SP/CGJ blends were expressed by Powerlaw model, however SP/honey and SP/sugar syrup blends were fitted to theBingham Plastic model. The relationship of the consistency index "K"and SP concentration was described by exponential and power functions. Risingin temperature lead to a decrease in the consistency index of SP blends.Increasing in SP concentration resulted in an increase in consistency index ofsamples. Sensorial analysis was evaluated to research the effect of SP concentrationand type of sugar sources on sensorial properties. Spreadibility andmouth-coating properties of blends enhanced with the increase in SPconcentration. Moreover rheological properties highly correlated with sensorialproperties of samples.
