Rheological Properties of Sübye, Traditional Beverage

Sübye is a traditional cold beverage and consists of melon seeds, sugar and water. Sübye production is important in economic and environmental point of view since melon seeds, wastes of food production, are used as a raw material. In this study, rheological properties of Sübye were determined by fitting shear stress–shear rate data to some rheological models. Herschel-Bulkley model was the best model that fitted the experimental data (R2=0.996, X2=0.0245, RMSE=0.0008). Also Sübye showed time-dependent rheopectic characteristics at low and high shear rates whereas thixotropic characteristics existed at medium shear rates.
