2.4. Rheological analysis
Rheological characterization of the emulsions was carried out using a Haake Mars II (Thermo Electron GmbH, Germany) rheome- ter that is equipped with a circulating water bath (DC5, Haake) and a Peltier (TC 81, Haake) temperature control unit for maintaining the desired temperatures during analysis. Measurements were per- formed at 10 and 25 °C, using cone and plate geometry with a cone diameter of 60 mm and a cone angle of 2°. Data collection, treat- ment, and regression were performed using RheoWin 3 software (Haake). After loading the sample into the rheometer, the emulsion remained unperturbed for 5 min before the following tests were performed: (1) flow curve (c_ = 0.1–100 s
