Abstract:
In this study, the viscosity of sunflower oil obtained by protease (alkalase), hemicellulase and ultrasonic extraction method, which is used to obtain oil from sunflower seeds, was investigated. The highest viscosity value in crude sunflower oil with protease enzyme was measured as 44.2 Pa.S (25° C). When the hemicellulase enzyme was used at 2.0% concentration in crude sunflower oil, the viscosity value was 43.9 Pa.S (25° C). In the ultrasonic extraction method, the viscosity values of crude sunflower oils for 10 min, 20 min and 30 min were measured as 38.4 Pa.S (25° C), 38.9 Pa.S (25° C), and 33.2 Pa.S (25° C), respectively.
