“…Pressure-gelatinized barley starch seemed to be less sensitive and potato starch more sensitive to retrogradation (as measured by DSC during eight days' storage at 5°C) than the corresponding heat-gelatinized starches. Douzals et al (1996) subjected wheat starch suspensions in water (15-40% dry solids) to high pressure (100-600 MPa, room temperature, time not indicated) in a manual screw piston pump designed to measure the isothermal macroscopic compressibility (-Ll VIVo x LlP). As the pressure increased to 600 MPa, the compressibility of the starch suspension (33% dry solids) progressively decreased, as expected, but became higher than that of pure water above 300 MPa.…”
