This study investigates the effect of the ultrafiltration process on physicochemical, rheological, microstructure and thermal properties of syrups from male and female date palm sap. All the studied syrups switched from pseudoplastic rheological behaviour (n=0.783) to Newtonian behaviour (n∼1) from 10 to 50°C respectively and present similar thermal profiles. Results revealed that the ultrafiltration...
A knowledge of rheological properties is of importance in processing, handling, process design, product development and quality control. This study investigates the effect of commercial hydrolytic enzymes (pectinase and cellulase) on rheological properties and glass temperature transition of date syrup. Date syrups obtained by enzymatic extraction exhibited a quasi Newtonian behaviour.The enzyme-treated...
