Rheological properties of natural low-methoxyl sunflower pectin have been investigated. Sugar composition and molecular parameters of SFHP were characterized. The M w and M n of SFHP is 605.6 kDa, 111.0 kDa, respectively, thereby giving a moderate polydispersion index of 5.50. Huggins plot indicated a stiff rod-like conformation of SFHP in dilute solution. Dilute SFHP solution (<1...
Hydrodynamic behavior and gelling properties of sunflower head pectin (SFHP) regulated by sodium salts were investigated. Huggins plots of SFHP solutions at different pH in the presence of NaCl and Na 2 SO 4 (0.01, 0.05 and 0.10 M) were depicted by capillary viscometric analysis. The gelling process of SFHP solution (1%, w/v) during cooling from 75 °C to 10 °C induced by NaCl and Na...
