Biophysical properties of Opuntia ficus-indica mucilage
The purified mucilage from Opuntia ficus-indica is a high MW polysaccharide which behaves as a polyelectrolyte. Viscosity of its solution is dependent on the Ca2+ ion concentration and on pH, being greatest at alkaline pH. The sedimentation coefficient was dependent on concentration. The molecule had an estimated axial ratio... |
