Title: Process for the purification and concentration of solutions derived from marine algae
IPC: A23L29/256
Filed: 1973-07-17
Abstract: 1432166 Ultrafiltration of marine algae polysaccharides UNIROYAL Ltd 17 July 1973 [16 Aug 1972] 34013/73 Heading C3U A method of purifying and concentrating an aqueous solution of a polysaccharide derived from marine algae comprises subjecting said solution to ultrafiltration using a semi-permeable ultra-filtration membrane having an apparent pore diameter of 20-400 Angstrom units and thereby causing water and low molecular weight species to pass through said membrane and the polysaccharide to be retained by said membrane. Physical conditions of ultrafiltration pressures, temperatures and pH values are specified. The polysaccharide may be a calcium derivative or an ester, e.g. a propylene glycol ester and the calcium derivative may, prior to ultrafiltration, be subjected to ion exchange to replace the calcium ions of the polysaccharide with potassium, sodium or ammonium ions, e.g. by treatment of the polysaccharide solution with Na, K, or NH 4  carbonate and separating the precipitated calcium carbonate thereby formed. Specified polysaccharide sources exemplified are Chondrus crispus (carrageenan), Furcellaria fastigrata (calcium furcellaran), Phyllophora membranifolia (calcium phyllophoran), Ascophyllum nodasum (ion exchanged to give sodium alginate).
