FREMGANGSMAATE TIL FREMSTILLING AV RENSEDE OG KONSENTRERTE POLYSAKKARIDOPPLOESNINGER FRA MARINE ALGER

摘要

Method of purifying and concentrating aqueous solutions derived from marine algae by subjecting such solutions to ultrafiltration whereby water and low molecular weight compounds in the solution are caused to pass through the membrane or microporous filter medium of the ultrafiltration equipment and to emerge as ultrafiltrate while the desirable polysaccharide, such as carrageenan or alginate, is retained by the membrane or the like and is recovered in concentrated form.
