Latest Patents

Hyang-Ja You holds a patent for the "Separation and purification of low molecular weight chitosan using a multi-step membrane separation process." This patent describes a method whereby the natural polymer α-chitosan, extracted from the shells of crustaceans, can be effectively separated and purified into low molecular weight chitosan or oligosaccharide chitosan with high yield. The process involves reacting a chitosan mixture of various molecular weights with an acid in the presence of an enzyme while applying ultrasonic treatment. The resulting mixture is then combined with pure water to create an aqueous solution with a chitosan concentration ranging from 1% to 50%. This solution undergoes continuous membrane filtration under pressure, followed by a second fractionation and separation technique using a suitable membrane based on the desired molecular weight cut-off.
