Title:
METHOD OF FORMING AGGLOMERATES OF POLYSACCHARIDE WITH HYDROPHOBIC GROUPS
Document Type and Number:
WIPO Patent Application WO/2000/059948
Kind Code:
A1
Abstract:
A method of forming agglomerates of a polysaccharide containing hydrophobic groups in water which comprises adding the polysaccharide to water to swell it and treating the mixture with a homogenizer at a pressure of 9.8 to 490 MPa (100 to 5,000 kgf/cm?2¿) to disperse the swollen polysaccharide. Thus, homogeneous agglomerates of a polysaccharide containing hydrophobic groups are stably and easily formed in a large quantity in a short time period.
