A liquid material including a polysaccharide is manufactured by creating a mixture of polysaccharides and an aqueous solvent or an aqueous cosolvent with organic solvents at a temperature at which gelation does not occur. The mixture is also irradiated at this lower temperature, such as with ultrasound waves in combination with stirring and/or bubbling of inert gases. to apply ultrasound to a mixture of. Compared with conventional reactions with low concentration solutions, the product yield and advantageous mechanical properties are significantly increased. Depolymerization (decomposition, disassembly) of polysaccharide in the liquid material does not occur to any substantial degree, and the molecular structure of the polysaccharide is maintained. Further, the liquid material does not gel even when the temperature is raised, and thus, its fluidity is maintained, despite polysaccharides being maintained at a high concentration. The liquid material is applicable to myriad industries, including pharmaceuticals and health foods.
A method for producing a polysaccharide-including liquid material, comprising:
The method according to claim 1, wherein the mixture is irradiated with ultrasonic waves. The method according to claim 4, wherein the temperature at which the ultrasonic waves are applied is between about 1° C. and about 25° C. below a gelation temperature of the mixture.
The method according to claim 10, wherein stirring the mixture further comprises bubbling of an inert gas through the mixture.
