Patent ID: 7217817

Claim:
A method for producing a non-gelable agarobiose-containing composition which contains 5 to 60% (w/w) of agarobiose and 40 to 95% (w/w) of at least one agarooligosaccharide other than agarobiose, the method comprising: a. preparing a mixture containing an agarobiose-containing material of agar or purified agarose and 0.1 to 50% (w/w) of a solid acid; b. decomposing the agarobiose-containing material by incubating the mixture at 50–100° C. for 30 minutes to 12 hours; and c. recovering an agarobiose-containing composition from the decomposition product; said method being further characterized in that said agaroboise containing composition, when solubilized in water to provide a solution, will not gelate even if the solution is cooled to its solidifying point.
