Document Type and Number:
WIPO Patent Application WO/2013/051146
Kind Code:
A1
Abstract:
A method for producing a depolymerized konjak glucomannan, said method being characterized by comprising adding to a konjak powder containing glucomannan a mixed aqueous solution of an inorganic acid with an alcohol in such an amount as to give a bath ratio of 1-5 to thereby adjust the pH value of the reaction system to 2 or lower, and then heating the resultant mixture at 70-130oC; and a depolymerized konjak glucomannan which has a weight-average molecular weight (Mw) of 3,000-100,000 and a polydispersity (Mw/Mn) of 1-2.
