PROBLEM TO BE SOLVED: To obtain the subject partial hydrolyzate that has high improvement effect of bowel movement and can be drunk as a liquid beverage, as it shows a low viscosity, when it is dissolved in water, by allowing a specific enzyme to act on psyllium as a dietary fiber. SOLUTION: This partial hydrolyzate is prepared by allowing (A) an enzyme that can hydrolyze psyllium as pectinase, hemicellulase, and their combination, preferably pectinase to act on (B) psyllium. The partial hydrolyzate of psyllium is prepared by adding the component B to water, and the component A is allowed to act on the component B and the amount of the component B is preferably <=10 wt.% based on the water. The amount of the enzyme (the component A) is 0.5-6 U in the total of the enzymatic potency to the psyllium per 1 g of the component B. In a preferred embodiment, the viscosity of 4 wt.% aqueous solution of the psyllium partial hydrolyzate is 30-200 cP with the type B viscometer at 4 deg.C, 60 rpm and a pH of about 4. |
