PCT No. PCT/JP98/00977 Sec. 371 Date Nov. 23, 1998 Sec. 102(e) Date Nov. 23, 1998 PCT Filed Mar. 10, 1998 PCT Pub. No. WO98/42859 PCT Pub. Date Oct. 1, 1998The present process for producing a high alpha -monoglucosyl hesperidin content product is characterized in that it comprises the steps of contacting glucoamylase and alpha -L-rhamnosidase simultaneously or randomly with a solution containing alpha -glucosyl hesperidin and hesperidin to obtain a mixture; crystallizing and separating alpha -monoglucosyl hesperidin in and from the mixture; and collecting the resulting alpha -monoglucsyl hesperidin. From solutions containing alpha -glucosyl hesperidin and hesperidin, the present invention facilitates the production of a high alpha -monoglucosyl hesperidin content product which does not substantially contain hesperidin, beta -monoglucosyl hesperetin, and hesperetin, and has an extremely-superior water-solubility.
