Abstract
The 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.
