PROCESS FOR PRODUCING -g(a)-MONOGLUCOSYLHESPERIDIN-RICH SUBSTANCE

摘要

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 -monoglucosyl 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.
