ABSTRACT:
The invention provides a process for preparing L-rhamnose by hydrolyzing a rhamnosidic bond of a glycoside having rhamnose in a terminal position, by enzymatically hydrolyzing the glucoside with an enzyme combination comprising biological structural material degrading enzyme and a naringinase preparation which has a higher rhamnosidase activity than beta-glucosidase activity. Preferably the enzyme combination having rhamnosidase activity together with additional enzyme activity is a selected partially purified enzyme preparation having high rhamnosidase activity and low glucosidase activity together with biological structural material degrading activity. More preferably the additional enzyme activity is derived from an enzyme of the group consisting of protease, lipase, pectinase, cellulase and hemicellulase.
