ABSTRACT:
Provided are a process for producing purified anthocyanidin glucoside in which a rhamnose end of anthocyanidin rutinoside is cleaved using rhamnosidase to convert the anthocyanidin rutinoside component into anthocyanidin glucoside, the anthocyanidin glucoside component being then purified and isolated; or a crystalline anthocyanidin glucoside salt obtained by further crystallizing the purified anthocyanidin glucoside and a process for producing the same.Also provided are a process for producing purified anthocyanidin rutinoside in which a glucose end of anthocyanidin glucoside is cleaved using β-glucosidase to degrade and remove the end, the anthocyanidin rutinoside component being then purified and isolated; or a crystalline anthocyanidin rutinoside salt obtained by further crystallizing the purified anthocyanidin rutinoside and a process for producing the same.
