Title:
PROCESS FOR PRODUCING PURIFIED ANTHOCYANIN AND CRYSTALLINE ANTHOCYANIN
Document Type and Number:
WIPO Patent Application WO/2002/022847
Kind Code:
A1
Abstract:
A process for producing purified anthocyanidin glucoside characterized by comprising cleaving the rhamnose end of anthocyanidin rutinoside with rhamnosidase, converting the anthocyanidin rutinoside component into anthocyanidin glucoside and then purifying and isolating the anthocyanidin glucoside component; or a crystalline anthocyanidin glucoside salt obtained by further crystallizing the purified anthocyanidin glucoside and a process for producing the same. A process for producing anthocyanidin rutinoside characterized by comprising cleaving the glucose end of anthocyanidin glucoside with $g(b)-glucosidase, eliminating via decomposition and then purifying and isolating the anthocyanidin rutinoside component; or a crystalline anthocyanidin rutinoside salt obtained by further crystallizing the purified anthocyanidin rutinoside and a process for producing the same.
