Patent ID: 10774351

Abstract:
The present invention relates to a method of preparing an anthocyanin oligomer using a coenzyme derived from an Aspergillus sp. strain, and more particularly to a method of preparing an anthocyanin oligomer by fermenting an anthocyanin monomer with a coenzyme of Aspergillus niger, which is a kind of Aspergillus sp. strain. According to the present invention, in order to overcome contamination problems during the culturing process using Aspergillus niger, a coenzyme of Aspergillus niger is extracted and the fermentation process is performed using the same, whereby an anthocyanin oligomer characterized by reduced concern of contamination and superior radical-scavenging effects, compared to existing anthocyanin monomers, can be produced. Also, an anthocyanin oligomer, obtained through fermentation using glucosidase as an enzyme contained in the coenzyme, can exhibit excellent fermentation efficiency and radical-scavenging ability, and polymerization of the anthocyanin oligomer can be confirmed even upon the fermentation of the enzyme including glucosidase.
