Studies on Changes in Color and Flavor of Sake caused by Exposure to Light and Storage

(VI) Color Development of Sake caused by Exposure to Sunlight with the Participation of Deferri-ferrichrysin

Abstract

Deferri-ferrichrysin (DFCY) participates in color development of sake caused by exposure to sunlight. This reaction was named deferri-ferrichrome reaction (Reaction I).Since DFCY alone did not cause color development, other components which participated in the Reaction I were studied.From the results of fractionation of sake with ion-exchange resins, the scheme of the Reaction I was presumed as follows
