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

(VIII) Color Development of Sake Caused by Exposure to Sunlight without the Participation of Deferri-ferrichrysin

Abstract

In the course of studies on color development of sake caused by exposure to sunlight with the participation of deferri-ferrichrysin (reaction I), other color development reactions in which deferriferrichrysin did not participate were anticipated.
Sake fraction which was adsorbed on Amberlite IR-120 and eluted by N·NaOH was colored by: exposure to sunlight. From studies on this fraction, the scheme of the reaction was presumed as follows and this was named reaction II.
