Studies on the Sunlight Flavor of Beer

Part VII. Correlation of the Occurrence of the Sunlight Flavor of Beer to Humulone, Lupulone and Related Compounds (2)

Abstract

The sunlight flavor occurred when humulone or lupulone was added to beer after main fermentation was completed, and among the other phenols used, only acetolupuphenone [1-acetyl-3, 3, 5-(γ, γ-dimethylallyl)-cyclohexadiene-(1, 5)-diol-(2, 6)-on(4)] was found to cause the sunlight flavor.
