ABSTRACT:
A process for the production of a hopped malt beer wherein a processing liquid containing riboflavin is hopped to form the desired beverage. The improvement comprises subjecting that processing liquid to an effective amount of actinic radiation of a wavelength adopted to decompose the riboflavin and thereby reduce the amount thereof, whereby a beer having enhanced light stability is obtained.
