Photodegradation of Riboflavin in Milks Exposed to Fluorescent Light

Photodegradation of Riboflavin in Milks Exposed to Fluorescent Light

Photodegradation of riboflavin in 50-ml samples of fluid milks exposed to fluorescent light (2690 lux) followed first-order reaction kinetics, and the reaction rate (s−1) averaged 1.86×10−5 in skim milk and 1.47×10−5 in whole milk. Additional evidence led us to conclude that photodegradation of ribo...

Zusammenfassung:Photodegradation of riboflavin in 50-ml samples of fluid milks exposed to fluorescent light (2690 lux) followed first-order reaction kinetics, and the reaction rate (s−1) averaged 1.86×10−5 in skim milk and 1.47×10−5 in whole milk. Additional evidence led us to conclude that photodegradation of riboflavin proceeds prior to the appearance of a light-induced off-flavor.
