The effect of exposure to fluorescent light on sparkling wine and the still wine from which it
was made was studied in green and flint (clear) bottles. Although the green glass afforded …

… broad wavelength fluorescent lighting (Dozon & Noble, 1989). … 450 nm and an increase in
absorbance around 520 nm after … nm (no riboflavin added) to 520 nm with added riboflavin. …

… Catechin tannins (condensed tannins) Due to their high absorption capacity of UV light,
especially that absorbed by riboflavin at 370 nm, which prevents it from reacting with methionine. …

… In the experimental conditions adopted (Met 75 mg/L, RF 1.7 mg/L pH 8.0, light exposure at
wavelengths 405–640 nm with maximum at 430, 550 and 640 nm for 6 h), MeSH was the first …

… here at 440 nm, other important wavelengths are 280 nm (… at 280 and 440 nm as well as
shoulder at 310 nm. Further, its … at 280 and 460 nm as well as shoulder at 310 nm, and its …

… The absorbance measurements were recorded at 440 nm and spectra were recorded from
200 to 600 nm using a Cary Bio50 UV/Vis spectrophotometer. CIELab measurements were …

… riboflavin was found to be 0.26 (435 nm irradiation). No dependence of the quantum yield
or product distribution on the irradiation wavelength was found over the range 365–90 nm. …
