DETERMINATION OF TANNINS IN ALCOHOL-CONTAINING LIQUIDS

DETERMINATION OF TANNINS IN ALCOHOL-CONTAINING LIQUIDS

The paper presents experimental findings on the influence of caramel color on the UV absorption spectra of tannin-containing liquids. The presence of caramel color in alcohol-containing brandy-type liquids is demonstrated to affect optical density at 280 nm, and therefore the results of spectrophoto...
