[Determination of polyphenolic complex in wines by electrochemical methods and using the enzymes tyrosinase and laccase].
Prikl Biokhim Mikrobiol. 2004 May-Jun; 40(3):359-65.PB

Abstract

Several red wines were studied to find a correlation between physicochemical parameters characterizing the antioxidant status of wine and total content of phenols in samples. The content of dissolved oxygen (its value varied from 0.75 to 3.28 mg/ml), pH (3.10-3.63), redox potential (-186 to -106 mV), mass concentration of free and total sulfur dioxide (10-30 and 36-200 mg/dm3, respectively), absorption spectra, and total phenol content were determined. The wines fell into two main groups-with a relatively low (1850-2050 mg/dm3) and high (2300-2900 mg/dm3) contents of polyphenols. It was demonstrated that physicochemical parameters (except for the content of sulfur dioxide) correlate with the total phenol content in the wines studied.
