This method is used for determination of total phenolic compound concentration in wine using the Astoria Flow systems. The applicable range is 100 to 4000 mg/L gallic acid equivalents (GAE).
Phenolic compounds in wine and juice samples are reduced by Folin-Ciocalteu reagent and the absorbance is measured at 750 nm. The absorbance is proportional to the total phenolic concentration.
Readily oxidized compounds (i.e. ascorbic acid, sulfur dioxide) could interfere.
