Question & Answer
Choose the Best Answer
By measuring the absorbance at 280 nm
By comparing the color intensity after reaction with the reagent
By using UV light to detect volatile compounds
By assessing the pH of the wine sample
Understanding the Answer
Let's break down why this is correct
The reagent reacts with phenolic molecules and turns blue. Other options are incorrect because 280 nm is a wavelength used for proteins, not for the blue color made by the reagent; UV light can detect volatile compounds, but the Folin reagent is not a volatile detector.
