Quantification of total polyphenol content in wine lees by conventional optical and photoacoustic spectroscopy
The He-Ne laser (632.8 nm) and photoacoustic spectroscopy (PAS), a variant of the photothermal methods, were combined with the Folin-Ciocalteu colorimetry method to determine total phenolics in wine lees.
