The role of UV-visible spectroscopy for phenolic compounds quantification in winemaking

UV-Visible spectroscopy, a pivotal tool in winemaking, facilitates the quantification of phenolic compounds. This technique, relying on the characteristic absorption peaks of phenolics, enables the determination of Total Phenolic Content (TPC) and specific compounds. Essential for quality control, UV-Vis spectroscopy monitors fermentation, maturation, and influences from grape variety, ensuring product consistency. Challenges include potential interferences, emphasizing the importance of precise sample preparation. In summary, UV-Visible spectroscopy emerges as a rapid, reliable method for assessing and optimizing the phenolic composition of wines. The abstract emphasizes the pivotal role of UV-Visible spectroscopy in winemaking, providing a reliable and cost-efficient means for the accurate quantification of phenolic compounds. Leveraging the unique spectral fingerprints of phenolics, this technique enables the determination of Total Phenolic Content (TPC) and specific compounds, facilitating dynamic monitoring throughout fermentation and maturation. Beyond its efficiency, UV-Vis spectroscopy establishes correlations between analytical data and sensory attributes, offering insights into the intricate relationship between phenolic composition and wine characteristics. Challenges, such as potential interferences, underscore the importance of meticulous sample preparation. In summary, UV-Visible spectroscopy emerges as a valuable tool for both routine analysis and in-depth exploration of the phenolic landscape, contributing to the optimization of winemaking processes and the assurance of product quality.
