Many winemaking practices have changed in consequence, as well as the additives used, especially in terms of the health aspects of the substances used and their concentration in the final product.
This study presents a rapid method to monitor the oxidative state of model solutions containing catechins, with three technological additives added: ascorbic acid, potassium metabisulfite and gall tannins and stored for 15 days at 40 and 50 °C.
This study is a starting point for the development of fast analytical methods that are easy and affordable to use and that could offer potential advantages to wine estates.
