An intervention of these cations in the oxidative processes was found, since the evolution of the parameters sensitive to oxidation depends on the concentration of these cations in wine. Manganese and iron play an important role in chemical processes with acetaldehyde: manganese favors their formation, and iron catalyzes acetaldehyde combination with phenolic compounds.}, issn = {0002-9254}, URL = {https://www.ajevonline.org/content/46/3/380}, eprint = {https://www.ajevonline.org/content/46/3/380.full.pdf}, journal = {American Journal of Enology and Viticulture} }
