Oxidative Stability

In order to maintain oxidative stability of whites during aging is a real challenge.  This particular study evaluated the antioxidant activities of soluble extracts of a number of oenological yeast derivatives with increased glutathione (GSH) enrichment.  The specific GSH enriched derivatives showed to be on average 3,3 times more efficient in “scavenging” radical species in comparison to the non-enriched derivatives.  This research opened up new insights into the analysis and development of yeast preparations dedicated to improve oxidative stability of wines.
