5 maj 2023 · Oxidation happens when a wine’s exposure to air triggers a series of chemical reactions that convert ethanol (what we commonly refer to as alcohol) into acetaldehyde. This concentrates color and creates aromas and flavors generally considered to be grassy, nutty or apple-y.
15 sty 2021 · Oxidation, in wine terms, refers to a group of chemical reactions that occur when wine comes into contact with air. It can result in a wine losing its primary fruit characters and developing a brown hue.
23 paź 2016 · Basically, all oxygen needs is a simple catalyst for the reaction to occur. Anthocyanins and phenols, two components of wine, are very susceptible to oxidation. When oxidation takes place, the...
30 paź 2024 · Simultaneously, the recent advancements in understanding the molecular pathways involved in wine oxidation are also discussed. The paper first explores the process of oxygen dissolution and the complex transformations that occur in polyphenols during oxidation. It then reviews the current methods of micro-oxidation (MOX) and over-oxidation (OOX).
2 kwi 2024 · The crucial importance of producing wines that are free of deficiencies and have sensory characteristics that appeal to consumers is largely related to wine oxidation. More and more research is focusing on understanding and applying wine oxidation to produce consumer-appealing wine products.
1 cze 2011 · The present review aims to show the state of the art on the oxidation mechanisms occurring in wines, as well as the methods to monitor, classify and diagnose wine oxidation. Wine oxidation can be divided in enzymatic oxidation and non-enzymatic oxidation.
30 paź 2024 · In this comprehensive review, the initial stages of non‐enzymatic wine oxidation are examined. The pivotal roles played by polyphenols, oxygen, iron, copper, and SO2 in this complex oxidative ...
