This paper discusses phenolic oxidation in the context of wine and its multiple components. We have compiled available information on wine oxidation, proposed hypotheses on some unresolved matters, suggested areas for further research, and discussed practical enological implications.
24 lip 2020 · Wine oxidation and ageing involve many complex chemical pathways and reaction mechanisms. The purpose of this study is to set up new and reproducible accelerated red wine ageing tests and identify chemical oxidation or ageing molecular markers.
17 cze 2016 · Oxidation is generally the limiting factor in the preservation of wine. Several important historical wine authors have reflected on the significance of oxidation. In principle, redox potential measurements could be useful for evaluating whether wine is excessively reduced or oxidized.
3 gru 2021 · In order to obtain information on the oxidative behavior of red wines, oxygen consumption rates and electrochemical changes (cyclic voltammetry) were measured for nine red wines subject to three different accelerated ageing tests: chemical (with hydrogen peroxide), enzymatic (with laccase from Trametes versicolor), and temperature (at 60 °C).
6 sie 2019 · The sporadic oxidation of white wines remains an open question, making wine shelf life a subjective debate. Through a multidisciplinary synoptic approach performed as a remarkable case study...
24 lip 2020 · Three accelerated and reproducible ageing tests were developed: a heat test (60 °C); an enzymatic test (laccase test; a chemical test (hydrogen peroxide test). Depending on the test, oxygen consumption was significantly different.
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).
