요약 | Red wine quality is known to improve with oxidation, typically as a result of exposure to oxygen. These benefits are based on the reaction of acetaldehyde with flavonoids in red wine. Acetaldehyde forms ethylidene bridges between flavonoids resu |
요약 | As a replacement for oxygenation techniques, I investigated the use of exogenous acetaldehyde additions to improve the color stability and mouthfeel of red wine. I first determined the viability of exogenous acetaldehyde treatment of a red wine |
요약 | In order to understand the role of wine components in the reaction of acetaldehyde with wine flavonoids, I assessed the effect of pH, dissolved oxygen, and sulfur dioxide (SO2) in model wine solutions. The rate of reaction of acetaldehyde with c |
요약 | Based on the efficacy of acetaldehyde in a system with an equimolar concentration of bisulfite in the previous study, I then explored the reactivity of aldehydes from bisulfite adducts. I synthesized alpha-hydroxyalkylsulfonates from bisulfite a |
요약 | In order to confirm the application of exogenous acetaldehyde in red wine production, I investigated the treatment of red wine with exogenous acetaldehyde, the acetaldehyde-bisulfite adduct, and oxygenation after alcoholic fermentation. A reason |
요약 | Overall, I demonstrated that exogenous acetaldehyde treatment is a viable alternative to oxygenation for improving the color stability of red wines. At low concentrations (22 mg/L), winemakers could use acetaldehyde to significantly improve colo |
