In order to research in the change of physical properties in the period of wine aging,1H nuclear magnetic resonance spectroscopy ('H NMR) was applied to study the hydrogen bonding structures of ethanol-water system in different conditions; In addition, a multi-parameter analyzer was used to explore the change mechanism of some basic electrochemistry parameters of different dry red wines and dry white wines such as pH、oxidation reduction potential value (ORP)、conductivity.
The interaction between hydroge...
