Abstract
The samples of the newly-produced uncatalyzed aged wine,naturally-aged wine and electro-catalyzed wine are analyzed by nuclear magnetic resonance. The result shows theΔδof the naturally-aged wine is bigger than the newly-produced uncatalyzed aged wine and theΔδof the electro-catalyzed wine is bigger than the newly-produced uncatalyzed aged wine,which results from the association of hydrogen bond and the chemical shift of the water in naturally-aged wine and electro-catalyzed wine towards low field.
