Methodological issues of grape and wine water evaluation by quantitative nuclear magnetic resonance deuterium spectroscopy (2H(D)-qNMR)
Journal: BIO Web of Conferences
Year: 2023

The new methodological approach of rapid evaluation of intracellular grape and wine water without sample preparation, based on the quantitative nuclear magnetic deuterium spectroscopy ( 2 H(D)-qNMR) is suggested and developed under the research program carried out under the scientific grant of the International Organization of Vine and Wine (O.I.V.). The approach provides a quantitative high precision measurement of the deuterium content in water based on the direct dependence of the areas of NM
