Resumen:
|
A rapid throughput method for the quantitation of the oxidation level of intact full bottles of wine based on the 1¯ 33¯1 water suppression pulse sequence is described. The ideal pulse sequence suppresses water in the 1H nuclear magnetic resonance spectrum while uniformly and phase coherently exciting the resonances pertaining to ethyl alcohol at 1.1ppm and oxidation products at 2.1ppm. The anticipated results of the pulse sequence based on simulations are tested in small sample and full bottle standards and an application to the detection of wine spoilage in more than century old wine is provided.
