| Research Abstract |
Applications of metabolomics techniques along with chemometrics provide an understanding in the relationship between metabolome of red wine and its quality. Ultra-performance liquid chromatography coupled with time-of-flight mass spectrometry (UPLC-TOFMS) allowed a high-throughput analysis. Using this technique, a wide range of metabolites were investigated. A set of red wines during bottle storage was analyzed. Red wines with different storage time were discriminated through orthogonal partial least squares discriminate analysis (OPLS-DA). Furthermore, grape anthocyanins and pyranoanthocyanins detected in red wine were found to be significant markers to bottle aging.
