• Resumen

  • 2,5-Dimethyl-4-hydroxy-3(2H)-furanone (furaneol) was reported to be responsible for the strawberry-like aroma in some Vitis labrusca and hybrid (V. labrusca × V. vinifera) winegrapes. This study identified furaneol glucopyranoside in the juice of a Japanese hybrid grape, Muscat Bailey A [V. labrusca (Bailey) × V. vinifera (Muscat Hamburg)], using high-performance liquid chromatography�tandem mass spectrometry. The concentrations of furaneol glucopyranoside and furaneol in the juices of Concord (V. labrusca) and Muscat Bailey A were much higher than those in the juices of other V. vinifera varieties. It was also demonstrated that furaneol and its glucopyranoside were accumulated mainly in Muscat Bailey A berry flesh. These findings are expected to contribute to the elucidation of the mechanism of formation in grapes and to the understanding of the characteristic strawberry-like aroma of Muscat Bailey A wines.
