Abstract
After the evidence in hop of the cysteinylated precursors of 3-sulfanyl-4-methylpentan-1-ol (3S4MPol) and 3-sulfanylhexan-1-ol (3SHol), S-glutathione precursors were recently investigated in Amarillo, Hallertau Blanc and Mosaic. The aim of the present work was to assess the linked-potential in two other dual-purpose hop cultivars, namely Citra and Sorachi Ace. The occurrence of S-3-(1-hydroxyhexyl)glutathione (G-3SHol) was confirmed in all cultivars, at levels well above those reported for the cysteinylated counterpart, while S-3-(4-methyl-1-hydroxypentyl)glutathione (G 3S4MPol) revealed more specific of the Hallertau Blanc variety.
