Phenolic terpenes
WebJan 1, 2024 · The phenolic compounds are a vast class of secondary metabolites performing several roles for the defense and survival of plants. Their structure varies extensively, and thus they have been classified into groups according to the pattern of their basic skeletons. WebMar 30, 2024 · Most terpenes in wine are generated via the hydrolysis of terpene glycosides (TGs) in grape berries during fermentation. Hence, the role of the phenolic matrix effect in terpene formation should be investigated in detail with the aim of improving the quality of fruity and floral aromas of wine.
