Changes in the Grape Cane Stilbene Content under Various Conditions of Storage
Original language description
Wine-making produces a variety of biological wastes, such as grape canes, leaves, stems, shoots, etc. These materials constitute attractive sources of biological substances, such as stilbenes (stilbenoids). The grape canes alone possess a considerably greater content of these health-beneficial substances than the berries; of those, trans-resveratrol is among the best known components, in addition to its oligomers, e.g., trans-ϵ-viniferin (dimer) and r2-viniferin (tetramer). This article compares various conditions of storage of grape canes, including exposure of the material to special stress conditions (SSC) such as UV radiation, maceration in water, or application of an elicitor to the grape canes. When grape canes were left dry in a laboratory over the period of several tens of weeks, the content of these substances increased (more than 10 times for trans-resveratrol and by around 50% for trans-ϵ-viniferin and r2-viniferin), while during long-term storage for 1 to 3 years the content of these substances dropped (by up to 30% for trans-resveratrol and trans-ϵ-viniferin). For r2-viniferin, however, it increased by up to 72%. The use of SSC appears to be a special method where the contents of the stilbenes can be changed.
