Copigmentation potential of overripe seeds from sun‐dried white grapes on anthocyanins colour and stability by differential colorimetry

Summary Overripe seeds are wine by‐products from grapes submitted to postharvest sun drying, which induce phenolic biosynthesis and polymerisation. Overripe seeds from Pedro Ximénez (PX) and Moscatel (MO) sun‐dried grapes were compared as copigments sources to modulate grape anthocyanin (GA) colour and stability in simulated wine conditions. RRLC/MS analysis proved that overripe seeds contain specific phenolic mixtures capable of inducing...
