Abstract:The change of flavonoids in brier grape wine during the storage under different conditions were studied and the results showed that main flavonoids in brier grape wine decreased with the storage time prolonged. Proper free sulfer dioxide, lower temperature, and full tank storage could prevent the decreasing of free anthocyanin, procyanidine, and total flavonoids. Under the conditions of 40 mg/L free sulfer dioxide and full tank storaged at 16 ℃ for twelve months, the preserving rates of free anthocyanin, procyanidine, and total flavonoids were 99 31%, 76 50%, and 92 12%, respectively.
