Abstract:

Taking ice grape wine as material,the resveratrol content of ice grape wine was measured and correlation analysis of it and wine color was studied.The experimental results showed that the resveratrol contents in seven ice grape wines were significantly different (P<0.05).The resveratrol content of No.4 ice grape wine was the highest (1.77 mg/L) and its wine color was dark red.The ice grape wine numbered as No.4 possessed that the maximum a^* value (0.59) and the maximal OD₅₀₅ value (6.430).The correlation analysis showed that there were significant negative correlation (r=-0.6717，P<0.05) between the resveratrol content and b^* value (yellow) of ice grape wine and significant positive correlation (r=0.7938，P<0.05) between the resveratrol content and OD₅₀₅ value (red pigment content) of ice grape wine.
