摘要: 以浸泡型杨梅酒为模型,通过测定不同贮藏时期酒中黄酮含量、花色苷含量、最大吸收波长以及色度的变化,研究黄酮对杨梅花色苷的辅色作用。结果表明:浸泡型杨梅酒在不同贮藏时期,黄酮含量呈先上升后下降的趋势,在第91天达到最高值0.028mg/mL;花色苷含量呈先上升后下降的趋势,在第63天达到最高值22.38mg/L;酒中杨梅花色苷最大吸收波长发生蓝移,呈逐渐降低的趋势;黄酮含量与色调角、最大吸收波长和花色苷含量成极显著正相关。

Abstract: The co-pigmentation effect of flavonoids on red bayberry anthocyanins was investigated by determining changes in flavonoid content and anthocyanin content, maximum absorption wavelength and color of red bayberry wine during different storage periods. Results showed that flavonoid content exhibited a trend to first crease and then decrease and reached the maximum level of 0.028 mg/mL after 91 days of storage. The change of anthocyanin content was similar with flavonoids and reached the highest level of 22.38 mg/L after 63-days storage. The maximum absorption wavelength of red bayberry anthocyanins exhibited a blue shift and a gradual decrease. The content of flavonoids revealed a positive correlation with the color parameter h, maximum absorption wavelength or anthocyanin content.

Key words: immersed red bayberry wine, flavonoids, anthocyanins, co-pigmentation
