| 摘 要： | 目的研究苹果酒对自由基的抑制作用。方法采用分光光度法测定苹果酒对DPPH自由基、超氧阴离子自由基和羟基自由基的抑制作用,还原力的测定采用Fe3 还原法。结果苹果酒中的酚酸含量与抗氧化能力呈正相关(除羟基自由基外),其中酚酸含量较高的雪儿苹果干酒、雪儿苹果果酒和英国B lACKTHORN抗氧化能力较强。结论苹果酒均有一定的抗氧化性,具有良好的保健功能。

| Abstract: | Aim To study the inhibition of free radicals by six kinds of apple ciders.Methods Antioxidant activity of apple ciders was assayed through some methods such as DPPH radicals,super-oxide anion radicals,hydrogen radicals,reducing power.Results A positive correlation between total phenolic content and antioxidant activity,except for hydrogen peroxide.These data indicated that Snowy dry cider,Snowy sweet cider and BLACK-THORN were better antioxidant capacities than other three apple ciders.Conclusion These apple ciders had significant antioxidant activity.This study will supply the theory for healthy function of apple ciders. |
