玫瑰花醇提取物对油脂的抗氧化作用

研究了玫瑰花中抗氧化物质提取物对油脂类的抗氧化性。结果表明:玫瑰花中的抗氧化物质对猪油有明显的抗氧化作用,且抗氧化提取物的添加量在试验剂量范围内与其抗氧化性呈正相关;当玫瑰花中提取物添加量为猪油样的0.05%时,其抗氧化效果与0.02%VC相当,且玫瑰花中抗氧化物质与VC、VE、柠檬酸有较好的协同作用,尤其在与VC和VE混合时有最好的协同作用。

Antioxidant effect of flavonoids extracts of rose on lard

The extraction of flavonoids from rose was studied and the antioxidant activity of the extract on lard was evaluated as well.When the concentration of flavonoids in lard was 0.5%,the antioxidative effect was as good as 0.02% ascorbic acid.Meanwhile,when ascorbic acid,citric acid and vitamin E were used together with flavonids,ascorbic acid,citric acid and vitamin E show better synergistic antioxidative activities with flavonids.Especially ascorbic acid and vitamin E have stronger synergistic antioxidative activities when they were put into flavonids.
