摘  要:
采用硫氰酸铁(FTC)法测定了萝卜红色素对亚油酸过氧化反应(40℃)的抑制作用;采用气相色谱法测定了其对芥菜籽油过氧化反应中(93℃)氧的吸收的抑制作用。天然萝卜红色素的抗氧化能力与同浓度的BHT相近,0.01%的添加量即可达到93%以上的抑制率。萝卜红色素是一种应用前景广阔的具有抗氧化功能的天然食用色素。

摘  要:
FTC method was used to determine inhibition effect of red radish pigment to peroxidation of linoleic acid(40℃)Gas chromatography was adopted to measure inhibition action of red radish pigment in the oxygen absorption during the peroxidation of canola oil(93℃).Natural red radish pigment had almost the same antioxidative activity as BHT at the same concentration.The inhibition ratio,coold be achiewed more than 93%by the 0.01%pigment addition.Red radish pigment was a natural,edible and strong antioxidative pigment with broad application prospects.
