摘要
以猪油、芝麻油为底物,采用碘量法研究了苹果多酚的抗氧化性能及与螯合剂柠檬酸的协同增效作用.结果表明,苹果多酚对油脂的脂质过氧化有良好的阻断作用,且抗氧化效果随其用量的增加而加强;柠檬酸对苹果多酚具有明显的协同效应.
The antioxidative effects of the extracts from apples were measured by the Na_2S_2O_3-I_2 titrimetric method using lard and sesame oil as substrates.The results show that the apple polyphenols have significant resistance to the lipid peroxidation of oil,and citric acid has synergistic effects to the antioxidation of the extracts.
