螯合剂对桔皮中提取物抗氧化作用的影响

EFFECT OF CHELATOR ON ANTIOXIDATION OF MATTER EXTRACTED FROM ORANGE PEEL

将桔皮中提取到的抗氧化物质 ,分别添加到植物油和猪油中 ,研究磷酸、酒石酸、柠檬酸和 EDTA这 4种螯合剂对抗氧化物性能的影响。结果表明 ,当抗氧化物在猪油中的添加浓度为 0 .5 %时 ,4种螯合剂对抗氧化物都有很强的增效作用。当在植物油中抗氧化物的添加量为 0 .2 %和 0 .6 %时 。

Putting antioxidation mattes extracted from orange peel into the vegetable oil and lard respectively,the effect of chelators (phosphate,tartaric acid,citric acid,EDTA)on the property of antioxidation was studied. The test results showed that four chelators have very strong synergy action when antioxidation matter concentration in the lard accounts for 0.5%. Tartaric acid and citric acid have a little synergy action when antioxidation matter concentration in the vegetable oil account for 0.2%and 0.6%.
