Scavengingcapabilityfor free radicals of fruit and vegetable juice

This study designed two different reaction systems:superoxide anion,hydroxyl radical to research on free radical scavenging effect of fruit and vegetable juice with three kinds of treatment: peeled fresh juice,peeled boiling juice and fresh juice.The results showed that several fruit and vegetable juice had some scavenging capability for free radicals.In the superoxide anion system,the average scavenging rate of star fruit was greater than pear;soybean sprouts was greater than mungbean sprouts.In the hydroxyl radical system,the average scavenging rate of pear was greater than star fruit;mungbean sprouts was greater than soybean sprouts.
