Abstract: The anti－oxidative properties of malted milk drink,ovaltine,emiched bythe extract of bamboo leaf(Ebl),were investigated here.Sensory evaluation teat figured out that the optimum additive rate of Ebl972 was 1％. At this ratio,the anti－free radical and antioil oxidation capabilities of the enriched ovaltine were remarkably improved,measured by chemiluminescence and thiobarituic acid (TBA) methods respectively;and 1％Ebl972 still protected effectively VA and VE in ovaltine from oxidation loss.Results showed that enriching Ebl into ovaltine improved its commodity property significantly besides the endowment of specific functionality.So it could be concluded that Ebl was not only a kind of excellent bio－flavonoid healthy factor,but also a potent food antioxidant.
