Photon Counting Study of Reactive Oxygen Scavenging Ability of Foods

Though reactive oxygen promotes aging and is connected with diseases such as cancer, superoxide dismutase (SOD), originally provided to the human body is an enzyme whose function is scavenging reactive oxygen. However, deterioration of the living environment and increasing stress lead to the amount of reactive oxygen being over the processing capacity of SOD; foods are required which work like SOD. In this study, light emission in scavenging reactive oxygen was measured, and reactive oxygen scavenging ability of liquid foods such as coffee, soymilk and so on were examined. A very strong scavenging ability of coffee was recognized.
