Vegetables are rich source of antioxidative components such as ascorbic acid and polyphenols, which scavenge free radicals and reactive oxygen species and prevent life-style related diseases. In this work, the changes of radical-scavenging activity in shredded red and green cabbage leaves during storage were determined as well as ascorbic acid and polyphenol contents.
Shredded cabbage leaves were stored at 10degreesC for 7 days in the presence or absence of oxygen. Radical-scavenging activity, ascorbic acid content, and polyphenol content of shredded cabbage leaves remained for 7 days in the presence and absence of oxygen. These results demonstrate that the radical-scavenging activity, ascorbic acid, and polyphenols are stable in shredded cabbage leaves and that oxygen does not affect the activity and active components.
