ANTIOXIDANT POTENCY OF WATER KEFIR
Reactive oxygen species (ROS) have strong relationship with several diseases. Many fermented foods were reported to be important sources for antioxidant compounds. Antioxidant activity of water kefir never reported in the scientific literature. The objective of this study was to detect and investiga...
