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...

Antioxidant activity of fresh water kefir drink and its extract with (0.125–5 mg/ml) was evaluated using 2,2,-diphenyl-1-pricrylhydrozyl (DPPH) scavenging method, and inhibition of ascorbate autoxidation and the reducing power of water kefir were determined, Butylated hydroxyanisole (BHA) and ascorbic acid were used for comparison.
